Denna studie undersöker möjligheten att ta fram en mer hållbar och cirkulär armatur i ett samarbete med ateljé Lyktan i Åhus, där utgångspunkten är deras armatur RIFF pendel. Studien utgår huvudsakligen utifrån ett materialperspektiv där en översyn av delar inom armaturen ses över för att skapa en cirkularitet kring produkten. Teorin har sin utgångspunkt inom design för hållbar utveckling där förhållandet till cirkulär ekonomi ligger i fokus, detta för att utforska med ett materialdrivet designperspektiv utgå från själva materialet med krav som en huvudkaraktär i utformandet. För att uppnå ett resultat och slutsats utförs en förstudie som research metod och en designspecifikation skapas för att sammanställa allt som armaturen ska klara av att lösa och bidra med. Researchen följs upp av en designprocess för att undersöka och konkretisera de designmål och kriterier som produkten behöver uppnå. Studien ger förslag till ateljé Lyktan i form av en skärm och och uppgradering av befintliga ljusmotorn för RIFF armatur med ett cirkulärt material från en förnybar resurs., This study examines the possibility of developing a more sustainable and circular luminaire in collaboration with ateljé Lyktan in Åhus, based on their RIFF pendant luminaire. The study primarily focuses on a material perspective, reviewing parts within the luminaire to create circularity around the product. The theory is based on design for sustainable development where the relationship to the circular economy is in focus, this to explore with a material driven design perspective starting from the material itself with requirements as a main character in the design. To achieve a result and conclusion, a preliminary study is conducted as a research method, and a design specification is created to compile all the aspects that the luminaire needs to solve and contribute to. The research is followed by a design process to investigate and concretize the design goals and criteria that the product needs to achieve. The result of this study provides suggestions to ateljé Lyktan in the form of a shade and an upgrade of the existing light engine for the RIFF luminaire with a circular material from a renewable resource.

Denna studie tar ståndpunkt inom forskning genom design för att utforska fenomenet springback inom trädetaljer. Inom bakgrund utforskas möbelsnickarstudier och grundläggande fysik med inblick inom hållfasthetslära. Detta för att förstå problemområdet i kontext av näringsverksamhet och bearbetningsmetoder, för en fördjupning av grundkunskap vad som sker inom ett material när knäckning vid böjning uppstår. Studien tar även del av formstabilitetsstudier för att identifiera primära faktorer som skapar springback. Inom teorin utforskas cirkulär ekonomi, Design for Sustainability och Material Driven Design för förståelse av materialkretslopp och materialets vikt vid formgivningen. I metoddelen utforskas och utformas ett förfaringssätt baserat på en metodik inom Material Driven Design med fyra steg utformad av Karana, dessa fyra steg utgår från tre givna scenarion varav studien använde det scenario baserat på användning av redan kända material (ask, hudlim och lintyg). Inom metod utforskas hur man kan böja material med moderna metoder som laserskärare. Detta leder vidare till att det skapas ett nytt perspektiv och en grafisk layout för att hålla material platta där vrid inte önskas. En produkt ritad av studenten tidigare presenteras i slutet av studien med syfte att skapa kontext men primärt visa inom vilka områden det skapade kunskapsbidraget verkar för att skapa formstabilitet., This study takes a stand in research through design to explore the phenomenon of springback in wooden details. Within the background, furniture carpentry studies and basic physics are explored with insight into solid mechanics. This to understand the problem area, context of business activities and processing methods, to get a deepening basic knowledge of what happens within a material when buckling during bending occurs. The study also takes part of shape stability studies to identify primary factors that create springback. Within the theory circular economy, Design for Sustainability and Material Driven Design are explored to understand material cycles and the importance of materials in design. In the method chapter, an approach based on a methodology in Material Driven Design is explored and designed with four steps designed by Karana, these four steps are based on three given scenarios, of which the study used the scenario based on the use of already known materials (ash, hide glue and linen fabric). The methods explore how to bend materials with modern manufacturing with laser cutting. This leads to a new perspective and a graphical layout is created to keep materials flat where warping is not desired. A product designed by the student earlier is presented at the end of the study with the aim of creating context but primarily showing in which areas the created knowledge contribution works to create shape stability.

Product development can be taxing for the environment. When it comes to hardware products then a lot ofthe materials generally involved are based on finite resources such as fossil fuels. As the most commonlyused materials are rarely biodegradable, they often end up in landfills where they end up being harmfulboth to the environment and its inhabitants for a very long time. During recent years some companieshave started combating this through getting involved in the development and implementation of moresustainable alternatives. One of these companies trying to implement more sustainable materials isInteresting Times Gang, who now also wishes to develop new products by using mycelium - theunderground network of threads produced by fungi. This as mycelium poses a lot of sustainable propertiessuch as biodegradability, a high degree of moldability as well as being a cultivated resource rather thanbeing synthetic. This project serves to investigate what kind of product types are fitting for myceliumcomposites per request from ITG, as well as what kind of surface treatments are possible and fitting tomake the material more desirable. This with the intention of increasing awareness about the material withthe hopes of promoting it to a larger audience, enabling a transition towards more sustainable materialalternatives in the process. With the information gathered through research the project resulted in a sidetable that was designed and manufactured as a 1:1 scale prototype to showcase the possibilities of thematerial. This was done through a material driven design process which was divided into four steps:Understanding the material, Creating materials experience vision, Manifesting materials experience visionand Designing product concepts. Each phase included its own methods respectively and some of themethods include literature review, material testing, benchmarking, user testing, digital prototyping andmanufacturing to name a few. The project is a master thesis for the

Soil is one of the largest ecosystems being ignored by human activities. Our farming practices and urban constructions have contributed to its degradation, with far-reaching consequences for the water cycle’s equi- librium.Reconnect with nature and learn the methods to assist in its recovery are essential for the survival of all inhabitants on this planet. My degree project consists of a large research into the water cycle of urban areas, studying the particular case of Stockholm, that leads to the problems of degraded soil. The aim is to understand the relation- ship between water cycle and soil ecosystems and explore potential solutions. As a result, I have designed KURITA, a learning tool founded upon the ecofeminism values of care, that serves as a learning method for citi- zens to reconnect with soil values and actively participate in its restor- ative process.

Studien är ett designdrivet forskningsprojekt som besvarar frågeställningen: Vilka materiella designkvalitéer finns det i svenskt vildsvinsläder och hur kan dessa appliceras i produktdesign? Frågeställningen undersöks främst genom en material driven designmetod och resultatet analyseras genom teorier om design för hållbar utveckling och design för emotionell varaktighet. Den material drivna designmetoden inleddes med fri utforskning av materialet, första intryck dokumenterades och hypoteser kring materialet dömdes inkorrekta. För att undersöka de tekniska egenskaperna utfördes materialtester. Materialupplevelsen utforskades genom ett metodverktyg där 10 deltagare besvarade frågor kring materialets performativa, sensoriska, affektiva och tolkande egenskaper. Testerna avslutades med en reflektion av materialets positiva, negativa och unika egenskaper. Kunskapen av vildsvinslädrets designkvalitéer används sedan i en idégenerering process för att skapa en hållbar produkt med emotionell varaktighet. Idégenerering mynnar ut i studiens designförslag, en stol med dyna och ryggstöd av vildsvinsläder. Studien avslutas med en slutsats som bekräftar designkvalitéerna i vildsvinläder och en diskussion som belyser insikter som uppkommit under studiens genomförande., The study is a design-driven research project that answers the question: What material design qualities are there in Swedish wild boar leather and how can these be applied in product design? The question is primarily investigated through a material-driven design method and results is analysed through theories of design for sustainable development and design for emotional durability. The material-driven design method began with free exploration of the material, first impressions were documented and hypotheses about the material were deemed incorrect. To investigate the technical characteristics, tests were carried out. The material experience is explored through a tool where 10 participants answered questions about the material's performative, sensory, affective, and interpretive properties. The tests ended with a reflection of the material's positive, negative, and unique properties. The knowledge of the design qualities of wild boar leather was then used in an idea generation process to create a sustainable product with emotional durability. The idea generation culminates in the study's design proposal, a chair with cushion and backrest made of wild boar leather. The study concludes with a conclusion that confirms the design qualities of wild boar leather and a discussion that highlights insights that emerged during the study's implementation.

This graduation project is a part of NEXTSKINS project, within which a novel bacterial cellulose based material encapsulating living bacteria and yeast named Living Therapeutic Skins (LTS) is being developed to sense and treat skin disease such as Atopic Dermatitis(AD). This project serves as a probe in the primitive stage of LTS material development from a design perspective, to explore if livingness as one of the most prominent properties of LTS material can be perceived by people as cureness both physically and emotionally in AD context. This project starts from understanding livingness as material quality and understanding AD and AD patients. Then several design insights are elicited and implemented into design concepts. As the project is situated at a primitive stage of material development, it is decided that the project should focus on the interface level of LTS material and create material and interface variations as discussion triggers with the scientific group, medical experts and end users. As the primary outcomes, we designed and prototyped six variations of skin textures inspired by nature using physical fabrication. Additionally, we created living interfaces that reflect real-time AD conditions, featuring six display patterns corresponding to the different skin textures, as well as environmental factors like temperature and water content through digital simulation. Since the LTS material is still in a semi-finished state, we opted for a gelatin-based hydrogel as a substitute material due to its close resemblance to the LTS material and reusability. Video simulations were used to demonstrate the temporal changes in the living interface in response to external stimuli. Subsequent user studies were conducted to investigate how individuals experience these material variations and living interfaces across sensorial, affective, interpretive, and performative levels. Drawing from the results of the user study, we present a series of spec, Integrated Product Design

This thesis project is a research and design work created for the master’s diploma in Integrated Product Design, TU Delft, aiming to explore the relationship between woven textiles and product design in the context of interior spaces, through the lens of autonomous activation and motion for better living environment. Textiles can acquire shape shifting properties thanks to electronic actuators and other times thanks to the inherent properties of the materials themselves. In this case, using the Material Driven Design methodology, woven textiles were designed to be able to integrate Shape Memory Alloy wires acting as actuators without the use of electric current. The input is the heat from the environment and the output is the shape change and consequently the user’s experience while interacting with the product. Contribution to physical and psychological wellbeing is the ultimate goal of this interaction. The main tool for the exploration of the woven forms was the digital Jacquard TC2 loom which is known in the textile practice as a tool for quick iterations and intricate structures and patterns. After analysing the basic features of the materials through the tinkering process, four concept forms with different textile structures were created. These were tested on technical level to discover the biggest potentials of the system on shape change and on experiential level with user tests to distinguish the material qualities of the textile that promote wellbeing. Considering the findings from both of the studies, new considerations emerged and one final concept was created and manufactured. It represented an autonomous sun shading system to regulate natural light for interiors and thus provide thermal comfort. The project concludes with the final insights about weaving and shape change and any existing limitations and suggestions for further exploration and testing of the product., Integrated Product Design

Each year, 5.9 million tonnes of tea is consumed worldwide. However, this large consumption of tea also leads to large amounts of tea waste. Approximately 90% of steeped tea is being thrown away. This waste leads to problems such as environmental pollution. In order to combat this issue, Tea Clay was previously developed as a material made from wasted tea leaves. However, this material was not suitable for large scale implementation. This project aims to explore the material-based opportunities for Tea Clay to be implemented on a larger scale. The Tea Clay has an envisioned implementation as a memory board game based on tactile and olfactory senses for visually and non-visually impaired people. The Material Driven Design method is used for developing the material further to fit this vision. Benchmarking has inspired the material to have a reprocessing step: creating bulk material that can later be reprocessed into the intended product. Through tinkering, a new material with added gelatine and water was created which can reshape the material once it has been steamed. The reprocessability of the material could benefit the availability of the material for product implementation. Material can be created at one place and sold to customers, who in turn steam the material and reshape it in different products. The reprocessability also facilitates recyclability at the product end of life. Bending tests and hardness tests have shown that it has a similar Young’s modulus and hardness as that of polypropylene and polyethylene, resulting in a material that is suitable for the substitution of conventional plastics. Experiential characterisation tests have proven that users are willing to interact with a novel material with appropriate background information. Knowing the material composition can stimulate them to be more accepting and embracing towards the material. Scent implementation is important for the intended product, as the scent should not disappe, Integrated Product Design

This graduation report covers the process and outcome of developing and designing novel photovoltaic (PV) products for architectural and design applications. The project aimed to find innovative solutions for seamlessly integrating photovoltaics into architecture and design and thus contribute to sustainable building practices. With a hands-on, material-driven approach novel PV customization methods were developed and showcased with a demonstrator. Four concepts were proposed based on PV products made with customization methods that were developed during the project. One of these concepts was worked out into a working prototype. This demonstrated the aesthetic qualities of a novel PV coloring technology. The outcome of Solar Style formed the basis of the continued development and commercialization of PV products., Integrated Product Design

Recently, the construction industry has been confronted with changing regulations, especially with the advent of sustainability goals and circular economy ambitions. The Dutch government wants to accomplish its ambitious initial objective of using 50% fewer primary resources by 2030. Further, by 2050, the goal is to have a waste-free economy that relies mostly on sustainable and renewable resources and reuses both products and raw materials. Steel is a fundamental building component in the construction industry. However, due to changing market and industry conditions like lack of availability of raw materials for the production of virgin steel, exponential rise in prices of virgin steel and production of virgin steel being a high carbon and energy-intensive process - the use of virgin steel is becoming a not feasible option. Therefore, to meet the ambitions of the Dutch circular economy and to comply with the changing regulations like the demonstration of the Environmental Cost Indicator (ECI) as part of the Life Cycle Assessment (LCA) and the introduction of carbon taxes or EU ETS (European Union Emissions Trade System) is forcing the construction industry to limit the adoption of virgin steel. Thus, the reuse of structural steel elements is discussed highly in the building industry as an alternative. However, the reuse of steel encounters several barriers to its implementation. A combination of these barriers results in a paradoxical tension during the decision-making process in the design phase of the project is that “whether is it feasible to first locate existing reclaimed/demountable materials available for reuse from the market and then design around them [Material-Driven Design] or design first with the intention of sourcing/ identifying the required materials later during the procurement phase [Form-Focused Design] ?" The contradictory tension is called the design-acquire paradox. In this research, Biopartner 5, a project which has success, Civil Engineering | Construction Management and Engineering

Material Driven Design, or MDD, is a new way of realizing products starting in the understanding ofthe material rather than the need-driven approach that can be used to describe classic productdevelopment methodology. While new, MDD has potential to encourage more sustainable productsbeing developed and is a useful tool for new designers and engineers to learn. In this paper, the authorpresents some lessons learned from teaching MDD to students in design and product development at aSwedish university. These students have experience from design and product development projects buthave not done material-driven projects before. In general, the author concludes that the students areremarkably well-prepared in terms of tools and knowledge to do MDD, but that course coordination canmake the projects less efficient if this is not solved early on. In master thesis projects or courses withfew in-process deliverables, the implementation seems easier and can give students another path to solveproblems in industry.

Electrochromic materials exhibit a reversible color change that is triggered by an applied voltage. Controlled color change, low voltage operation and the memory effect are three unique material properties defining electrochromic materials. As a result of an electron transfer or redox reaction, the material is able to switch between its bleached (transparent) and colored state. As this color change is a chemical reaction, it only requires an applied voltage to trigger and complete the electron transfer, thus afterwards the applied potential can be removed and the material will stay in its current state; i.e. the memory effect. Electrochromic materials are processed into a sandwich structure of thin layers that enable it to change color when a voltage is applied to it; i.e. an electrochromic device (ECD). An ECD operates through two electrodes that are connected to both the positive and negative of the voltage-source, and the two electrochromic layers. These electrochromic layers are separated by an electrolyte, that allows ion transfer, enabling change of color. Optimizing this layer structure, results into the definition of four stacking sequences, based on their vertical or co-planar stacking sequence (i.e. vertical stacking of the EC layers or merging of both EC layers in the same layer with separated electrodes) combined with the substrate used; conductive and insulating. These four stacking sequences are characterized on their transparency, shape/pattern changing abilities, coloring, design of the images displayed and interaction between the two EC layers; i.e. technical characterization. As result of this material characterization, ‘the puzzle of electrochromism’ is designed. ‘The puzzle of electrochromism is an edge-matching puzzle, with as goal to puzzle four geometric shapes by matching the sides of the adjacent puzzle pieces. Solving this puzzle communicates the goal of the demonstrator (i.e. the technical and experiential characterizations) to the puzzler, Integrated Product Design

The potential and development of mycelium based materials has been increasing over the last years. This material is proving to be a green alternative for a variety of commodity materials like plastics, wood, leather, etc because of its ability to upcycle waste streams. A lot of existing research performed is focussed on the environmental factors required for mycelium cultivation and don’t look beyond these minimal environmental conditions. This graduation project contributes to the development of mycelium based materials by looking beyond the realm of these growing requirements. In this research the effect and potential of acoustic environments on the growth of mycelium is explored according to the Material Driven Design Method by Karana et al. (2015). The goal of this project is to provide first insight into the relation between the acoustic environments and mycelial growth. First by looking into physiology of mycelium and the required growing conditions needed for effective growth of the material. Additionally the physics of sound is explored to get an understanding of the factors that define an acoustic environment. A setup was created to host the required environmental conditions needed by designing three modular incubators. These incubators provide a multifunctional growing chamber where different stimuli systems can be placed precisely within while maintaining the required growing conditions for the mycelium and dampen external sounds. Three different conditions were created for this research, a silence chamber, a mono speaker and a stereo setup to see the response of the mycelium to the different types of stimuli. The response was captured by doing a grayscale analysis to quantitatively analyse the change in growth. In this research the key findings of the research provided first insights into the negative correlation between this acoustic environment and mycelial growth regarding the growth rate and textural qualities at higher volumes. In addition it provid, Design for Interaction

This project explores how 3D printed pneumatic soft actuators can be used to enhance the expressiveness of textiles with alive-like movement. The research begins by studying current literature on shape changing materials and interfaces in order to select the best candidate material to explore during the project. The project then uses a material driven approach to characterize the 3D printed pneumatic textiles for enhancing their performance and ease of fabrication. Based on the characterization, a material concept is created to showcase the material qualities found during the research and to help study the material experience of shape changing interfaces in future research. As a result of the research, we introduce Textalive: The Animated Textile Toolkit, a fully 3D printed approach to explore shape changing interfaces and alive-like expressions including its hardware augmented by the computational tool. The toolkit uses accessible 3D printed pneumatic actuators commonly used in soft robotics due to their controllability and ease of fabrication compared to other shape changing materials. The 3D printed pneumatic actuators can be arranged along a 3D printed textile composite to create a variety of shape morphologies. The hardware allows the user to control the kinetic parameters of the movement of the textile to create different expressions. Additionally, the computational design tool allows the designer to predict the shape and movement of the textile by digitally varying the location of the actuator. The toolkit was validated with various designers ranging from different levels of expertise with smart materials showing its potential as a design tool for easily exploring shape changing interfaces and alive-like expressions., Integrated Product Design

Interwoven refers to material structures made by growing plant roots into man-made patterns. Originally developed as an art piece to demonstrate root intelligence and bring attention to human-nature relations, Interwoven shows the potential to disrupt various commercial industries, especially as textile-based natural fiber reinforcements for composite materials. The artist that created Interwoven, Amsterdam-based Diana Scherer, started a collaboration with the TU Delft Faculty of Industrial Design Engineering to help further develop Interwoven from an art piece to a sustainable material for products design. Following the Material Driven Design method (Karana, et al., 2015), two students have identified materials experience opportunities created by Interwoven materials, the mechanical properties and internal structure of Interwoven are still not fully understood. This study tackles the challenge of performing a technical characterization on Interwoven structures in an effort to correlate processing parameters to its structure, properties, and performance. It is known from past works that Interwoven is fragile and “weak”, but a quantified value for these terms serves as a point of comparison with other materials in the market. To determine these values, a series of tensile tests were performed on grids with a simple square pattern. Dynamic Mechanical Analysis (DMA) tests performed on single roots proved that the amalgamation of roots that make up an Interwoven structure do not efficiently transfer tensile loads since the tensile strength and elastic moduli of Interwoven samples were nearly two orders of magnitude lower than those of a single root. Load transfer between roots was improved through the design of natural fiber-reinforced composites (NFRCs). The (bio)-polymer matrix used for these NFRCs was made up of agar gel, which improved the tensile properties of Interwoven samples, but was still lower than the single root.

Graphene is a two-dimensional carbon based material with unique properties, such as electrical and thermal conductivity. When a textile is coated with graphene, it becomes conductive, while remaining low weight, soft, breathable, flexible, and stretchable. The purpose of this thesis is to investigate what products are suitable to be made with graphene textiles, by using the method Material Driven Design (MDD). Reflections are also made to determine how this method is affected by being applied to a two-dimensional material. To help with this, three kinds of graphene textiles from the company Grafren AB are investigated; conductive textiles, heatable textiles, and textile sensors. The product goal is to develop a portfolio containing 5-8 conceptual products based on these graphene textiles. The process includes conducting an investigation of the technical properties of the material, a user study, and a benchmarking study. This is done to understand the limitations and opportunities of the material, how it is perceived, and what similar materials there are on the market. After that, the material's characteristics are reflected upon to establish a vision for how it should be used in future applications. Then, to follow that vision, a user study is conducted to investigate how people perceive different materials and products, in order to create design guidelines to ensure that the material and product are perceived as intended. Next, concepts are developed according to the previously determined guidelines. To achieve this, idea generating workshops are conducted, where 14 concepts are selected for further development. The portfolio is then created, meant to inspire further usage of the material. It contains the following seven concepts. A heatable textile meant for cooking on camping trips. A fabric containing sensors that can notify when it is damaged. A keyboard made of fabric, for an easy and comfortable use and transportation. A stroller with sensors and heaters, for

Cirkulär ekonomi bygger på principerna om att designa bort avfall, där avfall ses som en råvaruresurs. För att övergå till ett fossilfritt samhälle kommer material från förnyelsebara råvaror att behövas. Biobaserade material har oftast inte samma tekniska egenskaper och estetiska uttryck som befintliga material, biobaserade DIY-material utvecklade från okonventionell råvaruresurs kan väcka starka positiva och negativa reaktioner hos användarna. Studien har undersökt hur man i en Material driven designprocess genom form och kultur kan skapa acceptans för ett biobaserat DIY material från en okonventionell råvaruresurs. Studiens huvudsyfte har varit att bidra med ny kunskap för att underlätta för designers i en Material Driven Designprocess, att identifiera användningsområden och produktform som kan stärka materialacceptans hos användare. Fördjupningsområden i studien är teorier för Hållbar utveckling, Cirkulär ekonomi, Bioekonomi, Material Driven Design for Sustainability och Culture Sensitive Design. Huvudmetoden i studien har varit Material Driven design, vilket innefattas av ett flertal designmetoder. Studien visar på att den kulturella koppling mellan användarna och råvarans ursprung har i denna studie haft en signifikant betydelse för material acceptansen genom att skapa mening för användaren och att materialet primärt behöver applicerat i en produkt på ett sådant sätt att användaren känner tillit till dess prestanda. Resultatet presenteras i form av ett förslag på en användare studie och en produktprototyp., A circular economy is based on the principles of designing away waste, where waste is seen as a raw material resource. To move to a fossil-free society, materials from renewable raw materials will be needed. Bio-based materials usually do not have the same technical characteristics and aesthetic expressions as existing materials, bio-based DIY materials developed from unconventional raw material resources can provoke strong positive and negative reactions among users. This study has investigated how a Material-driven design process through form and culture can create acceptance for a bio-based DIY material from an unconventional raw material resource. The study's main purpose has been to contribute with new knowledge to make it easier for designers in a Material Driven Design process to identify uses and product forms that can strengthen material acceptance among users. In-depth areas in the study are theories for Sustainable Development, Circular Economy, Bioeconomy, Material Driven Design for Sustainability and Culture Sensitive Design. The main method of the study has been Material Driven Design, which is covered by several design methods. The study shows that the cultural link between the users and the origin of the raw material has had a significant impact on material acceptance by creating meaning for the user and that the material primarily needs to be applied in a product in such a way that the user has confidence in its performance. The results are presented in the form of a proposal for a user study and a product concept.

Parkslide är en främmande invasiv växt som ohämmat sprider sig på bekostnad av närliggande vegetation och den biologiska mångfalden. Genom att undersöka möjligheten att ta vara på Parkslides egenskaper och skapa någonting användbart för vårt samhälle, utan negativ påverkan på människa, djur och framtid, så kan det i sin tur skapa en möjlighet för en hållbar utveckling. Ett annat sätt att se på befintligt råmaterial, som en del i en cirkulär ekonomi. Rapporten diskuterar resurs och värde med intention att minska användandet av nya material och byta ut dessa till mer hållbara lösningar.Genom faktainsamling och en materialdriven designprocess utforskas Parkslide som material, vilket resulterar i materialprover som öppnar upp möjligheterna för framtida marknader., Japanese knotweed is an Invasive Alien plant that is widely spread, at the expense of nearby vegetation, which has a negative impact on the biodiversity. By examining the possibilities to use Japanese Knotweed and its characteristics, as something valuable and useful, it can result in opportunities for a sustainable development in the society. We can change the way we view the plant and possibly make it a part of a circular economy. This work will discuss resource and value with the intention to reduce the use of new materials and switch those to a more sustainable solution.Through literature studies, interviews, survey and a Material Driven Design process I will explore Japanese Knotweed as a material, which results in material samples and discussion. This opens up the possibilities for future markets.

The recent academic literature on material practices within design has revealed the emergence of a new design discipline, DIY-materials or material design. Designers educated in DIY-materials and the Material Driven Design method, applied in design courses in major European universities are beginning to identify themselves as material designers. This paper presents a qualitative case study of the challenges faced by material designers and design students developing DIY-materials from the stage of a small sample with promising experiential qualities and technical properties, towards a more viable material. A comparative case study of twenty-eight material driven design projects and four explorative semi-structured interviews were conducted with designers. The result suggest: (a) that designers have a tendency to focus more on the experiential attributes and aesthetical qualities rather than the technical attributes in the early stages of material development, (b) projects that are situated in specific contexts or systems have a higher success rate, (c) bio-based DIY-materials are in general sensitive to moist and high temperatures, (d) a systematic approach during tinkering combined with analytic skills are crucial for the development of DIY-materials. In this paper we also build on our previous research, regarding the development of reflective material practices for design students in higher education. It is hoped that this research can contribute to the further development of material design as a new design discipline., Awarded Best presentation

Varje år produceras mer än 10 miljoner ton kaffe i världen (www.ico.org) och Sverige är världens näst störst kaffedrickande nation med ca 80 ton kaffe på år, vilket motsvarar i snitt 3,5 koppar kaffe per person dagligen (www.kaffeinformation.se). Med en stor produktion tillkommer också en stor mängd avfall. När kaffebönor rostas får man ett restmaterial av kaffebönans skall, så kallad kaffechaff. I denna studie undersöks om detta spillmaterial vid kafferosterier kan få ett mervärde genom material driven design. Syftet är att minska avfall och skapa ett nytt material. Arbetet rör sig i områdena materialitet och hållbar utveckling och metod används Material Driven Design method (Karana et al., 2015) samt Material Driven Design for Sustainability (Bak-Andersen, 2018). Resultatet blev tre olika biologiskt nedbrytbara material, bland annat ett som kan användas som till engångsartiklar eller förpackningsmaterial. Studien visar på möjligheter att ge mervärde på restprodukter inom kafferosteri och skulle kunna användas som möjligt underlag till att se om spill från andra industrier skulle kunna få ett mervärde., Every year, more than 10 million tonnes of coffee are produced in the world (www.ico.org) and Sweden is the world’s second largest coffee drinking nation with about 80 tonnes of coffee a year, which corresponds to an average of 3.5 cups of coffee per person daily (www.kaffeinformation.se). With a large production there is also a large amount of waste. When coffee beans are roasted, you get a residual material from the coffee bean shell, so-called coffee chaff. In this study, this waste material are investigate whether it can get added value through material driven design. The purpose is to reduce waste and create new material. The work moves in the areas of materiality and sustainable development, and the method is the Material Driven Design method (Karana et al., 2015) and Material Driven Design for Sustainability (Bak-Andersen, 2018). The result was three biodegradable materials, including one that can be used as a disposable or packaging material. The study shows opportunities to add value to residual products within coffee roasters and could be used as a possible basis to see if waste from other industries could gain added value.

Blåmusslor livnär sig på att filtrera vatten på alger och partiklar, som i sin tur tagit upp kväve och fosfor. Genom odling, skörd och effektiv användning av musslorna kan man hjälpa till att minska närsaltsbelastning och övergödning i Öresund. Syftet med denna studie har varit att undersöka möjligheterna att använda en materialdriven designprocess för framtagning av material för en cirkulär ekonomi genom att tillämpa råmaterialet musslor. Fördjupningsområden i studien har varit att studera teorier kring design för hållbar utveckling, cirkulär ekonomi och materialdriven design. Genom en materialdriven designprocess har ett biologiskt nedbrytbart materialet tagits fram som har potential att ingå i en cirkulär ekonomi. Resultatet av materialframtagningen presenteras i form av ett materialkoncept som representerar materialets tekniska och sensoriska egenskaper., Mussels feed on filtering water on algae and particles, which in turn have absorbed nitrogen and phosphorus. By cultivating, harvesting and efficient use of the mussels, you can help reduce eutrophication in the Sound. The purpose of this study has been to investigate the possibilities of using material driven design processes for creating new materials, for a circular economy by applying the raw material mussels. The main areas of study have been theories within design for sustainable development, circular economics and material driven design. Through a material driven design process, a biodegradable material has been developed that has the potential to be part of a circular economy. The result of the material development is presented in the form of a material concept that represents the technical and sensorial properties of the material.

Vi behöver minska vår materialkonsumtion, idag gör vi av med mer resurser än vad vi har tillgång till. I den här studien har först en materialkonstruktion tagits fram och därefter ett produktkoncept för konstruktionen. För att ta fram materialkonstruktionen har biomimicry använts. Biomimicry är designmetoder för att lösa designproblem med inspiration från naturen. Naturen använder sig av så lite material som möjligt. Materialkonstruktionen är inspirerad av växtceller. Konstruktionen har två hierarkier som går i två olika riktningar, en riktning som går längs med och en riktning som går i djupled.För att hitta ett produktkoncept för materialkonstruktionen har material driven design (MDD) använts. MDD är en experimentell metod för att lära känna ett material och förstå dess användningsområde. Produktkonceptet är en stapelbar pall.För att minska på resurser används 3d-printning. 3d-printning är en additiv teknik och minskar på så sätt materialåtgång. Dessutom kan allt material lätt återanvändas eftersom det bara behövs ett material.Produkten kan produceras lokalt vilket minskar på transporter. PLA har använts som material i den här studien., We need to reduce our material consumption, today we are wasting more resources than we have access to. In this study, a material construction was first developed and then a product concept for the construction. Biomimicry has been used to develop the material construction. Biomimicry are design methods for solving design problems with inspiration from nature. Nature uses as little material as possible. The material construction is inspired by plant cells. The construction has two hierarchies that go in two different directions.To find a product concept for the construction, material driven design (MDD) has been used. MDD is an experimental method used to get to know a material and understand its application. The product concept is a stackable pallet.To reduce resources, 3D printing is used. 3D printing is an additive technology and thus reduces material consumption. In addition, all material can be easily reused as only one material is needed.The product can be produced locally, which reduces on transport. PLA has been used as material in this study.

Integrating living organisms in design could offer alternative and more sustainable ways of producing and using products. The use of bioluminescent organisms in design is a relatively new and unknown subject. Because of this, interested designers have a lot of homework to do before starting the actual design process. Successfully changing the organisms habitat from nature to a user’s home and provoking the desired luminescence depends on specific biological and environmental requirements. The aim of this graduation project is to provide interested designers with guidelines on the cultivation and perpetuation of bioluminescent organisms when integrated into a consumer product. The first step is to gather information on two bioluminescent organisms, P. fusiformis and P. phosphoreum, in an extensive literature research. This results in design insights which compare both organisms on the challenges and potential when integrated in a consumer product. The second step continues with the most promising organism, P. phosphoreum. This organism is used within experiments further researching the bioluminescent and perpetuation characteristics, relating them to usage and storage possibilities. The experiment results are translated into design insights. The third step is to combine the design insights from both the literature research and the conducted experiments into guidelines which will help and inspire interested designers in the creation of products with integrated bioluminescent organisms. The guidelines are applied within a future scenario which will act as an example on how P. phosphoreum could be integrated within a design., Integrated Product Design

This graduation project follows the process of researching, developing and creating a demonstrator for a surface design using the electroluminescent material - EL for short - a sandwich structured composite that emits light when alternating current flows through it. The project kicks-off with an analysis phase where the electroluminescent material and relevant client products are introduced. This includes a detailed description of the EL material from working principle to pre-fabricated versions possible to purchase from online stores. Next the EL materials themselves and A+N products were tinkered with. New DIY techniques are introduced which can help to create quick prototypes. This phase also was helped by three searches: experiential characterisation, luminescence measurement and connecting a sample to an oscilloscope to see how frequency affects the colour output. The surface design phase started with rapid prototyping ideas; a few selected ones were iterated on and turned into phosphor covered models that light up under UV light. The chosen concept direction is a set of twisted stripe designs that can be organised into a large pattern on a wall. The concept development started with creating all the elements of the tile set and some possible large patterns. During a long iteration phase the final version of the concept - a simple tile set with two different twist designs was developed. The last chapter describes the production of the demonstrators; the making of the EL sheets and then the assembly steps. The chapter introduces the final design - the LUX TWIST tile site. The LUX Twist Tile set is a modular surface installation that uses electroluminescent (EL) material to create an illuminated 3D pattern on a wall. The base module is a tile with twisted electroluminescent strips on it. The set consists of different tile designs, the featured twist comes in a curved and a straight option, available in left and right orientations. An empty tile is also part of the

Within this graduation project, the qualities and potential of bioluminescent micro-algae will be explored with the use of the Material Driven Design Method, as described by Karana et al.(2015). This project aims to provide designers first insights in the behaviour of the bioluminescent algae by looking at the relation between movement and light. The first step will be to understand the different factors that influence the growth of the organisms, in order to be able to create a sustainable living environment that allows us to effectively maintain and grow the organisms. Afterwards, reflecting upon the growing process and creating general guidelines for effectively growing material. Next, the response of the material in regards to different types of stimuli was explored and three types of agitation forms (rotation, pulse and vibration) were evaluated; providing first insights in how the type of stimuli affects the characteristics of the light, with a focus on changes in total light output over time, differences in experiential qualities and boundaries of the material. Based upon the questions that resulted from the exploration phase, a research structure was defined. Within the research, key insight in the flash characteristics and overall behaviour of the light, with regards the temporal form, textural qualities and spatial distribution of the light, will be analysed; taking the first steps in describing the complex relation between movement and experiential qualities of the light. In the end, providing an overview of factors that can be adjusted to alter the flash characteristics and general behaviour of the light. The project is concluded with the design of a research object, in the form of a small scale interactive exhibition; displaying the findings of the research phase and sparking the interest of other designers; stimulating further research and promoting the use of bioluminescent materials., Design for Interaction

Previous research proved the potential of using mussel shell waste as additive manufacturing (AM) material. In this thesis, mussel shell powder was combined with sodium alginate, since it allows reversible cross-linking. Due to reversible cross-linking, this water-soluble and recyclable material can temporarily be made water-resistant, so it can be used for applications that need to be water-resistant. In this thesis, this material was researched, improved, and eventually used to print a prototype of a parametrically designed plant-specific planter., Integrated Product Design

While petroleum-based polymers have been widely accepted due to their functional properties, it is becoming evident that some bio-based materials can also be engineered to deliver novel functionalities such as 4D responsivity. Integrating bio-based responsive materials with 4D printing technology can offer considerable potential for large-scale applications such as furniture products. This integration provides a more novel form of transportation for such products as well as the opportunity to eliminate the requirement for the production of multiple parts and assembly of them. In addition, this integration provides the opportunity to make use of locally-available resources for a more sustainable economy. Despite these advantages, there is a lack of research that explores the application of these materials and technologies for large-scale products. In response, this research showcases the potential design opportunity of responsive bio-based polymers combined with 4D printing technology for large-scale applications. This research involves a series of physical experiments conducted in collaboration with material scientists based on the Material Driven Design method. These experiments demonstrate the novel properties of engineered cellulose-based polyesters in the form of design concepts. Hardware was developed to provide the required tools for large-scale prototyping. In addition, this research employs the Research Through Design approach to guide an experimental and iterative process of developing furniture designs, as a case study for large-scale products. This research creates four outcomes in different stages of the project. The first outcome is a taxonomy of cellulose-based polyesters with their properties. The second outcome is a large-scale paste extruder that can be installed on an industrial robot arm. The third is a series of 4D-printed, small-scale furniture models with the ability to transform from a 2D to 3D shape for flat-pack furniture. Lastly, this resea
