Additive manufacturing (AM) is one of the technologies of Industry 4.0 that has been contributing to the development of different manufacturing industries. The integration of sustainability concepts into additive manufacturing has been gaining attention among researchers. This integration is essential in the development of AM technologies and can be a significant asset in terms of decision making for organizations. This work aims to present a concise literature review on the integration of decision making, especially multi-criteria decision making, and sustainability into the AM environment. The literature on this topic currently possesses a total of fifteen documents, which were analyzed in this work. Some developments on this topic have been achieved in domains such as material selection, process selection and challenges, and drivers' analysis of sustainable AM. This review shows that even though there has been an effort in recent years to integrate sustainability into additive manufacturing, there is still a long road to the development of this topic for the future, and so some recommendations for future research paths are presented.

Funding Information: João Pedro Oliveira acknowledges funding by national funds from FCT - Fundação para a Ciência e a Tecnologia , I.P., in the scope of the projects LA/P/0037/2020 of the Associate Laboratory Institute of Nanostructures, Nanomodelling and Nanofabrication – i3N. This activity has received funding from the European Institute of Innovation and Technology (EIT) – Project Smart WAAM: Microstructural Engineering and Integrated Non-Destructive Testing. This body of the European Union receives support from the European Union’s Horizon 2020 research and innovation programme . Publisher Copyright: © 2023 The Authors The industrial progress made throughout these years has led to great results in terms of producing fast and with good quality. However, the impacts related to that production, whether these are environmental, economic, or social have been, at times, neglected. The manufacturing sector, as one of the most polluting sector, felt the urge to adapt to this industrial progress and find ways to produce with improved sustainability goals without compromising the quality of the final product and the production time. Industry easily understood the benefits of this greener approach, and, with this, new sustainable technologies started to emerge. Additive Manufacturing (AM) is one of those technologies that provide alternative sustainable paths to traditional manufacturing. In order to generalize the benefits of AM production in terms of sustainability, when compared to traditional processes, further investigations must be conducted. In this sense, the proposed work has the intention of finding the environmental impacts associated with a particular AM technique for the fabrication of metal parts, Wire Arc Additive Manufacturing (WAAM). A practical work based on the production of three different complexity metal parts considering an additive (WAAM) and a subtractive (Computer Numerical Control (CNC) Milling) manufacturing process is developed. To quantify the environmental impacts of both processes, the author resorts to the Life Cycle Assessment (LCA) methodology. The assessment is conducted in the SimaPro 9.2 software, accordingly to ISO 14044:2006 standard. The results allow a comparison between both types of manufacturing and enable the suggestion of measures to decrease the environmental footprint of WAAM. It was found that WAAM approach leads to a material saving ranging between 40% and 70% and an environmental impact reduction in the range of 12%–47%, compared to the subtractive approach for fabricating the 3 geometries considered in this study. The conclusions obtained are specific to this particular application and, once more, it is acknowledged that in order to reach a global understanding relative to this technology's environmental implications, extra research still needs to be made. publishersversion published

Funding Information: Inês Ferreira acknowledges financial support from Fundação para a Ciência e Tecnologia for funding PhD Grant - REF: SFRH/BD/145448/2019. Helena Carvalho and Radu Godina acknowledge Fundação para a Ciência e a Tecnologia (FCT - MCTES) for its financial support via the project UIDB/00667/2020 (UNIDEMI). Publisher Copyright: © 2022 The Authors The role of new technologies such as additive manufacturing and blockchain technology in designing and implementing circular economy ecosystems is not a trivial issue. This study aimed to understand if blockchain technology can be an enabler tool for developing additive symbiotic networks. A real case study was developed regarding a circular economy ecosystem in which a fused granular fabrication 3D printer is used to valorize polycarbonate waste. The industrial symbiosis network comprised four stakeholders: a manufacturing company that produces polycarbonate waste, a municipality service responsible for the city waste management, a start-up holding the 3D printer, and a non-profit store. It was identified a set of six requirements to adopt the blockchain technology in an additive symbiotic network, bearing in mind the need to have a database to keep track of the properties of the input material for the 3D printer during the exchanges, in addition to the inexistence of mechanisms of trust or cooperation between well-established industries and the additive manufacturing industry. The findings suggested a permissioned blockchain to support the implementation of the additive symbiotic network, namely, to enable the physical transactions (quantity and quality of waste material PC sheets) and monitoring and reporting (additive manufacturing technology knowledge and final product's quantity and price). Future research venues include developing blockchain-based systems that enhance the development of additive symbiotic networks. publishersversion published

Given the current environmental concerns related to manufacturing, the introduction to the industrial symbiosis concept brought purpose to waste, instead of disposing it in landfills or eliminating it through incineration. The waste generated by industrial processes, or end-of-life products, is redirected to be used as a “new” input in another process by one or more organizations, which is a mutual benefit or a “symbiosis”. Despite its relevancy, the industrial symbiosis concept is marginally explored in the context of additive manufacturing; this emerging technology has disruptive potential regarding the use of different materials as secondary raw materials. This paper presents a systematic literature review regarding industrial symbiosis and additive manufacturing. The main objective is to identify how wastes can be used as input materials to additive manufacturing processes and what exchanges of resources occur in an industrial symbiosis setting. A final sample of 32 documents was reached and analyzed. Five examples of using waste streams in additive manufacturing processes to produce goods were highlighted and explored. publishersversion published

Today's business setting is becoming increasingly dynamic and characterised by various technological advancements. Knowledge, as well as how it is shared and preserved inside the organisations, has become a volatile active source of competitive advantage. As a result, instruments to assist organisations in managing their knowledge and leveraging value generation are required. Knowledge management processes are even more critical for companies that use or can use Additive Manufacturing Technology (AM), which is frequently linked to 3D printing, because they are in a disruptive and emergent industry, which utilises innovative and complex products, whose business models' dynamic is still unknown. Although the tremendous potential that is presented by this technology, there are still many concerns about its future advancements and implications on society and business models. This paper aims to answer the question: What are the impacts of the adoption of AM technology on companies' business models? Moreover, to answer the question of what knowledge management strategies can be adopted to increase the competitiveness and sustainability in the business models, in companies using AM technology? To achieve the objectives, a literature review was performed. The results demonstrated that the disruptions created by technology are not yet known to many companies. Similarly, knowledge of the impacts on business models and other elements of sustainability is limited. In terms of originality, the goal of this research is to contribute to and encourage data-driven debates about the potential implications of AM adoption on knowledge management strategies.

Additive Manufacturing (AM) is viewed as a disruptive technology with the potential to replace many manufacturing processes. With its rapid proliferation in recent years, it is crucial to understand how to measure this technology's social impacts. There are many studies available in the existing literature regarding the economic and environmental impacts of AM technology. However, research regarding the social impacts of this technology is still scarce. To this end, this research has developed a framework based on Social Life Cycle Assessment (SLCA) methodology to measure AM products' social impacts throughout their life cycle stages. The proposed framework includes an underlying mathematical model that was developed to allow for the aggregation of indicator scores. Additionally, cut-off scores were determined to differentiate between positive and negative social impacts. This framework can be applied to case studies, which provides a final score that quantifies the social impacts of an AM product throughout all its life cycle stages. It also provides scores for each stakeholder category and life cycle stage, which facilitates the identification of hotspots that require attention from organizations. [ABSTRACT FROM AUTHOR]

KNOWLEDGE management , *THREE-dimensional printing , *BUSINESS models , *COMPETITIVE advantage in business , *TECHNOLOGICAL innovations , *VALUE creation - Abstract
In the current business environment with increasingly dynamic and with numerous technological innovations, human resources and the generated know-how are volatile. Knowledge and the way it is shared and retained in organizations has become a source of competitive advantage. It is, therefore, necessary to develop tools to help companies manage their knowledge and use it to leverage value creation. In the case of companies that use or can use additive manufacturing technology, often associated with 3D printing, knowledge management processes are even more important since they are part of a disruptive and emerging industry with innovative and complex products whose business models' dynamics is not yet fully understood. Despite the great opportunities that this technology could provide, the uncertainties concerning its future developments and impacts on business models still remain. The goal of this literature review study is to get insights into publications that relate Additive Manufacturing Technology and Knowledge Management. The method used in this study is based on the analysis of all the data obtained from ISI Web of Science and Scopus. In terms of originality, this study aims to contribute and stimulate data-driven discussions regarding the possible impacts of the adoption of additive manufacturing regarding knowledge management strategies.

- Abstract
Additive manufacturing has the potential to make a longstanding impact on the manufacturing world and is a core element of the Fourth Industrial Revolution. Additive manufacturing signifies a new disruptive path on how we will produce parts and products. Several studies suggest this technology could foster sustainability into manufacturing systems based on its potential of optimizing material consumption, creating new shapes, customizing designs and shortening production times that, all combined, will greatly transform some of the existing business models. Although it requires reaching a certain level of design maturity to completely insert this technology in an industrial setting, additive manufacturing has the potential to favorably impact the manufacturing sector by reducing costs in production, logistics, inventories, and in the development and industrialization of a new product. The transformation of the industry and the acceleration of the adopting rate of new technologies is driving organizational strategy. Thus, through the lenses of Industry 4.0 and its technological concepts, this paper aims to contribute to the knowledge about the impacts of additive manufacturing technology on sustainable business models. This aim is accomplished through a proposed framework, as well as the models and scales that can be used to determine these impacts. The effects are assessed by taking into account the social, environmental and economic impacts of additive manufacturing on business models and for all these three dimensions a balanced scorecard structure is proposed.

- Abstract
Additive manufacturing (AM) is a group of technologies that create objects by adding material layer upon layer, in precise geometric shapes. They are amongst the most disruptive technologies nowadays, potentially changing value chains from the design process to the end-of-life, providing significant advantages over traditional manufacturing processes in terms of flexibility in design and production and waste minimization. Nevertheless, sustainability assessment should also be included in the research agenda as these technologies affect the People, the Planet and the Profit: the three-bottom line (3BL) assessment framework. Moreover, AM sustainability depends on each product and context that strengthens the need for its assessment through the 3BL framework. This paper explores the literature on AM sustainability, and the results are mapped in a framework aiming to support comprehensive assessments of the AM impacts in the 3BL dimensions by companies and researchers. To sustain the coherence of boundaries, three life cycle methods are proposed, each one for a specific dimension of the 3BL analysis, and two illustrative case studies are shown to exemplify the model.

- Abstract
Despite the myriad of possibilities and applications of additive manufacturing (AM) technology, knowledge about the social impacts of this technology is very scarce and very limited in some areas. This paper explores how factors generated by the development of AM technology may create social impacts, affecting the health and social well-being of people, quality of life, working conditions, and the creation of wealth. This paper presents the results of an exploratory multiple case study conducted among four Portuguese organizations that use AM technology, aiming to determine their perceptions regarding the social impacts of AM, its effects, and causes. The results confirm that AM technology is mainly seen to create positive impacts on health and safety (regarding physical hazards), on expectations for the future, on leisure and recreation, on low disruption with the local economy, on economic prosperity, on the professional status, and on innovative employment types. Nevertheless, a negative impact was also found on health and safety (concerning hazardous substances), as well as several mixed and null impacts. The main limitations of the research arise from the use of a case study methodology, since the results can be influenced by contextual factors, such as the size of the organizations in the sample, and/or social, cultural, technological, political, economic, and ecological factors. This study gives an up-to-date contribution to the topic of AM social impacts and social changes, an area which is still little-explored in the literature. [ABSTRACT FROM AUTHOR]

The industrial progress made throughout these years, allowed to obtain great results in terms of producing fast and with good quality. However, the impacts related to that production, whether these are environmental, economic, or social have been, at times, neglected. The manufacturing sector, as one of the most pollutants, felt the urge to adapt to this industrial progress and find ways to produce with a greener mentality without compromising the quality of the final product and the production time. The industry easily understood that they could only benefit from this approach, given the fact that a greener mentality involves a series of factors that limit the need for reinvestments. Society itself has also become more environmental aware and stricter environmental legislations have been created. Consumers started prioritizing greener products and sustainable productions that comply with those legislations. With this in mind, new sustainable technologies emerge and improvements to the technol- ogies that already exist are made. Additive Manufacturing (AM) is one of the revolutionary technologies that provides alternative and more sustainable paths to the traditional manufacturing. The proposed work has the intent of recognizing the environmental impacts associated with a particular AM technique for the fabrication of metal parts, the Wire Arc Additive Manufacturing (WAAM). Firstly, a global overview on AM processes is made. Afterwards, WAAM is analyzed with further detail identifying, through literature, the main challenges underlying. In order to validate some of these chal- lenges found, three case studies were conducted considering the Life Cycle Assessment (LCA) method- ology. The practical work was based on the production of different complexity metal parts considering an AM process and, for greater context on the subsequent results, a subtractive manufacturing process. The quantification of the environmental impacts not only allowed a comparison between both types of manufacturing but also enabled the identification of the main environmental hotspots and conse- quently the suggestion of measures to decrease the impacts related to them. The results were obtained for this particular application and it is acknowledged that in order to reach a global understanding rel- ative to this technology's environmental implications, extra research still needs to be made. Os progressos industriais realizados ao longo destes anos, permitiram obter grandes resultados em termos de uma produção rápida e de boa qualidade. Contudo, os impactes relacionados com essa produção, sejam estes ambientais, económicos ou sociais, têm sido, por vezes, negligenciados. O sector industrial, como um dos mais poluentes, sentiu a necessidade de se adaptar a estes progressos indus- triais e encontrar formas de produzir incorporando uma mentalidade mais verde sem comprometer a qualidade do produto final e o tempo de produção. A indústria facilmente compreendeu que só poderia beneficiar desta abordagem, visto que uma mentalidade mais verde está relacionada com uma série de fatores que restringem a necessidade de reinvestimentos. A própria sociedade também se tornou mais ambientalmente consciente e criadas le- gislações ambientais mais rigorosas. Os consumidores começaram a dar prioridade a produtos mais ecológicos e a produções que cumprissem essas mesmas legislações. Com estes progressos surgiram novas tecnologias sustentáveis e as tecnologias já existentes foram melhoradas. O fabrico aditivo (FA) é uma das tecnologias revolucionárias que proporciona caminhos alternativos e mais sustentáveis para o fabrico tradicional. O trabalho proposto tem a intenção de reconhecer os impactes ambientais associados a uma técnica de FA particular, o Fabrico Aditivo através de Arco Elétrico. Em primeiro lugar, é dada uma visão geral acerca dos processos de FA. Posteriormente, o Fabrico Aditivo através de Arco Elétrico é analisado com mais detalhe e, através da literatura, são identificados os principais desafios que lhe estão subja- centes. Com o intuito de validar alguns destes desafios encontrados, foram realizados três estudos de caso considerando a metodologia de Avaliação do Ciclo de Vida (ACV). O trabalho prático baseou-se na produção de diferentes peças metálicas, considerando um processo de fabrico aditivo e, de modo a se conseguir contextualizar os resultados obtidos, um processo de fabrico subtrativo. A quantificação dos impactes ambientais permitiu, não só comparação entre ambos os tipos de fabrico como também per- mitiu a identificação dos principais pontos críticos ambientais e, consequentemente, a sugestão de me- didas para diminuir os impactos relacionados com os mesmos. É de ressalvar que, os resultados foram obtidos para esta aplicação específica e reconhece-se que para se chegar a um entendimento global relativamente às implicações ambientais desta tecnologia são necessários mais desenvolvimentos.
