This book summarizes recent advances in robotics using 3D printers and rapid prototyping as a concept development tool. The book is focused on industrial applications, educational aspects, rehabilitation, and other related topics. In particular, the book is intended to offer the reader a smooth yet deep introduction to the use of 3D printers and rapid prototyping techniques as a solution to robotics and mechatronics problems, highlighting successful case studies.

Since the publication of the first edition, several Additive Manufacturing technologies have been invented, and many new terminologies have been formalized. Each chapter has been brought up-to-date so that this book continues with its coverage of engineering procedures and the application of modern prototyping technologies, such as Additive Manufacturing (AM) and Virtual Prototyping (VP) that quickly develops new products with lower costs and higher quality. The examples, practice exercises, and case studies have also been updated.Features Gears toward rapid product prototyping technologies Presents a wide spectrum of prototyping tools and state-of-the-art additive manufacturing technologies Explains how to use these rapid product prototyping tools in the development of products Includes examples and case studies from the industry Provides exercises in each chapter along with solutions

This book describes a novel system for the simultaneous visual and tactile rendering of product shapes which allows designers to simultaneously touch and see new product shapes during the conceptual phase of product development. This system offers important advantages, including potential cost and time savings, compared with the standard product design process in which digital 3D models and physical prototypes are often repeatedly modified until an optimal design is achieved. The system consists of a tactile display that is able to represent, within a real environment, the shape of a product. Designers can explore the rendered surface by touching curves lying on the product shape, selecting those curves that can be considered style features and evaluating their aesthetic quality. In order to physically represent these selected curves, a flexible surface is modeled by means of servo-actuated modules controlling a physical deforming strip. The tactile display is designed so as to be portable, low cost, modular, and high performing in terms of the types of shape that it can represent.

Since the dawn of civilization, mankind has been engaged in the conception and manufacture of discrete products to serve the functional needs of local customers and the tools (technology) needed by other craftsmen. In fact, much of the progress in civilization can be attributed to progress in discrete product manufacture. The functionality of a discrete object depends on two entities: form, and material composition. For instance, the aesthetic appearance of a sculpture depends upon its form whereas its durability depends upon the material composition. An ideal manufacturing process is one that is able to automatically generate any form (freeform) in any material. However, unfortunately, most traditional manufacturing processes are severely constrained on all these counts. There are three basic ways of creating form: conservative, subtractive, and additive. In the first approach, we take a material and apply the needed forces to deform it to the required shape, without either adding or removing material, i. e., we conserve material. Many industrial processes such as forging, casting, sheet metal forming and extrusion emulate this approach. A problem with many of these approaches is that they focus on form generation without explicitly providing any means for controlling material composition. In fact, even form is not created directly. They merely duplicate the external form embedded in external tooling such as dies and molds and the internal form embedded in cores, etc. Till recently, we have had to resort to the'subtractive'approach to create the form of the tooling.

At first glance, a book on'Design by Composition for Rapid Prototyping'may seem out of place in a series on Robotics. However, this work has a couple of strong connections to the field of robotics and the robotics community, and I am delighted to introduce it to the series. The first connection is the motivation behind Binnard's work. Michael Binnard came to Stanford after having done his Masters thesis at the M.LT. Artificial Intelligence Lab, where he designed and built small walking robots, such as Boadicea (http://www.ai.mit.eduJprojects/boadicea/).At M.LT. he observed first-hand how difficult it is to align, connect and support standard actuators, sensors, and processors in small mobile robots. Figure lea) below shows how complicated it is just to connect a simple motor to one link of a robot leg using conventional methods. Surely there had to be a better way! Shape deposition manufacturing, an emerging rapid prototyping process, offered a possible solution. Actuators, sensors, processors and other components could be embedded directly into almost arbitrary three-dimensional shapes, without any of the fasteners and couplings that complicate the design in Figure lea). The process makes it possible to construct integrated robotic mechanisms, such as the example shown in Figure 1 (b) and the additional examples found in Chapters 7 and 8 of this monograph.

More quality, more flexibility, and less costs seem to be the key to meeting the demands of the global marketplace. The secret to success in this arena lies in the expert execution of the critical tasks in the product definition stage. Prototyping is an essential part of this stage, yet can be very expensive. It must be planned well and use state-o

We are especially pleased to present our edited book in an area that is quickly emerging as one of the most active research areas that integrate both engineering and medicine. Preliminary research results show signi?cant potential in effecting major breakthroughsranging from a reduction in the number of corrective surgeries needed to the ‘scienti?c miracle'of generating tissue growth. Over $600 million has been in invested in tissue engineering last year alone—a large and signi?cant component of this is in the area of virtual and physical prototyping. Virtual & Physical prototyping can broadly be divided into three categories: Modeling, Manufacturing& Materials. This book focuses on the?rst part and some areas of the second.The second bookin this series will focuson the areas in the s- ondandthird categories.As youwill see fromthis book,the principlesutilizeddraw heavily from the more traditional engineering?elds including mechanical engine- ing, industrial engineering, civil engineering (structures), electrical engineering and bio engineering. The?rst chapter by Winder provides an insight into the practicalities of creating custom made implants for the skull details. The concept of cranioplasty, describing the correction of a bone defect or deformity in the cranium using a bio-compatible material, is described and explored from a computational point of view In Chapter 2, Ming Leu and his group of researchers review the use of virtual reality technology for the development of a virtual bone surgery system, which can be used for training in orthopedic surgery and planning of bone surgery procedures.

„Wenn wir Schlittschuh über dünnes Eis laufen, liegt unser Heil nur in der Schnelligkeit.“ meinte Ralph Waldo Emerson (1803 82), amerikanischer Philosoph und Dichter. Innovationsorientierte Unternehmen müssen in der Lage sein zu beschleunigen, wenn es drauf ankommt. Sie müssen „die Na se vorn haben“ mit Erfolg versprechenden Neuerungen, um die Konkur renz auf dem überlasteten Eis förmlich stehen zu lassen. Wie sieht das Umfeld in der Forschung und Entwicklung heutzutage aus? Zeit und Kostendruck, eine stark differenzierte Markt bzw. Kun denorientierung, sowie steigende Qualitätsanforderungen sowohl bei den Produkten wie auch den zugehörigen Prozessen bilden herausfordernde und treibende Rahmenbedingungen. Innovationen müssen in diesem turbu lenten und komplexen Umfeld nicht nur zielgerichtet und Ressourcen schonend sondern auch schnell und effizient entwickelt werden. „Wer auf dünnem Eis verharrt, kann schnell einbrechen.“ „Entwicklung und Erprobung innovativer Produkte – Rapid Prototy ping“ ist die Zielsetzung des von der DFG geförderten Sonderforschungs bereichs 374, dessen Ergebnisse in diesem Band beschrieben werden.
