In this paper, we examine the designs and motivations for assistive technology found on Thingiverse.com, the largest of these communities at the time of this writing. We present results from a survey of all assistive technology that has been posted to Thingiverse since 2008 and a questionnaire distributed to the designers exploring their relationship with assistive technology and the motivation for creating these designs. The majority of these designs are intended to be manufactured on a 3D printer and include assistive devices and modifications for individuals with disabilities, older adults, and medication management. Many of these designs are created by the end-users themselves or on behalf of friends and loved ones. These designers frequently have no formal training or expertise in the creation of assistive technology. This paper discusses trends within this community as well as future opportunities and challenges. Figure 1.

  • Cultures of Sharing in 3D Printing: What Can We Learn from the Licence Choices of Thingiverse Users?
    Cultures of sharing in 3D printing: what can we learn from the licence choices of Thingiverse users? 1. Introduction A growing literature in economics and social science has explored the practices of information exchange among online communities. A strong theme within this literature is that open cultures – characterised by reciprocal sharing, weak IP, and open flows of information among practitioners – are conducive to technological innovation. In Benkler’s influential analysis, the end result is “a flourishing nonmarket sector of information, knowledge, and cultural production… subject to an increasingly robust ethic of open sharing, open for all others to build on, extend, and make their own” (2006, p.7). This phenomenon has been the focus of much recent research on collaborative production models, covering a range of topics including wikis, open- access publishing, free software and open science (e.g. Nielson 2011, Suber 2012, Anderson 2012, Hatch 2013, Phelps 2013). One lesson from this literature is that sharing practices are context-dependent. Sharing is a social practice shaped by a range of variables, and sharing practices differ from community to community and from technology to technology (Kennedy 2013). Infrastructural issues, cultural factors and legal frameworks, both explicit and implicit, play a role in shaping the context in which collaboration occurs. It is therefore necessary to understand the norms, values, structures and systems that emerge around particular forms of practice. Scholars in various disciplines have taken up this challenge by documenting the specific (rather than universal) aspects of sharing practice, such as the regulatory frameworks that govern conduct and the variable properties of technological platforms (e.g.

INTRODUCTION An aspiration of scientists and inventors, a darling of ‘Trekkies,’ Star Trek’s replicator is one of television’s great fictional ideas. First appearing in the late 1980s on Star Trek: The Next Generation, the replicator was a fictional device that could reproduce any food, liquid, or object its user wanted.1 Twenty years ago, the technology to create a tool out of thin air to fix a space station seemed like a possibility only on the silver screen. Today, the possibility of Star Trek’s replicator doesn’t seem so distant. In fact, NASA plans to roll out the first attempt at approaching the wonders of that technology for use on the final frontier in the near future.2 Once thought to be a science fiction fantasy, the ability to replicate models, prototypes, and ideas with a press of a button is now a reality. Three-dimensional (“3D”) printing has the potential to revolutionize the modern industry.

  • Knowledge Reuse for Customization: Metamodels in an Open Design Community for 3D Printing1
    SPECIAL ISSUE: IT AND INNOVATION KNOWLEDGE REUSE FOR CUSTOMIZATION: METAMODELS IN AN OPEN DESIGN COMMUNITY FOR 3D PRINTING1 Harris Kyriakou IESE Business School, Av. Pearson 21, 08034 Barcelona, SPAIN {[email protected]) Jeffrey V. Nickerson and Gaurav Sabnis Stevens Institute of Technology, Castle Point on Hudson, Hoboken, NJ 07030 U.S.A. {[email protected]} {[email protected]} Theories of knowledge reuse posit two distinct processes: reuse for replication and reuse for innovation. We identify another distinct process, reuse for customization. Reuse for customization is a process in which designers manipulate the parameters of metamodels to produce models that fulfill their personal needs. We test hypotheses about reuse for customization in Thingiverse, a community of designers that shares files for three-dimensional printing. 3D metamodels are reused more often than the 3D models they generate. The reuse of metamodels is amplified when the metamodels are created by designers with greater community experience. Metamodels make the community’s design knowledge available for reuse for customization—or further extension of the metamodels, a kind of reuse for innovation. Keywords: Knowledge reuse, metamodels, digital innovation, customization, parametric design, online com- munities, open source, software reuse, Thingiverse, 3D printing Introduction1 chased by consumers (Gebler et al. 2014; Gershenfeld 2008; Raasch et al. 2009).

  • Crowdsourced Design Principles for Leveraging the Capabilities Of
    INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN, ICED15 27-30 JULY 2015, POLITECNICO DI MILANO, ITALY CROWDSOURCED DESIGN PRINCIPLES FOR LEVERAGING THE CAPABILITIES OF ADDITIVE MANUFACTURING Perez, K Blake; Anderson, David S; Hölttä-Otto, Katja; Wood, Kristin L Singapore University of Technology & Design, Singapore Abstract The proliferation of additive manufacturing technologies has inspired its use at different scales for both prototyping and production. Moreover, the accessibility of inexpensive machines has enabled design at the end-user level. However, the unique capabilities of these layer-based manufacturing processes are often underutilized or even unexplored. In this work, the authors leverage a crowdsourced repository of additive manufacturing design data to extract useful design principles for additive manufacturing. Herein, 23 design principles are discussed from said extraction. Many of the 23 principles are found throughout the literature. These lend validity to those that are novel and not yet existing in literature. It is found that the 23 principles range in specificity in how they relate to the manufacturing process The levels of specificity from most general to specific include (i) design for manufacturing, (ii) design for digital manufacturing, (iii) design for additive manufacturing, and (iv) design for fused filament fabrication. The principle, when implements can help designers to fully leverage the capabilities of additive manufacturing technologies. Keywords: Design for X (DfX), Collaborative design, Additive Manufacturing

  • 3D Printing Resource Guide
    3D Printing Resource Guide What is 3D Printing? 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created. 3D printing starts with a digital file derived from computer aided design (CAD) software. Once a design is completed, it must then be exported as a standard tessellation language (STL) file, meaning the file is translated into triangulated surfaces and vertices. The STL file then has to be sliced into hundreds, sometimes thousands, of 2-D layers. This is performed using a software program called a Slicer. The Slicer then sends the job directly to the 3D Printer. A 3D printer then reads the 2-D layers as building blocks which it layers one atop the other, thus forming a three dimensional object. Credit: Penandplastic.com, Wikipedia.com, Pinshape.com, 3DPrinting.com Common 3D Printer Types Fused Deposition Modeling (FDM) 3D printers which use FDM Technology construct objects layer by layer from the very bottom up by heating and extruding thermoplastic filament. FDM printers are popular due to their speed and ease of use. FDM prints require little or no post-processing. FDM printers are limited in their ability to produce finely-detailed objects. Stereolithography Apparatus (SLA) 3D printers using SLA technology work by curing liquid resin with UV light. The light, emitted via laser or a projector, solidifies resin and builds objects layer by layer.

It presents a huge potential for ecology and evolution, sciences with a long tradition of inventing and creating objects for research, education and outreach. Its general principle as an additive manufacturing technique is relatively easy to understand: objects are created by adding material layers on top of each other. Although this may seem very straightforward on paper, it is much harder in the real world. Specific knowledge is indeed needed to successfully turn an idea into a real object, because of technical choices and limitations at each step of the implementation. This article aims at helping scientists to jump in the 3D printing revolution, by offering a hands-on guide to current 3D printing technology. We first give a brief overview of uses of 3D printing in ecology and evolution, then review the whole process of object creation, split into three steps: (1) obtaining the digital 3D model of the object of interest, (2) choosing the 3D printing technology and material best adapted to the requirements of its intended use, (3) pre- and post- © 2020 by the author(s).
