ConferenCe Details This presentation will focus on 3D printing using binder-jetting technology, via volume mathematics as the design platform, to produce innovative designs in metal that heretofore where unattainable. This new generation 3D volume modeling platform, which uses real, or true, volume modeling, unlike traditional industrial approaches that are based on meshes, parametric surfaces or voxels, will be utilized to make metal cellular lattice structures. the processes, as well as the most common materials will be discussed. Samples will be handed out to the audience. 2:30–2:55 pm Legal and Policy Issues Connected to Consumer Use of 3D Printing Michael Weinberg, Vice President, Institute for Emerging Innovation, Public Knowledge 1:30–1:55 pm Using 3D-Color Coding to Communicate Design Intent Vito Gervasi, Director, R&D, RPR, Milwaukee School of Engineering Over the past decade color 3D printing has become part of the fabric of NPD in many companies. Its use for conveying more than geometric information has also been leveraged in producing communication models with attributes such as atomic CPK coloring, FEA analysis results, cellular structure, topographical mapping of planetary surfaces, and the list goes on. Recently, as a result of facing a challenging design communication task on a multi-colored, multi-insert, multi-shot molecule design, the presenter determined color-coding would be the preferred method for conveying design intent for many engineering designs. This presentation will present our survey findings to-date on color-coding activities and present examples of how to use several proposed standards developed at MSOE. Case studies will be examined in more detail and some color-coding challenges and thought-processes will also be presented. 2–2:25 pm How to Design for Additive Manufacturing Technology Direct Metal Laser Sintering (DMLS) Adam Galloway, VP Sales & Marketing, GPI Prototype and Manufacturing Services Inc. As AM moves beyond large commercial/industrial applications and toward consumer markets, it is likely to receive increased scrutiny from policymakers and other, potentially “disrupted,” industries. The AM community will need to become familiar with legal and policy challenges that are well known to the internet and consumer electronics industry, such as copyright, digital rights management, and liability for user actions. Public Knowledge is a nonprofit consumer rights organization based in Washington, DC that has been focusing on these issues for over a decade. The goal of this talk is to begin to share what we are currently doing and to sketch out a roadmap for the future. 3 – 3:25 pm Intellectual Property Issues in Additive Manufacturing William J. Cass, Partner/Attorney, Cantor Colburn LLP Intellectual property is a key component in the development of new products and inventions in additive manufacturing. Determining the intellectual property rights to a new design or method at the start of a project is a critical step. Common forms of intellectual property protection, such as contracts, patents, trademarks and copyrights, will be reviewed. Potential pitfalls and how to avoid them (in the context of additive manufacturing) will also be discussed. The presentation will start with a brief overview of the following additive processes: DMLS, SLA, SLS, FDM, and 3D printing including Objet and ZCorp. The presentation will then move into the accuracy of the processes compared to one another. Finally, it will show different examples of parts and their failures which will also include how to design for the process. The design will include prototype tolerances and then additive manufacturing with a main focus on DMLS (complex geometries, internal passageways and much more). Pros and cons for each of 50 sme.org/rapid

Direct Write Printed Materials & Electronics 10 am–3:25 pm The technology is advancing beyond research and development. Hear about applications of additive manufacturing for printed electronics and other related products. 10–10:25 am Printed Optics: Interactive Objects and Devices using Optically Clear Materials and Embedded Components Eric Brockmeyer, Lab Associate, Disney Research Pittsburgh Karl D.D. Willis, PhD, Principal Research Engineer, Autodesk Additive manufacturing technology allows us to create unique, personalized products for consumers and experiences for guests of Disney parks, hotels, and resorts. We believe that the next generation of these products will enable us to integrate interactive display, sensing, and illumination elements. Our research using jetted additive manufacturing explores novel techniques for creating optical components and a variety of applications. Our library of optical components includes: optical fiber-like ‘light pipes,’ internal light reflectors using enclosed air pockets, micro lens arrays, and embedded opto-electronic components. We used an Objet Connex 260 and have developed techniques for routing light pipes, building overhanging geometry without support, and smoothing/finishing optical components while still in the machine. These techniques are used in a range of applications to guide light from displays onto arbitrarily shaped objects, to reflect light in 3D displays and lighting elements, and to embed opto-electronic components for touch sensing. We believe additive manufacturing of optical components will enable unique, personalized interactive objects for consumer products and experiences of the future. 10:30–10:55 am Complete Electrical Assemblies Made with Additive Manufacturing: Medical Applications Mario Urdaneta, PhD, Staff Scientist/Engineer, Weinberg Medical Physics Additive manufacturing typically uses a single material type, whether it is plastic, metal, or ceramic, to make an entire part. Rapid prototyping parts that combine different materials (e.g., conductors and insulators as in an electrical motor) in a single process are not yet an option. We have developed methods to make rapid prototype parts that combine electrical conductors and insulators for making MRI gradient and RF coils. The parts include wires, insulation, cooling lines, and supporting structures. Our primary motivation is rapid prototyping MRI wires (i.e., Litz-like wires), which must be woven in sophisticated patterns to reduce proximity and skin-effects that produce losses at high frequencies and currents (patent pending). Our additive manufacturing approach will bypass the months-long and nearly-artisanal process of winding a Litz wire. Using additive manufacturing we can make wires with very tight turns, leading to coils that take less space and enable the design of MRIs with non-traditional shapes (e.g., dental MRI). We anticipate that eventually additive manufacturing of conductors and insulating structures will revolutionize the manufacturing of many electromagnetic components, especially in high-frequency applications (e.g., hybrid cars). 11–11:25 am Fabrication and Characterization of 3D Printed Compliant Tactile Sensors Jae-Won Choi, Assistant Professor, University of Akron Morteza Vatani, PhD Candidate, University of Akron Erik Engeberg, Assistant Professor, University of Akron Additive manufacturing technology with a direct-write conductive material is one promising approach to produce compliant tactile sensors. In this work, a multi-layer compliant tactile sensor was developed using a hybrid manufacturing process with an existing projection micro-stereolithography and micro-dispensing process. The sensor was designed to detect changes in resistance as it is deformed. A compliant skin structure was built layer-by-layer using a stretchable photopolymer in the micro-stereolithography system to cover the conductive elements. These sensing elements were created within the skin material by the micro-dispensing of a compliant conductive material during the micro-stereolithography process. The fabricated tactile sensor consists of two layers of sensing elements within the skin structure; there are eight stretchable straight wires in each layer. The wires in the second layer were orthogonally placed atop the first layer so that the sensor can detect various external forces/motions in two dimensions. To introduce conductivity, carbon nanotubes were dispersed in the stretchable photopolymer. The fabricated sensor was 6/2013RAPID 51
