Tuesday, January 14, 2014
9:00 AM - 3:00 PM, check-in begins 8:30 AM
Jackson Hall, room 2-137 (2nd floor, bldg west side)
University of MN, Twin Cities East Bank Campus

Directions and Parking: Road construction is underway at the University. When planning your visit, please review campus building and parking locations and allow for extra travel time. (PDF map)

This IPrime Mid-Year Workshop is presented by the Coating Process Fundamentals (CPF) program and Minnesota Nano Center (MNC). Coordinator: Satish Kumar, CPF program co-leader. Registration is required.

The goal of this workshop is to identify fundamental research needs in the emerging areas of 3D printing and additive manufacturing. These needs may be related to the materials that are used, the processing of those materials, and the resulting products. Both industrial and academic perspectives will be presented.

To Attend 
Register here by Friday, Jan 10. This workshop is free and open to IPrime member companies, invited guests, and University of Minnesota faculty, students, and staff. Prospective IPrime members interested in attending an IPrime event as a guest should contact Bob Lewis, ph: 612-625-1269.

Workshop Schedule
8:30 AM Check-in begins (light breakfast served)

9:00 AM Welcome

9:15 AM Frontiers in Additive Manufacturing (aka 3D Printing):               Expanding Multi-Disciplinary Horizons
Ryan Wicker, Univ. of TX, El Paso
Abstract: Many media outlets as well as President Obama have been featuring additive manufacturing (AM) technology with a common theme that AM, perhaps more well-known as 3D printing, represents a technology driving the Next Industrial Revolution. Is this attention warranted, and if so, how will AM drive this revolution? This presentation will address the current state-of-the-art in AM and how these technologies can be used in a wide range of multi-disciplinary and collaborative research, teaching, outreach, and entrepreneurship activities. Existing AM technologies can be effectively used in a host of applications ranging from printing organs to satellites. However, significant progress is required to develop the methods and systems for fabricating objects with full spatial control over material placement and structure creation that once achieved will lead to direct printing of, for example, a cell phone. There are myriad issues associated with combining multiple materials to create functional products - from the deposition and processing of different materials to the combined performance of the materials in the resulting product. Despite these issues, the opportunities for AM in aerospace, defense, biomedical, energy and enumerable other applications continue to expand as the achievable length scales in AM decrease, the number of materials available for use in AM increases, the performance of these materials are characterized and controlled in the final product, and new strategies for integrating AM with other manufacturing technologies are successfully demonstrated.

11:10 AM Water-Based Coatings for 3D Printed Parts
Jenny Zhu, Stratasys
Abstract: 3D printing has become one of the hottest technologies in creating new ideas and exploring new possibilities. It turns a digital model into a three-dimensional solid object, allowing people to hold it, touch it, and feel it. Since 3D printed parts are built through layer-by-layer depositions, they exhibit limiting surface qualities which can be improved by post-treatments. Coatings are one of the many post-treatment techniques which have not been well-explored for 3D printed parts. I will share some fundamental works on applications and characterizations of water-based coatings for 3D printed parts. I'll also present some results of improved surface properties obtained from water-based coatings such as improved surface smoothness, metallic surface finish, sealed voids for preventing water leakage, hydrophilic and/or antimicrobial surface for medical devices, etc.

11:50 AM Current Needs and Applications of 3-D Printing in the                Medical Device Industry
Bruce Forsyth, Boston Scientific
Abstract: 3D printing is a type of additive process technology where a physical object can be constructed by growing successive layers of polymer or metal material to reach a final manufactured design. In the medical device industry, this printing capability can be useful to create precision tooling, artificial biological reconstructions or rapid prototypes for integration into more complex systems. A brief description of the technology and its current uses will be highlighted.

12:15 PM Lunch & Discussion (Box lunch provided for industry & faculty)

1:30 PM Bionic Nanomaterials
Mike McAlpine, Princeton University
Abstract: The development of a method for interfacing high performance devices with biology could yield breakthroughs in regenerative medicine, smart prosthetics, and human-machine interfaces. Yet, most high quality inorganic materials are two dimensional, hard and brittle, and their crystallization generally requires high temperatures for maximally efficient performance. These properties render the corresponding devices incompatible with biology. Nanotechnology provides a route for overcoming these dichotomies, by altering the mechanics of materials while revealing new effects due to size scaling. Our group has focused on several vital areas for biointerfacing nanodevices: 1) graphene nanosensors for ubiquitous detection, and 2) piezoelectric nanoribbons for interfaced biomechanics. Our approach involves the following key steps: first, new nanomaterial generation; second, fundamental studies of novel properties; and finally, interfacing these nanomaterials with biology. We have also developed a future vision of bionic systems in which the electronics and biology are seamlessly interwoven in 3D. The novel properties of nanomaterials coupled with "living" platforms may enable exciting avenues in fundamental studies and bioMEMS applications, including creating augmented bionic nanosystems.

2:30 PM Aerosol Jet Printing of 3D Electronic Circuits
Mike Renn, Optomec
Abstract: In this paper, we present a novel non-contact printing approach called Aerosol Jet™. This tool creates a collimated jet of aerosol droplets that extend 3-5mm from the nozzle to the target. The printed features can be as small as 10um and a wide assortment of materials can be printed such as metal nano-particles, polymers, adhesives, ceramics, and bio-active materials. The nozzle direction and 3D positioning is controlled by CAD/CAM hardware which allows conformal printing over 3-D surfaces. Example applications such as printing 3D antenna for mobile devices will be presented.

3:10 PM Automation
John Oney, Stratasys
Abstract: Mass finishing for additive manufacturing and automation of the post process.
