Please welcome Dr. Timothy Simpson to the ISE Department. Dr. Simpson is the Paul Morrow Professor of Engineering Design and Manufacturing at Penn State University. He will discuss the challenges and research opportunities in advanced manufacturing.
As always refreshments are available in 428 Daniels Hall 30 minutes before the seminar begins.
Additive manufacturing provides engineers with unprecedented design and material freedom. Thanks to additive manufacturing (AM) technology, engineers can consolidate assemblies into a single integrated component, lightweight parts using topology optimization and lattice structures, and functionally-grade structures and components made from multiple materials. While many advocate that “complexity is free” when it comes to AM, understanding the design, material, and process limitations associated with AM is important when producing end-use parts. This talk will discuss the challenges associated with part substitution, consolidation, and optimization for AM, with an emphasis on laser-based powder bed fusion systems. Several examples will be presented to illustrate the challenges associated with design workflow, part selection, and support structures. These examples are drawn from the activities in Penn State’s Center for Innovative Materials Processing through Direct Digital Deposition (CIMP-3D), which serves as the DARPA Open Manufacturing Program’s Additive Manufacturing Demonstration Facility (MDF). CIMP3D’s mission is to (1) advance enabling technologies required to successfully implement AM technology for critical components and structures; (2) provide technical assistance to industry through selection, demonstration, and validation of AM technology as an “honest broker”; and (3) promote the potential of AM technology through training, education, and dissemination of information. CIMP-3D also provides Penn State’s interface to America Makes, the National Additive Manufacturing Innovation Institute (NAMII). Efforts to educate the next generation workforce and (re)training the current workforce to use AM effectively will also be discussed.
Dr. Simpson is the Paul Morrow Professor of Engineering Design and Manufacturing at Penn State with affiliations in Information Sciences & Technology and Architecture. He also serves the co-Director of CIMP-3D (www.cimp-3d.org) and helps manage an additive manufacturing research portfolio that exceeds $8M/year. He has been PI or Co-PI on over $25M in funding for his own research in product family and product platform design, additive manufacturing and 3D printing, and design innovation and entrepreneurship. He has published over 300 peer-reviewed papers and 2 edited textbooks, and he is currently co-authoring a new textbook on Design for Additive Manufacturing. He teaches courses on Mechanical Design, Additive Manufacturing & Reverse Engineering, Industrial Systems Design, Concurrent Engineering, and Product Family Design. He is a recipient of the ASME Ben C. Sparks Award, the ASEE Fred Merryfield Design Award, the SAE Ralph R. Teetor Award, and a NSF Career Award. He has received awards for outstanding research and teaching at Penn State, including the 2007 Penn State President’s Award for Excellence in Academic Integration. He is a Fellow in ASME and an Associate Fellow in AIAA. He currently serves on the ASME Design, Manufacturing, and Materials Segment Leadership Team and is Chair of the ASME Design Engineering Division (DED) Executive Committee. He helped ASME launch the Innovative Additive Manufacturing 3D (IAM3D) Design Challenge in 2014, and he helped launch and served as Chair of the Executive Advisory Committee for the 2015 and 2016 ASME Additive Manufacturing and 3D Printing Conference & Expo. He received his Ph.D. and M.S. degrees in Mechanical Engineering from Georgia Tech and his B.S. in Mechanical Engineering from Cornell.
