Event Scheduled for Feb 22, 2013
Event: ME 2013 Spring Seminar Series: 'Additive Manufacturing – A Manufacturing Revolution for the 21st Century,' David Bourell, The University of Texas at Austin
Location: UTEB 150
Time: 02:00 pm
Details of Event:
Additive Manufacturing (AM) is a collection of manufacturing processes which build parts typically from a liquid or powder in a layerwise fashion. Effectively, AM fabricators are 3D printers, enabling actually parts to be “printed” from a computer image akin to ubiquitous 2D printers. This results in the capability to economically and quickly produce small production runs of parts with highly complex geometries. This presentation has three parts. First is an introduction to AM technologies including the state of the art commercially, the historical development of the field and a review of the primary application areas industrially and societally. The second part of the presentation deals with two research topics from the presenter’s lab: electrolytic deposition of porous, nonmetallic laser sintered preforms and mechanical property development in laser sintered polyamide (nylon). Both topics have long-range objectives of developing new materials and processes for AM as well as accelerating the transition of AM polymeric parts into service applications. Finally, a perspective will be given on fruitful areas of AM research and the future of AM.
Dr. David L. Bourell is the Temple Foundation Professor of Mechanical Engineering at The University of Texas at Austin. He is currently Director of the Laboratory for Freeform Fabrication. Dr. Bourell's areas of research include particulate processing with emphasis on sintering kinetics and densification, and materials issues associated with Laser Sintering (LS). He holds 9 primary patents dealing with materials innovations in LS dating back to 1990 and has published over 200 papers in journals, conference proceedings and book chapters. Dr. Bourell is a Fellow of ASM International and TMS, and he is also a lifetime member of TMS. In 2009, he received the TMS Materials Processing and Manufacturing Division Distinguished Scientist/Engineer Award. He has received two major conference career awards in additive manufacturing: the SFF Symposium FAME Award and the Portuguese VRAP Career Educator Award. Professor Bourell is a leading expert in advanced materials for Laser Sintering, having worked in this area since 1988. Dave was the lead author on the original materials patent for LS technology. Issuing in 1990, this patent has been cited by 150 other patents, and it represents the original intellectual property for mixed and coated powders for LS, including binders.
