Dr. David Bourell: Additive Manufacturing

Dr. David Bourell is Professor of Mechanical Engineering (ME) and Materials Science and Engineering (MS&E) at The University of Texas at Austin. He is currently the Temple Foundation Professor and Director of the Laboratory for Freeform Fabrication. He is internationally recognized in the field of Additive Manufacturing (AM).

Additive Manufacturing, also known as 3D Printing, is a group of technologies used to create 3D objects from computational data. Just like 2D printing on a page, these technologies create the solid objects without part-specific tooling. The dozen or so commercial processes rely on creating the object in a layerwise fashion by sending slices of the computational digital image to a fabricator.

Dr. Bourell has been involved in the materials aspects of AM for 25 years. Current projects focus on transitioning the technology from prototype parts to actual service applications. This requires production of parts with acceptable mechanical properties as well as surface finish and tolerance. He is working with metallic infiltration into porous preforms, mechanical property enhancement in laser sintered polyamide 12 and production of silicon carbide and graphite laser sintered parts using transient binders.
