DESCRIPTION:A critical step in production manufacturing is the
  assessment of whether a whether a part has been m
 ade within expected tolerances and free of defects
 . For production additive manufacturing (AM)\, thi
 s step is particularly challenging and costly. AM 
 parts often have complex geometries that can be di
 fficult to measure using conventional tactile prob
 es. Furthermore\, many AM processes have accuracy 
 and the presence of defects that are strongly affe
 cted by part geometry\, motivating new and scalabl
 e measurement strategies. This talk describes rese
 arch on metrology automation to measure and analyz
 e parts made with AM. Our work is conducted in col
 laboration with a commercial AM factory using prod
 uction machines and engineering materials\, allowi
 ng us to study thousands of AM parts and condition
 s relevant for end use applications. The research 
 collects vision information from AM parts includin
 g photographs\, high resolution 2D or 3D scans\, a
 nd X-ray computed tomography (CT). These images ar
 e used to train machine learning algorithms that a
 ccurately recognize defects\, measure part dimensi
 ons\, and predict part tolerances. This scalable m
 easurement automation allows us to collect large n
 umbers of part measurements far beyond what is pos
 sible with conventional methods\, enabling new ins
 ights about the AM production environment. \n\nWil
 liam P. King\, Ph.D. is Professor and Ralph A. And
 ersen Endowed Chair in the Grainger College of Eng
 ineering\, Department of Mechanical Science and En
 gineering. He holds courtesy appointments in Elect
 rical and Computer Engineering and Materials Scien
 ce and Engineering. He is the founder of three com
 panies including Fast Radius Inc.\, which operates
  one of the world’s largest additive manufacturing
  factories and was recognized by the World Economi
 c Forum for its technical achievements. He is a Fe
 llow of ASME\, AAAS\, APS\, IEEE\, SME\, and the N
 ational Academy of Inventors.
