Advancements in Monitoring, Beam Shaping, and Cutting-Edge AM Research from The Ohio State University Additive Snack

Imagine printing a car part for the racing industry as your first additive manufacturing (AM) project, earning a process engineer position with Honda Aerospace, and following that up by becoming the AM technology leader at Ohio State University. This is the inspiring story of today’s guest. 
 
Joining host Fabian Alefeld is Ben DiMarco, AM Technology Leader and Principal Engineer at Ohio State University’s Center for Design and Manufacturing Excellence (CDME). In this conversation, they explore Ben’s contributions to lattice structures, process monitoring, and innovative technologies such as nLIGHT and cold metal fusion. They also touch on Ben’s role and passion for workforce development.
