Using 3DFoundri's proprietary MAF polishing technology, <2 min polished from 200 nm to 30nm Ra (mirror-like)



3DFoundri, Inc. is an East Lansing, Michigan, start-up dedicated to developing advanced metal manufacturing technologies that will enable cost reductions and increase part complexities. The initial product is a Magnetic-Field Assist Finishing (MAF) slurry that, when combined with a CNC Platform, allows mold manufacturers to reduce their manufacturing costs by at least 20% per mold by eliminating labor in polishing for Class A cosmetic parts.  It will also reduce mold manufacturing time by 30%, reducing the lead time for their customers. 

The company was founded in February 2020 by Ken Foster, Ph.D., and Professor Patrick Kwon and Professor Haseung Chung of Michigan State University’s Mechanical Engineering Department. 


Ken Foster, Co-Founder and CEO – Ken has a Ph.D. in Materials Science and Engineering and more than 30 years of product development experience commercializing complex disruptive technologies into numerous markets, including automotive, electronics, industrial, and aerospace.  He has expertise in all aspects of the specialty chemical industry, including leadership, R&D, manufacturing, sourcing, intellectual property and innovative technology development at Dow Chemical, GE Plastics joint ventures, Momentive Performance Materials (MPM former GE silicones business). 


Dr. Patrick Kwon, Co-Founder – Dr. Kwon is a professor in the Department of Mechanical Engineering at Michigan State University (1996-Present). He has carried out the leading-edge research to advance the current knowledge of machining and powder metallurgy. In his 24-year academic career, he has published nearly 200 publications and received 4 granted and pending patents in the areas of machining, powder metallurgy and additive manufacturing.


Dr. Haseung Chung, Co-Founder - Dr. Chung is an Assistant Professor at Michigan State University's Department of Mechanical Engineering (2017-present). He received his Ph.D. from the University of Michigan with his dissertation on processing and properties of functionally graded polymer composites produced by selective laser sintering. Dr. Chung has extensive experience in advanced manufacturing, including additive manufacturing (AM), surface finishing process, fabricating multi-material structures, including functionally graded materials. He also has expertise in statistical quality design and control in manufacturing process.
