The Additive Manufacturing Users Group (AMUG) has revealed the three winners of AM technical competition.

In the Advanced Concepts category, first place was awarded to Erika Berg, head of application development at Carbon, for a digitally printed helmet liner by Riddell for its SpeedFlex Precision Diamond Helmet. Each liner is custom fit to a player’s head and produced with a lattice structure that uses custom energy-absorbing materials.

The judges announced a tie for first place in the Advanced Finishing Category. Maddie Frank of the University of Wisconsin and Bill Braune of Met-L-Flo Inc were the recipients of first place. Frank’s entry was a 3D-printed electric cello, while Braune made a 30-inch-tall model of a Halo video game character.

The third-place finisher in Advanced Finishing was Andy Allshorn's (At 3D-Squared) replica of the steering wheel medallion for a Century boat while in Advanced Concepts, second place went to Daniel Michalski (Ford Motor Company) and Robert Heath (Eckhart) for their lift assist alternative in manufacturing FWD transmission cases. Third place went to Jack King (DustRam LLC) for 3D-printed DustRam tools that allow dustless tile removal in homes and offices.
