Binder Jetting Production Workflow at Freeform Technologies

Freeform Technologies of St. Mary’s, Pennsylvania, is a contract manufacturer relying on various processes employing powder metal and sintering — most notably binder jetting. Thanks in part to a recent acquisition that significantly expanded its capacity, the company now runs 22 binder jetting machines. In a recent article for Additive Manufacturing Media, we reported on Freeform Technologies and its approach to binder jetting for metal part production.

As much as with any other AM process, additive manufacturing via binder jetting involves more than just the 3D printing. After the form of the part is made in the binder jetting operation, the part needs a sequence of downstream steps. Peter Zelinski's visit to Freeform gave him a chance to walk through this sequence, and he describes each step in the binder jetting process in this video. Those steps include curing, depowdering, sintering and inspection. To this list, Freeform routinely adds tumbling, and this video discusses why.
