Concurrent Technologies Corp. will work with a Desktop Metal subsidiary to demonstrate the practicality of producing obsolete critical castings

BOSTON—Could obsolete critical castings be produced using 3D printed sand-casting mold technology? The Defense Logistics Agency (DLA) has awarded Concurrent Technologies Corporation (CTC) a prime contract worth a potential $15 million to demonstrate the practicality of such production, according to a release from Desktop Metal, Inc.

Concurrent Technologies Corporation will work with subcontractor ExOne, a subsidiary of Desktop Metal, along with DLA, on the project. It will also work with the University of Northern Iowa and metal casting foundries, according to the release.

Desktop Metal said the project will further develop the science and engineering of 3D printed sand-casting molds. The work will demonstrate 3D printed molds and cores for sand castings to the DLA supply chain and to foundries. The foundries could then produce the castings that the industry is not currently positioned to make because traditional tooling is no longer available, Desktop Metal said in the release.

Digital casting is enabled by binder jet 3D printing technology. Replacement parts can be cast in tooling that is printed layer by layer in sand, direct from a digital file, without making physical patterns, the company said.

“Supply chain agility is a core advantage of 3D printing technologies, like binder jetting,” said Ric Fulop, founder and CEO of Desktop Metal, in the release. “And digital casting allows low or high volumes to be produced efficiently and economically. We’re proud to partner with CTC in this project to address casting obsolescence, 3D printed sand molds to ensure defense readiness,”

The base year of the contract is reported to be worth $4.6 million. Four one-year options, if all are exercised, would bring the total value of the effort to a potential $15 million, the company said.
