Additive manufacturing expands its application possibilities for USMC.

The USMC explored a new additive manufacturing application with a recent successful testing event at the Yuma Proving Ground in Arizona.

After working with the Corona Division of the Naval Surface Warfare Center, the Program Manager for Ammunition (PM Ammo) at Marine Corps Systems Command (MCSC) assessed a 3D-printed stainless steel head cap for a rocket motor used to detonate an M58 mine clearing Line Charge (MIKLISCH).

The assessment included launching the rocket engine to detonate the demining line charge.

CWO2 Justin Trejo, a project manager at PM Ammo at MCSC, said, “We essentially created a 3D printed product and integrated it into a high-explosive system.”

3D printing enables the creation of a physical object from a digital design. According to the USMC, it’s useful to MICLIC because traditional methods of manufacturing the missile head cap “can be both timely and expensive,” so MCSC wanted to find a more efficient way to manufacture the part.
