3D-printed rocket fuel successfully tested, could enable lighter missiles and faster production rates — new additive manufacturing process tested at 1,800 PSI

Chromatic 3D Materials says it successfully static-fired a 3D-printed solid rocket propellant at an Alabama test range.

The propellant withstood combustion pressures above 1,800 psi without structural failure.

The company says its Reactive Extrusion Additive Manufacturing process could speed production and reduce casting defects.

If scaled, the approach could enable custom fuel geometries for higher-performing rockets and missile systems.
