Air Force to Test 3D-Printed Rocket Motors The maker, startup X-Bow Systems, recently accepted investment from Lockheed Martin.

U.S. contractors are scrambling to rebuild missile stockpiles depleted by the war in Ukraine. A new 3D printing approach could restock them fast.

Ursa Major hopes a 3D printing approach to production could one day help replenish depleted stocks of critical weapons such as Javelins and Stingers.

We can’t promise that all the physics are working as they should in this 3D printed version, but in the video after the break it certainly appears to be moving a considerable amount of air.

With Lynx, Ursa Major seeks to solve America’s SRM shortage with a faster, more affordable process. It leverages 3D printing to manufacture multiple motors that promise to outperform legacy systems.

Ursa Major Technologies, manufacturer of liquid rocket motors for launch vehicles, plans to offer 3D printed solid rocket motors for munitions.

However, rather than adding electronics to do the job, Bowen wants to find a mechanical way to have VTEC kick in at high RPM on his air-powered engine.

A fully 3D-printed, air-powered hexapod robot waddles across land and underwater – no electronics required, just soft TPU and compressed air.

Local Motors says its 3D printed frontal crush structure performed at an equivalent level to the crush structure found in a Mercedes-Benz E-Class sedan.
