Rocket engineering is shifting from painstaking machining and welding to a world where engines and tanks emerge from printers ...

A soldier from the Idaho Army National Guard fires a Javelin anti-tank missile. Colorado-based propulsion firm Ursa Major hopes its new method of 3D printing solid rocket motor cases could one day ...

If you spot a snazzy silver ebike at CES this week, you should know that it's more than just a pretty face. It's the 3D-printed Titanium Zero, and it sports what is claimed to be the world's smallest, ...

(Nanowerk News) An electrospray engine applies an electric field to a conductive liquid, generating a high-speed jet of tiny droplets that can propel a spacecraft. These miniature engines are ideal ...

The 3D printed microturbine engine developed by Technion - Israel Institute of Technology and PTC software seen here in a cut-away showing the internal structure. One aspect of how industrial 3D ...

3D printing is a powerful tool for creating all kinds of stuff, but it has its limits. Hobbyist-focused machines that dispense melted plastic through a nozzle can only make parts that are so strong.

Firehawk Aerospace test-fires a GMLRS-equivalent hybrid rocket engine from a purpose-built, mobile platform. (Firehawk Aerospace) Firehawk Aerospace recently conducted its first flight test of a ...

3D printed materials have come a long way in the last decade or so as printers have become more and more mainstream. Printers can use all kinds of different plastics with varying physical ...

Back in March, a small aircraft in the UK lost engine power while coming in for a landing and crashed. The aircraft was a ...

WASHINGTON — Propulsion firm Ursa Major announced a 3D printing-based approach to designing and manufacturing solid rocket motors it hopes will lead to faster and cheaper production. The strategy, ...

Researchers demonstrated the first fully 3D-printed, droplet-emitting electrospray engine. The low-cost device can be fabricated more quickly than traditional thrusters, potentially from on board a ...
