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, ...

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.

(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 ...

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 ...

3D printing for rocket engines is making a lot of headlines lately. In the last few weeks, we've told you about Aerojet Rocketdyne building and hot-firing a 3D-printed rocket engine and NASA's ...

In a major step toward its upcoming orbital mission, Indian space startup Agnikul Cosmos has successfully conducted a simultaneous test firing of two electric pump-fed semi-cryogenic rocket engines, ...

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 ...

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 ...
