In [3DprintedLife’s] case, he made a compressed air engine of the Wankel style. The Wankel — a rotary engine — is most famous for its use in some Mazda cars. If you’ve done a lot of 3D ...

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 ...

O n this episode of Engineering Explained, Jason Fenske explains how the wankel rotary engine works.Using a 3D-printed 1/3 scale model of a 13B-REW engine from an FD Mazda RX-7, we get a closer ...

One of them is YouTuber Camden Bowen, who decided to try and make a 3D-printed combustion engine. He’s made engines before, but those were basically just pumps driven by compressed air.

3D printing is revolutionizing rocket development. Whole structures that would usuallu require hundreds of distinct components can be printed in just days.

Of note are Rocket Lab, which uses its 3D-printed engine to launch rockets from New Zealand, and Relativity Space which is 3D printing its entire rocket. In the U.K. there's, Skyrora and Orbex .

Rocket engine start-up Relativity Space shared a video of its 3D-printed rocket engine this week that’s stunning, for what it represents for the future of manufacturing and space travel. The ...

Last year, the company released plans for 3D-printing your own mini jet engine. Unlike the latest engine, the little plastic model cranks by hand and will get nowhere close to 33,000rpm.

The Wankel rotary has a lot of drawbacks as a gasoline engine, ... Fenske uses an incredibly cool 3D-printed cutaway engine to explain exactly why the rotary is so good at burning hydrogen, ...

Last year the press way-overhyped the "3d printed car" which was in reality just a 3d printed auto body over a conventional electric car. With this tech, the car could be truly made with a 3d printer!
