NASA’s latest generation of 3D printed rocket engines is not just a materials experiment, it is a direct assault on the cost structure that has defined spaceflight for decades. By combining advanced ...

The Wankel rotary engine was made popular by Mazda, who built rotary style engines from in production cars such as the RX-7, RX-8, and others from 1967 to 2012. The Wankel rotary engine is unique in ...

The private turboprop plane, a Cessna Denali, would use 20% less fuel than comparable models, while providing 10% more power, and 35% of its parts, in fact, more 3D printed components than any other ...

Printing a model jet engine is quite an accomplishment. But it wasn’t enough for [linus3d]. He wanted to redesign it to have a turbojet, an afterburner, and a variable exhaust nozzle. You can see how ...

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 ...

3D printing, though still somewhat of a niche hobby, is growing in popularity. Much of that is thanks to its adoption in various industries. That includes the automotive world, as there are 3D-printed ...

Students from the San Diego chapter of the University of California test-fire a new 3D-printed engine, making UC San Diego the very first university to “additively manufacture” a rocket engine. The ...

MIT researchers built a 3D printer that can produce a fully functioning electric linear motor in about three hours for 50 cents in materials. Linear motors are typically used in optical systems and ...

The moment you finish setting up your first 3D printer, it may feel as though the entire world is at your fingertips. After all, you can craft all sorts of things, from handy tools to beautiful ...
