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.

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 ...

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 ...

NASA's Reactive Additive Manufacturing for the Fourth Industrial Revolution (RAMFIRE) project test-fired a 3D-printed engine nozzle at Marshall Space Flight Center in Alabama. See the test in ...

MIT engineers have demonstrated the first fully 3D-printed, droplet-emitting electrospray engine. The device, which would be ideal for enabling small satellites to make in-orbit maneuvers, can be ...

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 ...
