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.

In the fall of 2023, NASA hot fire tested an aluminum 3D printed rocket engine nozzle. Aluminum is not typically used for 3D printing because the process causes it to crack, and its low melting point ...

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 ...

Aerospike rocket engines are the stuff of legend in the space industry. Conceived in the 1960s, their unique spiked-nozzle design promises better efficiency, reusability, and performance at all ...

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 ...

Many firsts: The Agnikul mission was packed with multiple firsts that have significant implications both for India and the world. It marked the country's inaugural rocket launch from a privately owned ...

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 ...

One of these nine Rutherford engines used during the May 2022 There And Back Again mission could return to space later this year. Photo: Rocket Lab Reusability is the key to 21st century spaceflight, ...

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 ...
