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.

The volatile nature of space rocket engines means that many early prototypes end up embedded in dirt banks or decorating the tops of any trees that are unfortunate enough to neighbor testing sites.

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 ...

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 ...

Liquid fuelled engines are throttleable and monstrously powerful, but highly complex. Meanwhile, solid rocket engines are simple and cheap, but once you light them, they’re going full-bore until ...

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 ...

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 ...
