A liquid-fuel rocket engine is just about the hardest thing anyone could ever build. There are considerations for thermodynamics, machining, electronics, material science, and software just to have ...

3D printing has emerged as a powerful technology, revolutionizing industries such as manufacturing, design, architecture, and even healthcare. With the growing demand for 3D print files, finding ...

Relativity Space, a well-funded startup, is going all-in on additive manufacturing. But is that too much of a good thing? The once pristine white floors featured in Relativity Space’s PR photos are ...

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 ...

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 neighbour testing sites.

Relativity plans to 3D print almost every single component of its 200-foot-tall orbital rockets, called Terran 1. And Ellis says this is why investors are so intrigued, drawn in by the promises that ...
