It is known that 3D printing makes manufacturing a lot easier and more precise than traditional manufacturing methods such as molding or machining. Some printers can 3D print using metals and alloys, ...

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 ...

In 2014, eight engineers started a secret project behind the walls of GE Aviation’s headquarters. Their challenge? Build an aircraft engine with 3D printing instead of traditional manufacturing. The ...

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.

Lattice structures are networks of interconnected nodes arranged in repeating or gradually varying patterns called cells.

Although there was briefly a company called Rotary Rocket, the term is much better known as a nickname for the Mazda RX-7 — one of the few cars that used a Wankel, or rotary, engine. If you ever ...

After decades of false starts, America’s leading scramjet engine developers say scramjet-powered hypersonic flight is now within reach. That’s partly thanks to the coming of new 3D printing technology ...
