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 ...

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, ...

The 3D printing (digital manufacturing) market has had a lot of hype over the past few years. Most recently, it seems this technology arena has entered the "trough of disillusionment," as 3D printing ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. In Overmatched, we take a close look at the science and technology ...

As a tech demonstration, researchers at GE recently built a miniature, backpack-sized jet engine that they made entirely from 3D-printed parts. And not just for looks, either. They were able to fire ...

Whenever we say that somebudy makes an engine from Lego or paper, it's implied that it doesn't use gasoline to run. But in all other regards, it's a working piece of machinery. Well, it doesn't have ...

NASA's first attempt at using 3D-printed parts for rocket engines has passed its biggest, and hottest, test yet. The largest 3D-printed rocket part built to date, a rocket engine injector, survived a ...

We are all witnessing an unprecedented growth of the aerospace industry and an important part of that is rocket engine development, meant to increase efficiency while cutting costs. One of these ...

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 ...

Remember the guy we featured a few months ago who 3D printed a functional scale model of a Subaru EJ20 flat-four? Well, he's got another creation, and this one's even better. It's a replica of the LS3 ...

Developments in copper-alloy materials and 3D-printing techniques for rocket parts are expected to expedite the process of human occupancy on Mars, as well as improve metal-powder additive ...
