Trying to 3D-print a combustion engine in plastic introduces all kinds of problems, though. You have to accept certain limitations of the technology right off the bat.

Some printers can 3D print using metals and alloys, but every technology has limitations. Can a fully functional engine be manufactured using a 3D printer?

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 e… ...

Today you’d 3D print them, but in the 70s, that wasn’t an option. So they used wax. You can see a video about the process, including a build of a model rocket engine, in the video below.

But rather than actually 3D printing an engine, designers 3D print the molds that will define the shape of their engine blocks.

My connection to 3D printing comes from the world of jewelry: the transition from manual to digital prototyping was a real revolution that exploded with the availability of increasingly reliable and ...

That means 3D printing. Increasingly, engineers are favoring a process called selective laser sintering to 3D-print rocket engine parts in an additive process.

Until now, additive manufacturing, commonly known as 3D printing, of engine components was limited by the lack of affordable ...

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 ...
