Just like any other common piston engine, Bowen’s compresses a fuel-air mixture, ignites it, exhausts, and then intakes more fuel. Trying to 3D-print a combustion engine in plastic introduces ...

If 3D printed piston engines aren’t your speed, though, take a look at this jet engine which uses a 3D printed compressor. Thanks to [Rickert] for the tip!

With the 3D-printed fuel structure, the engine can accommodate a wide range of control abilities. This also provides more options for the engines in the future.

3D prints aren’t typically known for their heat resistance. However, [Integza] noted that using the right techniques, it was possible to 3D print parts that could handle steam heat without fa… ...

Gilmous Space successfully developed two types of engines, a hybrid one and a 3D-printed liquid one, for its upcoming rocket launch ...

Western firms such as GE Aviation have incorporated 3D-printed parts, like the fuel nozzles in their best-selling LEAP commercial jet engines, for nearly a decade to improve performance and ...

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 ...

New Zealand-based Rocket Lab has built a rocket engine that's not only 3D-printed -- it uses electric motors to drive the turbopumps.
