Engineer 3D Prints the 'Forgotten' WWII Steam Rocket Engine

Have you ever heard of the German rocket-powered aircraft Heinkel He-176? If not, you should. This aircraft was noteworthy for a special reason: It was the world's first aircraft to be propelled solely by a liquid-fueled rocket, and the most interesting thing about it was that it was cold! Following his discovery of this aircraft, the YouTuber Integza, who designs and builds all kinds of stuff, decided to do a little research and found out that the engine was a monopropellant engine that used hydrogen peroxide to propel the aircraft forward. And, of course, he had to conduct some extremely interesting experiments, which eventually resulted in the 3D printing of a rocket engine.

While you won't be seeing any flying rockets, the video is still worth a watch. Watching Integza inject materials with a syringe to the build is strangely satisfying, as well as impressive, and makes us think that seeing an actually flying aircraft that uses this system would definitely be an interesting experience. If you're curious to see how he pulled this project off, make sure you give the video embedded above a watch and enjoy!
