Romanian Engineer 3D prints first ever airplane engine prototype

The aerospace industry has been making gains left and right thanks to additive manufacturing technology. Between investments made by large corporations that are helping to create 3D printed parts for the interior of planes, to the creation of a giant 3D printer in South Africa that will be used to print parts for aircrafts, there is no stopping the expansion of 3D printing across the aerospace industry

Valentin Stamate, a Romanian engineer and leading researcher at the Transilvania University in Brasov, Romania, is helping this expansion with the unveiling of his latest innovation: a 3D printed two-stroke airplane engine prototype. As the one of the first two-stroke engines ever to be created almost entirely from 3D printing; this is a huge achievement for additive manufacturing and the aerospace industry.

Using SLM and SLS printing technology with steel, aluminum, and bronze infused steel powders; Stamate was able to print the entirety of the engine. The only parts that were not 3D printed were the propeller, which was made of wood, the cone with its clamping system, the bearings, the bolts, the nuts, and spark plug. In all, this engine has a total size of 10 cm3 and can make 10,000 revolutions per minute.
