GE engineers builds 3D printed mini jet engine that can reach 33,000 RPM
3D printing have opened so many possibilities for engineers and designers all around the globe to keep on trying something new and fun. Once in a while, there comes an innovative creation that displays the brilliance of 3D printing technique. The latest masterpiece showcasing the technology is a 3D printed mini jet engine which has been created by GE engineers. The fully-functional engine is not just for exhibition as it was power tested at 33,000 rotations per minute. About a foot long and eight inches tall, the small jet engine is built using additive manufacturing, a next-generation technique that make complicated 3D objects by melting metal powder layer upon layer.
Built by a team of technicians and engineers working at GE Aviation’s Additive Development Center outside Cincinnati, the 3D printed mini jet engine was took several years to complete. It would have been very complex for the GE team to build a working model of an aircraft engine, thus they created a simpler engine based on the design of remote control model planes. According to one of the engineers, this was a fun side project to see if they could build a little engine that runs almost entirely out of additive manufacturing parts.
The 3D-printed mini jet engine that can run at 33,000 RPM is currently on display at GE Aviation’s Additive Development Center along with other creations.
