GE engineers make engine using additive manufacturing process

GE engineers have been getting firsthand insights about additive manufacturing as applied to jet engines. News of their success in 3D-printing a mini-jet engine has gathered some attention. The team made a simple 3D-printed engine that roared at 33,000 rotations per minute, said a report. The team who built it are at GE Aviation’s Additive Development Center outside Cincinnati. The focus there is on techniques in additive manufacturing for making 3D structures by melting metal powder layer upon layer.
