The division of General Electric – GE Additive presented a 3D printer for printing parts for airplanes at the trade show in Germany. The device is able to spare parts with a diameter of up to one meter. The next layer is formed by sintering the metal powder with a 1-kilowatt laser.
The possibilities of the printer are not limited to this – it can print details and larger: its design allows you to install additional lasers if necessary. According to one of the developers Mohammad Ehteshami, with his help have already printed a jet combustion chamber, and the technology itself can be adapted in the automotive, energy and space industries.
Currently, the printer is beta testing, during which the technology of additives is being developed. Some of them are already used in other units of General Electric. So GE Aviation is engaged in the development of the commercial aircraft engine Advanced Turboprop, where a significant part of the details will be printed on a 3D printer. Thanks to this, the engineers managed to replace 855 “old” parts with 12 new ones.
