GE building the world’s largest laser-powered 3D printer

GE Additive[1], a new GE 3D printing business, is developing the world’s largest laser-powered 3D printer. The 3D printer will produce parts from metal powder which can fit inside a cube with 1-metre sides. “The machine will 3D print aviation parts suitable for making jet engine structural components and parts for single-aisle aircraft,” said Mohammad Ehteshami, VP of GE Additive.

“It will also be applicable for manufacturers in the automotive, power, and oil and gas industries.” The 3D printer fuses fine layers of powdered metal with a laser beam and prints three-dimensional objects from a computer file. With few limits on the final shape, the method gives engineers new freedoms and eliminates the need for factories filled with specialised machines.
