GE Additive has finalized development of a binder jet 3D printing production line which it expects to become live in the second half of 2023.

The process, which incorporates its Series 3 metal 3D printer, can used to additively manufacture (AM) complex, small and large parts with material properties that reportedly exceed casting equivalents with achievable through-hole diameters and wall thicknesses less than 500 μm, the company said.

The technology can make parts up to 25 kg in stainless steel, with no known limitations on maximum wall thickness, according to GE. It is also possible to de-powder intricate parts without destroying fine features, sinter parts within the desired tolerances, and reduce surface roughness.

“Customers shouldn’t have to reconfigure and tweak machines once they have been installed on their shop floor,” said Josh Mook, chief engineer at GE Additive.

The company says that installed production lines could include up to 100 3D printers, which, if automated, could help increase productivity.

 The binder jet line can also be installed and operated without hazard zoning required and has been designed for less operator contact with the system and metal powders.
