Rosswag Engineering, Pfinztal, Germany, a supplier of metal powders, components and qualification services in the metal Additive Manufacturing industry, reports it added a fourth metal AM machine from Alpha Laser, Puchheim, Germany, in December 2020. The new Alpha Laser AL3D-METAL, a Laser Beam Powder Bed Fusion (PBF-LB) machine, is reported to be significantly smaller than the current systems at Rosswag, said to be advantageous for the material qualification process.
The qualification workflow of new AM materials at Rosswag is based on the in-house production of small quantities of metal powder (< 50 kg). The AL3D-METAL machine has the capability to provide initial results about the processing and process capability of metal powders. By derived transfer functions, the identified parameter sets can be scaled to lager PBF-LB machines for prototype manufacturing.
The AL3D-METAL AM machine features an innovative cartridge concept that promises convenient and safe powder handling. Three identical cartridges are required to use the AM machine with one acting as a powder reservoir, the second as a build platform and the third as a powder overflow. The cylindrical build volume has a diameter of 50 mm and a height of 50 mm. The machine’s 200 W laser works with a fine focus diameter of 50 µm for high surface quality.
