Profile
The "Additive Manufacturing - Metal" laboratory houses equipment and systems for the additive manufacturing of metallic components using the LBF process (Laser Powder Bed Fusion).
The centerpiece is the MLab Cusing LPBF system from ConceptLaser.
It can be used to manufacture components up to a size of approx. 85 mm x 85 mm x 70 mm (L, W, H).
The system's peripherals include a powder mixer, a sieve system for recycling the metal powder and a nitrogen generator for the continuous supply of shielding gas. A sandblasting system is available for the post-processing of the LPBG-produced components.
The materials available are 316L and CuSn10. Please contact us if you have any manufacturing requirements or similar. To ensure that production runs as smoothly as possible, you should contact us during the design phase so that the special features of additive manufacturing can be incorporated into the design.
