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 SLM system from ConceptLaser.
This can be used to manufacture components up to a size of around 85 mm x 85 mm x 80 mm.
The peripheral equipment for the system includes a powder mixer, a sieve system for recycling metal powder and a nitrogen generator for the continuous supply of shielding gas. A sandblasting system is also available for post-processing the SLM-produced components.
The main starting materials used are Fe and Cu matrixes.
