Phenix PM100
  |
The machine is designed for Selective Laser Sintering – Melting of commercial powders, of metallic or ceramic type. The powder layer formation is performed inside gaz protected chamber, that can be heated up to 900°C. The laser beam comes from Ytterbium doped fiber, is expanded through beam expander, deflected by 2 orthogonal scanner mirrors and focused on f-theta lens . The laser spot on the fabrication plate is estimated to be in the range 60-80 µm, depending on the tuning of the beam expander. Many parts with complicated shapes and fine details have been achieved using the Phenix PM100 machine at ENISE, from both metallic and ceramic powders. Moreover, multi-material construction has been demonstrated for the first time to our knowledge. Once the SLM process is finished, the rough surfaces of the parts have typical rugosity factor Ra closed to 10 µm for powders with granulometry 16 µm at 95%. However, this rugosity can be reduced later using electro-polishing or sandblasting. |
Principle of selective laser melting
 |
Construction of 3D object can be performed from CAD model with Phenix systems CAM-CAD. Powder layer formation and selective laser melting are repeated on successive layers |
