Thermal energy selectively fuses regions of a powder bed
A process in which thermal energy selectively fuses regions of a powder bed.
It can be made by two different sources, Laser or Electron Beam.
- A layer, typically 0.1mm thick of material is spread over the build platform.
- A laser fuses the first layer or first cross section of the model.
- A new layer of powder is spread across the previous layer using a roller.
- Further layers or cross sections are fused and added.
- The process repeats until the entire model is created. Loose, unfused powder remains in position but is removed during post processing.
