LPBF metal printing
How does metal 3D printing work and what does LPBF-process mean?
We have prepared an understandable overview of how metal 3D printing works and how the laser powder bed fusion-process works.
The LPBF process: How does laser powered bed fusion work?
1. Powder supply
Powder supply using cartridges
2. Coating
Deposition of the dust layer
3. Fusing
Fusing process of the powder by the laser
4. Decreasing
Decreasing the building platform & repeat steps 1-4 until the component height reached
5. Unpacking process
Take the construction module and remove the powder from interspaces and support structures
6. Unpacking process
Separation of the component and the building platform
Separation by band saw or spark erosion
7. Post-processing of the component
Support removal (Optional) Beams Surface treatment
