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?

LPBF Alimentazione della polvere

1. Powder supply
Powder supply using cartridges

Deposizione dello strato di polvere

2. Coating
Deposizione dello strato di polvere

Fusione strato di polvere

3. Fusing
Fusing process of the powder by the laser

Cambio di piano

4. Decreasing
Decreasing the building platform & repeat steps 1-4 until the component height reached

Processo di disimballaggio

5. Unpacking process
Take the construction module and remove the powder from interspaces and support structures

Processo di disimballaggio

6. Unpacking process
Separation of the component and the building platform
Separation by band saw or spark erosion

Post elaborazione componente

7. Post-processing of the component
Support removal (Optional)
