Selective LaserSintering(SLS)
MJF (Multi Jet Fusion) and SLS (Selective Laser Sintering) are both powder-based 3D printing technologies that build parts layer by layer using fine polymer powders. Although they differ significantly in how they fuse the powder – both methods offer high precision, good mechanical properties, and are well-suited for functional prototypes and end-use parts.
1. Powder is loaded into the printer’s feed system.
2. N₂ is introduced into the build chamber for materials that require it.
3. A 110-micron layer is spread over the build platform by the recoater.
4. A CO₂ laser selectively sinters the powder, forming solid cross-sections.
5. The build plate lowers incrementally.
6. Spreading, sintering, and lowering repeat until printing is complete.
7. Once printing is complete, the build chamber and parts cool gradually inside the unit.
8. The build is moved to a post-processing station to remove loose powder.
9. Recovered powder is filtered, refreshed, and reused.
10. Parts are bead-blasted in a rotary basket to remove surface powder.
