Multi-Jet Fusion(MJF)
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.
Materials we use:
1. Fresh and reused powder are mixed in a processing station and loaded into the printer’s removable build unit.
2. A 3D model is sliced into layers and converted into printer-readable code.
3. The recoater spreads an 80-micron powder layer across the build platform.
4. Inkjet printheads apply two agents: fusing agent where powder should melt and solidify, and detailing agent around edges to control melting and define features.
5. A powerful infrared (IR) lamp melts areas with a fusing agent, fusing the powder together.
6. The build platform lowers step by step as new powder layers are added.
7. Agent application and heating repeat for each layer until the build is complete.
8. Once printing is complete, the build unit is removed and gradually cooled in the unit or a separate chamber.
9. The build is moved to a processing station where loose powder is removed.
10. Recovered powder is filtered, refreshed, and reused.
11. Parts are bead-blasted in a rotary basket to remove surface powder.
