How Does Multi Jet Fusion work?
Multi Jet Fusion is a powder-based technology but does not use lasers. The powder bed is heated uniformly at the outset. A fusing agent is jetted where particles need to be selectively molten, and a detailing agent is jetted around the contours to improve part resolution. While lamps pass over the surface of the powder bed, the jetted material captures the heat and helps distribute it evenly.
The 3D model
A fusing agent and a detailing agent are jetted to selectively melt powder particles and improve resolution
Lamps pass over the surface constantly, the jetted material captures and distributes the heat
The process continues building up the part layer by layer
The loose powder is removed
The part is finished
