Multi Jet Fusion (MJF)
Powdered thermoplastic is precisely fused by a liquid agent and infrared energy. Parts are cleaned of excess powder and ready for use or a higher level finish.
Multi Jet Fusion offers more possibilities for complex, low-cost parts. Ideal applications are connectors, hinges, brackets, thin-wall ductwork, and housings. It is also great for producing parts in higher volumes.

1
Excess powder removed and lightly bead blasted
Standard finish. Parts have visible layer lines and sandstone texture.
2
Excess powder removed, lightly bead blasted, and sealed to lessen porosity
Sealed finish. Parts have visible layer lines, sandstone texture, and a slight gloss. Parts have a watertight finish.
2 +
Excess powder removed, lightly bead blasted, and cosmetic surfaces sanded to 180 grit
Functional finish, removes some layer lines. Parts have a light texture from sanding.
Excess powder removed, lightly bead blasted, and smoothed using PostPro3D
PostPro3D equipment is used to perform physiochemical smoothing. Smoothed parts have an air-tight, injection molded like finish
3
Sealed, primed, or smoothed with PostPro3D and sanded to 320 grit
Near show quality finish, removes layer lines. Parts may have very fine scratches from sanding. Parts are prime and paint ready.
