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.
