Overview: How MJF 3D Printing Works?

The Basics of MJF 3D Printing:

Multi Jet Fusion is an industrial 3D printing process that produces functional nylon prototypes and end-use production parts as fast as 24 hours. The printers are unique in that they separate recoating and printing/fusing during the printing stage, making it possible for each process to be separately optimized for performance.

The build unit is moved on to cool after the job is complete, allowing for a continuous printing process. Build times may vary between 8-16 hours, with excellent times ranging from 2-3 times the corresponding build times. This attributes to the longer lead times when compared to PolyJet or Stereolithographic processes. Parts must be allowed extra time to cool to reduce susceptibility to warping and shrinkage.
