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.
Benefits of MJF 3D Printing
Multi Jet Fusion (MJF) uses fine-grained materials that allow for ultra-thin layers of 80 microns. This leads to parts with high density and low porosity, compared to parts produced with Laser Sintering. It also leads to an exceptionally smooth surface straight out of the printer, and functional parts need minimal post-production finishing. That means short lead times, ideal for functional prototypes and small series of end-parts.

Features of MJF 3D Printing
Advantages
Strength & Durability
Nylon material with strong mechanical and durable properties, perfect for end-use parts.
Scalable Volume
Multiple, identical parts can be built on a single platform at one time, greatly increasing production efficiency.
Geometry
SLS is capable of producing end-use parts on-demand, increasing throughput.
Turnaround
MJF 3D printed parts do not require tooling which reduces the manufacturing lead time from weeks to days, allowing for faster innovation and speed to market.
Efficiency
Designs can be made quickly with a minimum of material waste while maximizing strength and complexity.
Surface & Detail
MJF has tolerances of +/-.012”or +/-.003”per inch, and feature smallest to 0.1mm
Drawbacks
Material Limits
Now MJF has only Black PA12 nylon material, but we can expect metal and fullcolor plastic material coming soon!
Scale Effect
The unit cost and lead time will not be reduced as much as casted or molded parts.
