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.

Features of MJF 3D Printing

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

MJF allows to integrate multiple components as well as thin-walled objects and intricate geometries that traditional method won’t be capable of.

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 ±0.012” or ±0.003” per inch, and feature smallest to 0.1mm

Material Limits

Now MJF has only Black PA12 nylon material, but we can expect metal and fulcolor plastic material coming soon!

Scale Effect

The unit cost and lead time will not be reduced as much as casted or molded parts.

MJF Available Materials

MJF Nylon 12 Glass Bead

MJF Nylon 12 Glass Bead is an HP® Multi Jet Fusion nylon material designed for heat resistance, dimensional stability, wear resistance, and high rigidity. It is suitable for assembly and fit checks, functional prototype testing, and low-volume end-use plastic parts, with selection based on the part geometry, load case, and finishing requirements.

Available Finishes

Default:

  • A bead blast removes all powder and leaves a consistent overall texture. Parts are then dyed a standard black color.

Other:

  • Secondary options include a primer that can be applied as well as taps and inserts.

* Want to custom the finish you need? Request in the quoting tool, we'll evaluate your finishes on a case-by-case basis.
