MJF 3D Printing Service
Multi Jet Fusion is a very common branch of 3D printing. It is useful in a wide variety of applications and projects, from ATV modification parts to office storage accessories. Read more about this service below.
What is Multi Jet Fusion?
The process of MJF printing is done by layering a polymer or nylon material powder into a powder bed of a 3D printing machine. Then, a binding agent is deposited as directed by the design file. Lastly, a laser runs over the powder bed, solidifying the design. This process is repeated until the part is complete.

Surface finishes for MJF 3D printing
We offer 3 types of surface finishes for MJF Printing
Raw
Part is taken from machine and excess powder is removed
Polished
Part is tumbled and then shot-peened providing a smooth surface
Vapor Polished
Parts are smoothed in a machine, providing an injection-molded surface look

Advantages and drawbacks of MJF 3D printing
Advantages
- Structurally strong parts
- Quick results
- Highly precise dimensions
- Minimal material waste
Drawbacks
- Default part color is dark grey
- Parts can only be dyed to darker colors
- Limited material options
Designing files for MJF printing
We can print your parts off almost any 3D CAD file, including .STL, .3MF, and .OBJ. The minimum dimension we suggest for your parts in 1 mm to help protect the quality of the print. We also offer in-house CAD file design assistance. For more information, email [email protected].
