MJF — Multi Jet Fusion
MJF (Multi Jet Fusion) jets a fusing agent across a bed of nylon powder and fuses it with infrared energy, producing dense, consistent, production-grade parts faster than SLS — with finer detail and excellent repeatability.

How MJF works
An inkjet array sweeps across each layer of nylon powder, depositing a fusing agent exactly where the part should be solid and a detailing agent around the edges for sharpness. Infrared lamps then pass over the bed, fusing the treated powder in a single sweep. The whole layer is processed at once, which makes MJF fast and highly repeatable.
The result is dense, strong parts with fine feature detail and a smooth matte finish. MJF is particularly well-suited to production batches because part properties are consistent from one unit to the next.
What MJF is best for
- Production-grade nylon batches
- Complex functional assemblies
- Ducts, housings, and manifolds
- Parts needing fine detail and strength
- Bridge production before injection moulding
Strengths & trade-offs
Strengths
- Dense, strong, repeatable parts
- Finer detail than SLS
- Fast batch throughput
- Fine matte surface
Trade-offs
- Native colour is dark grey
- Slight surface porosity
- Colour requires dyeing
- Best value at volume
