Multi Jet Fusion (MJF)
Nylon PA12 and PA11 (MJF) 3D printing
Multi Jet Fusion (MJF) fuses nylon powder into dense, detailed parts suited to series production. We offer PA12, white PA12, glass-bead-filled PA12 and PA11, quoted job by job.
What it is for
Nylon in MJF is used for functional series parts: enclosures, ducts, brackets, clips, integrated hinges, gripping tools, spare parts and machine components. The process needs no supports and gives dense parts, with sharp detail and properties that are close in every direction. It suits small and medium runs of identical parts, with no mold.
The surface is slightly rough: do not choose it for transparent or mirror-smooth parts. For a large or very stiff one-off part a carbon-fiber filament nylon is the better fit; for temperatures beyond those of nylon, PPS or PEEK; for chemical resistance and low weight, polypropylene in MJF.

Typical values from the makers' data sheets, measured on specimens under the conditions stated. They are not guaranteed design values: for a critical application ask us for a test on your part.
Design limits
- Build volume
- 380 × 284 × 380 mm
- Minimum wall
- 1 mm
- Dimensional tolerance
- ±0.3 mm up to 100 mm, ±0.3% above
- PA12 White: ±0.5 mm up to 100 mm.
- PA12 Glass Beads (40%): ±0.4 mm up to 100 mm.
- PA11: ±0.5 mm up to 100 mm.
These are the limits of the process, the same for every variant unless stated. For critical dimensions, talk to us before printing.
Which variant to choose
- PA12: the reference grade. Powder maker's data sheet: tensile strength 48 MPa in XY and in Z, elongation at break 20% in XY and 15% in Z (ASTM D638); heat deflection temperature 175 °C at 0.45 MPa and 95 °C at 1.8 MPa (ASTM D648).
- PA12 White: for the same uses, when a white part is needed: tensile strength 49 MPa in XY and 45 MPa in Z, elongation at break 17% in XY and 9% in Z (ASTM D638).
- PA12 Glass Beads (40%): stiffer and more dimensionally stable, less ductile: tensile strength 31 MPa in XY and 30 MPa in Z, elongation at break 9% in XY and 5% in Z (ASTM D638); heat deflection temperature 170 °C at 0.45 MPa. For enclosures, jigs and flat parts that must not warp.
- PA11: the most ductile: tensile strength 52 MPa, elongation at break 35% in XY and 20% in Z (ASTM D638). For clips, hinges and parts that flex or take impacts.
