HP MJF 3D Printing Capacities

HP Multi Jet Fusion is a powerful 3D printing technology that produces highly accurate and durable parts at fast speeds, especially compared to other powder bed fusion technologies. Multi Jet Fusion parts are great for end-use, low-to-mid volume production, rapid prototyping, or as a bridge process to injection moulding. MJF printed parts can be post-processed by dyeing, sanding and plating.

Lead time: 3 days
Build volume: up to 380 x 284 x 380 mm, while we normally recommend the maximum size of 356 x 280 x 356 mm
Layer thickness: ~0.08 mm
Minimum feature size: 0.5 mm
Minimum wall thickness: 0.6 mm (supported), 0.7 mm (unsupported)*
Tolerance: ±0.3% (± 0.2 mm)

*Please note that parts with a wall thickness above 7 mm will be hollowed

HP MJF 3D Printing Materials

Rigid Plastics

Nylon 11 / PA 11
Nylon 12 (PA 12) glass-filled
Nylon 12 / PA 12 (SLS, MJF)
Nylon 12 full-colour / CB PA 12
Polypropylene (PP)

Flexible Plastics

TPU (Polyurethane)

Finishing Options

As-printed

Parts are de-powdered with a sandblasting process and manual powder removal. The standard finish is matte with a sugar cube-like texture.
Final result:
- Sugar cube-like grainy surface
- Matte appearance
Vapour smoothing

Bathing printed parts in vaporised chemical solvents to create a controlled chemical melt of the material.
Notes:
Can soften sharp edges

Not suitable for small features and thin walls
Final result:
- Smooth in the touch
- Glossy appearance
SLS PA 12, green dyed

SLS PA 12, red dyed

SLS PA 12, yellow dyed

SLS PA 12, black dyed

Dyeing

Colouring parts using dye.

Notes:

The dye penetrates 0.25 mm into the part surface.
Available colors:
- Black
- Blue
- Green
- Red
- Yellow
Spray painting

Provides a continuous, protective color finish which is applied by spraying.
Notes:
Paint coating is just on the surface level, if it is scratched or subjected to wear and tear, the internal natural colour is visible

Possibility of requesting custom colours (RAL)
Available colors:
- Black
- Blue
- Green
- Red
- Yellow
- Custom colour (RAL)
Vapour smoothing + dyeing

Parts are first bathed in vaporised chemical solvents, creating a controlled chemical melt that softens sharp edges and results in a smooth, glossy appearance. Following this, the parts are dyed with the chosen colour.
Notes:
Smooth surface

Glossy coloured appearance
Available colors:
- Black
- Blue
- Green
- Red
- Yellow
Vapour smoothing + spray painting

Parts are first bathed in vaporised chemical solvents, creating a controlled chemical melt that softens sharp edges. The parts are then spray painted to apply a continuous, protective colour finish.
Notes:
Smooth surface

Polished look with coloured surface

Over 200 RAL codes available
Available colors:
- Black
- Blue
- Green
- Red
- Yellow
- Custom colour (RAL)
Custom

If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually 1-2 business days.

Notes:

Submitting for manual review with a custom request does not guarantee a quote.

Pros & Cons of MJF 3D Printing

Advantages	Considerations
Free form design: doesn’t need support features	Limited material and colour choice
Versatile, durable, flexible and chemical resistant material (Nylon)	Surface roughness (however, could be reduced by media tumbling)
Scalable into series	Warping issues for large feature
Fast: Xometry can deliver them in just 3 days
Cheap, especially for small series
