MJF 3D Printing uses strong, versatile materials
Leading companies in many industries turn to MJF for its industrial-grade materials.
| Material | Color | Resolution | Tensile strength | Elongation at break | Heat deflection temperature | Application |
|---|---|---|---|---|---|---|
| HP PA 12 (Nylon 12) | Gray, dyed black | 80μm | 48 MPa | 15-20 % | 95-175 °C | Functional prototypes, complex assemblies, watertight applications |
| Glass-filled HP PA 12 (US only) | Gray | 80μm | 30 MPa | 6.5 % | 121-173 °C | Enclosures, housings, cases, fixtures, structural parts, tooling |
Surface finishes for MJF 3D printing
One of the benefits of MJF 3D printing is the quality of the part surfaces, especially after finishing. Here are the surface finishes available for MJF.
As printed (grey)
Grey colour, smooth surface, no visible layers, powder texture
Dyed (black)
Dyed black by immersion in a warm dye bath. The colour penetrates to a depth of approximately 0.5mm on all surfaces.
Tumble polishing
Parts are placed in a tumbler of ceramic chips to give a polished finish similar to injection moulding.

The Basics of Multi Jet Fusion
Multi Jet Fusion is a 3D printing technology introduced to the market by HP in 2016. The company explains its technology is built on decades of HP’s investment in inkjet printing, jettable materials, precision low-cost mechanics, material science, and imaging.
In a nutshell, the technology involves using a type of liquid binding agent to fuse together powdered polymer material layer by layer. The technology gets its name from the multiple inkjet heads that carry out the process of distributing the liquid polymer (or binding agent).
