Material Info

The material HP MJF - PA12, which was specially developed for the HP MJF process, is characterized by a very balanced property profile. It is ideal for functional parts and prototypes due to its high stability and impact resistance. The powder bed-based HP MJF technology allows parts to be printed without support structures. In addition, up to 80% of the excess PA12 powder can be reused.

Look and feel:
Untreated parts have a matte surface that is roughened to the touch. By post-treatment processes, a smooth, homogeneous surface with a slight gloss can be produced.


Dyed SLS parts


MJF parts can be dyed after printing. Textile dye is used for this and you can choose from 17 dark color shades.

Vibratory grinding (tumbling)

Vibratory grinding produces homogeneous and smooth surfaces. For this purpose, an even abrasion is generated on the parts in a vibration trough using grinding stones.

Chemical smoothing

During chemical smoothing, the parts are treated with a solvent vapor. In this way, surfaces are achieved that come close to the quality of injection molded components.

The HP MJF Technology

HP's Multi Jet Fusion technology is currently the fastest and most economical in additive manufacturing. The process is powder bed based and enables the production of extremely high quality prototypes, functional and series parts.

Further materials for the MJF process


This PA12 filled with 40% glass beads is used especially for components that require high rigidity and dimensional stability, such as housings.


The polyamide 11 from HP is tougher than PA12 and tears when force is applied instead of splintering. This is a crucial safety factor, especially in the automotive industry.
