Material introduction: Nylon PA12 MJF

Nylon PA12 (MJF) with its excellent mechanical properties and detailed surface resolution, is exceptionally versatile and the ideal material for a wide range of applications.

The material has a high impact resistance, due to different geometries it can either be flexible or rigid. The printing technology gives you extensive freedom of design.

By using HP Multi Jet Fusion (MJF) technology, your parts have a higher density, lower porosity and are watertight compared to parts produced with Selective Laser Sintering (SLS). Furthermore the part have homogeneous (isotropic) mechanical properties.

Typical use and our use cases

Complex models, prototypes, architectural models, industrial parts, spare parts, housings

Technology

The 3D print process begins by laying down a thin layer (0,08 mm) of nylon powder on a build platform. Next a print head passes the surface while jetting a fusing agent, where the powder should fuse. Also a detailing agent is applied at the boundaries of the parts to produce sharp and smooth edges. In order to fuse the selected areas, fusing lamps pass the surface. The build platform moves down and the next thin layer is being applied.
