Material Info

About

Multi Jet Fusion (MJF) Plastic PA12 is HP’s nylon plastic with excellent mechanical properties and a slightly grainy finish. In black, it is also available in a smooth and slightly glossy finish. MJF Plastic PA12 is an ideal choice for a wide range of applications from industrial parts to durable end-use goods. Its strength, durability and stiffness make it great for functional parts, such RC car parts and mounts. It is also popular for home decor, eyewear and games. MJF Plastic PA12 is printed using HP’s Multi Jet Fusion technology and supports very complex geometries and thin features. More information about this printing technology can be found Here

Color & Finishes

Gray

A shade of gray that can vary in lightness

Black

Natural
This finish has a matte finish and slightly grainy feel.

Smooth
This finish has a smooth surface and slight shine, created using a physio-chemical process to vapor smooth the surface.

Design Guidelines

Bounding Box

Maximum Bounding Box
284 x 380 x 380 mm (Gray Natural and Black Smooth)
210 x 210 x 360 mm (Black Natural)

Note: Parts covering the exact maximum bounding box dimensions might not be printable due to printer limitations.

Minimum Bounding Box
4 x 4 x 1 mm or X + Y + Z > 9 mm (Gray and Black Natural)
15 x 10 x 5 mm (Smooth)

The bounding box is a 3D imaginary outline of a box that encloses the smallest area occupied by your model. Your model must be within the minimum and maximum bounding box sizes. If the size of the model is close to the maximum bounding box, then the printing orientation will be restricted.
