About MJF Plastic PA12 – 3D Printing Material
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.

Design Guidelines
Bounding Box
Bounding Box Max
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.
Bounding Box Min
4 x 4 x 1 mm or X + Y + Z > 9 mm (Gray and Black Natural)
10 x 10 x 10 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.
Walls
Supported Wall Thickness Min
0.4 mm (Natural) 1.5 mm (Smooth)
Unsupported Wall Thickness Min
0.5 mm (Natural) 1.5 mm (Smooth)
Wires
Supported Wires Min
0.8 mm (Natural) 1.5 mm (Smooth)
Unsupported Wires Min
0.9 mm (Natural) 1.5 mm (Smooth)
Details
Details Min Embossed
0.2 mm high & wide (Natural)0.3 mm high & 0.5 mm wide (Smooth)
(0.4 mm high & wide for readable text, logos, and icons)
Details Min Engraved

Escape Holes
Single Escape Hole Diameter (Min)
4.0 mm (Natural) 10 mm (Smooth)
Multiple Escape Hole Diameter (Min)
2.0 mm (Natural) 8.0 mm (Smooth)
A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.
Clearance
Min
0.6 mm (Natural) 5.0 mm (Smooth)
Sprues
2 mm thick, attached in at least 2 places per part
Sprues are wires that keep two or more parts together. Parts should be connected with a minimum of two sprues each. Please consider the size of your sprues and increase them as needed as minimum guidelines will not always be adequate for large models. If the sprues are within the guidelines and are broken, but there is no damage to your model, we will still ship them as is.

Accuracy
Accuracy
Natural: ± 0.2 mm ± 0.5% of the length
Smooth: ± 0.4% (with a lower limit of ±0.2 mm)
Smooth: ± 0.4% (with a lower limit of ±0.2 mm)
For example: a product with dimensions of 50 x 50 x 100 mm can be 0.2 mm + 0.005*100 mm = 0.7 mm bigger or smaller in any direction.
