Nylon12 – [PA12] – 3D Printing Material
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 material can be found in our Help Center.

Description
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)
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
1.5 mm (Smooth)
0.5 mm (Natural)
1.5 mm (Smooth)
A supported wall is connected at least on two sides of the wall, while an unsupported wall is connected only on one side of the wall. Walls that do not meet the minimum requirements may not survive printing and cleaning processes. Additionally, models may still be rejected based on the wall geometry of the model. Please consider the size of your model and reinforce the walls or add support structures as needed as minimum guidelines will not always be adequate for large models.
Wires
0.8 mm (Natural)
1.5 mm (Smooth)
0.9 mm (Natural)
1.5 mm (Smooth)
A wire is a circular, rectangular or even triangular feature that is thinner in its unconnected directions than its length. A supported wire is connected at least on two sides of the model, while an unsupported wire is connected on one side of the model. Wires that do not meet the minimum requirements may not survive printing and cleaning processes. Additionally, models may still be rejected based on the wire geometry of the model. Please consider the size of your model and reinforce the wires or add support structures as needed as minimum guidelines will not always be adequate for large models.
Details
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)
0.2 mm deep & wide (Natural)
0.3 mm deep & 0.4 mm wide (Smooth)
(0.4 mm high & wide for readable text, logos, and icons)
For text, the ratio between width and depth, should be 1:1 and sans-serif fonts are preferred for line weight consistency.
Escape Holes
4.0 mm (Natural)
10 mm (Smooth)
2.0 mm (Natural)
8.0 mm (Smooth)
Escape holes are necessary to empty the support material of a hollow model. Two escape holes at the opposite ends of the model is optimal for the support removal process. Please consider the size of your model and make the escape holes bigger or add more escape holes as needed as minimum guidelines will not always be adequate for large models.
Clearance
0.6 mm (Natural)
5.0 mm (Smooth)
Clearance is the space between two individual parts in a model. If the space among the individual parts do not meet the minimum clearance, then parts can fuse together or can be difficult to clean. This is important for movable pieces like hinges, gears, etc.
Sprues
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.
Interlocking & Enclosed Parts
Interlocking
Yes (Natural)
No (Smooth)
Enclosed
Yes
Parts in File
Up to 250 (Natural)

Accuracy
Natural: ± 0.2 mm ± 0.5% of the length
Smooth: ± 0.4% (with a lower limit of ±0.2 mm)
