MJF Nylon PA12
Nylon PA 12 is one of the most common plastics used in industrial 3D printing because of it's balance of excellent material properties, fine detail and low cost. This versatile plastic is flexible, has high impact resistance, is UV and water resistant, and is certified biocompatible. These qualities make it optimal for a wide range of uses in various industries including automotive, healthcare, consumer goods, and aerospace.
HP Nylon PA12 is printed on the HP Multi Jet Fusion 5200, with production speeds up to 10x faster than comparable technologies. This material is ideal for rapid prototyping and low-to-mid-range manufacturing.

Raw: This is how the parts come out of the printer after being air-cleaned. The color is a powdery gray, that may be inconsistent in areas that are harder to reach by the air blaster used to remove printing powder. This is a great low-cost option for non-visual end-use or rapid prototyping.
Black: Black dye gives the part an engineering-grade finish with a matte look and feel. No material is removed and the original geometry of the part is retained.
Vapor Smoothing: Vapor Smoothing is a physio-chemical process that smooths the surface of PA12, giving a look and feel comparable to injection-molded parts. The process is non-line-of-sight and can smooth both internal and external surfaces of parts, with no degradation of a parts’ dimensional accuracy, and improves some mechancial properties such as increased water resistance. This treatment is the best option for customer-facing parts, or for conditions where the part will be subject to consistently wet conditions.
Produces strong, high-density parts with near-isometric properties on x-y and z axis.
Excellent chemical resistance to oils, greases, alphalitic hydrocarbons, and alkalies.

Thin and long parts, as well as large flat surfaces, may be prone to warping. Refer to our design guide to minimize the possibility of deformation.
Consider hollowing or adding internal lattice structure to large solid pieces to improve accuracy and minimize cost. Refer to our design guide for details.
Hinges, sockets, and linked parts (such as chain mail) can be integrated into the design. See our design guide for details.
HP Multi Jet Fusion Manufacturing Standards
With Multi Jet Fusion, a dimensional accuracy of +/- 0.3% with a lower limit of +/- 0.3% is consistently achievable across prints.
Please note that parts outside of the specifications in our design guide risk being out of tolerance. Please refer to these guidelines to ensure you achieve the best possible result. The main issues to be aware of are how to minimize the risk of warping for large flat surfaces, and how to avoid sink or shrinking on thick-walled parts. Our professionally-trained technical team is always happy to answer any questions you may have about designing for MJF.
