MJF PA12 Nylon is a robust thermoplastic with excellent mechanical properties. Engineered to produce end-use parts and functional prototypes, this strong, accurate, temperature, and chemically resistant material is ideal for volume production, replacing injection moulded parts.


Mechanical properties

Durable, strong and mechanically stable. Due to the smaller particle size, MJF PA12 Nylon produces parts with higher density and lower porosity than SLS.

Chemical resistance

MJF PA12 delivers good chemical resistance to water, oils, greases, aliphatic hydrocarbons, and alkalies. MJF parts are compatible with most paints, primers and adhesives.


MJF PA12 parts with 1mm wall thickness display flexibility while thicker features, over ~3mm have higher stiffness. The versatility of PA12 material makes it ideal for dynamic applications.

Temperature resistance

MJF PA12 Nylon parts have good temperature resistance. Thick parts will remain dimensionally stable in temperatures close to 175 °C, while thin parts will start to soften and lose their shape when temperatures exceed 95°C.


All MJF PA12 Nylon 3D prints start their life with a ‘Natural Grey’ finish before post-processes alter their appearance and surface properties. MJF PA12 offers several finishes to meet varied requirements when considering different polymer components’ desired aesthetic and mechanical properties.
