MJF Materials

PA 12
This engineering grade thermoplastic produces high-density parts with extreme dimensional accuracy and fine detail for functional prototyping and final parts. This strong thermoplastic is ideal for complex assemblies, lattice structures, housings, enclosures and connectors, and optimal for post finishing processes. PA 12 also has excellent chemical resistance to oils, greases, aliphatic hydrocarbons and alkalies.
