DuraForm PA polyamide nylon plastic, used for functional testing and low- to mid-volume rapid manufacturing.

The DuraForm PA rigid Selective Laser Sintering (SLS) material has fantastic mechanical stiffness and durability for parts that require actual testing. DuraForm PA is a good general prototyping material and is chemically resistant to akalines, hydrocarbonates, fuels and solvents. 

Nylon parts built using the SLS or LS process produce excellent tab strength, gears, impellers and work well in underhood automotive environments, where they may come in contact with heat or chemicals.

Parts can be further annealed to improve flex, thermal properties and/or sealed for applications in which the parts may be under pressure, water or in contact with petroleum based products.

Due to the nature in which SLS and LS models are produced, DuraForm PA makes an excellent choice for Additive Manufacturing (AM). Multiple parts can be built quickly with a high level of dimensional repeatability.  The bright white nature of the material can be desirable, but parts can be painted or dyed right off the machine (paint is recommended over dye).
