Materials
- PA12
Nylon 12
Grey polyamide 12, the standard SLS material, has 50 MPa tensile strength and holds dimensions and fine detail well.
plus any RAL colour - PA12 White
Nylon 12 White
PA12 White has mechanical properties close to grey PA12 and is used for parts that are on show or that need to be dyed in colour.
plus any RAL colour - PA12 Tough
Nylon 12 Tough
PA12 Tough is a more ductile PA12 with 25% elongation at break and almost double the Izod impact strength, and it warps less on wide parts.
plus any RAL colour - PA11
Nylon 11
Polyamide 11 is made from castor oil and has 40% elongation at break, so it suits parts that bend or take impacts.
plus any RAL colour - PA12 GF
Nylon 12 GF
PA12 GF is glass-filled, so it is stiffer and more stable in heat than PA12, but also more brittle.
plus any RAL colour - PA11 CF
Nylon 11 CF
Black PA11 filled with carbon fibre is the stiffest and most heat-resistant material in the range, and its properties depend on how the part is oriented.
plus any RAL colour - TPU 90A
TPU 90A
TPU 90A is a thermoplastic elastomer with a hardness of 90 Shore A, used for flexible parts such as gaskets, dampers, handles and grippers.
2 colours - PP
Polypropylene
The powder is true polypropylene, ductile and light, and parts made from it resist acids, bases and solvents and can be welded to other PP parts.

Comparison
Stiffness and elongation at break
A stiffer material deflects less under load, but breaks sooner when bent. On the chart, the glass and carbon fibre materials sit to the right, and PA11 and PA12 Tough, which take large deformations, sit at the top.
