PA11 CF is a material for high performance applications. It is a material based on PA11 Onyx, additive with short carbon fibre to improve mechanical strength in tensile and bending, as well as to provide parts with increased stiffness.

It has one of the best strength-to-weight ratios among SLS 3D printing materials, making it also one of the most versatile and high-strength materials available for SLS 3D printing.

Comparison

PA11 CF almost doubles the tensile strength (81 MPa vs. 48 MPa) and flexural strength (100 MPa vs. 62 MPa) compared to PA11 Onyx. It also has a higher stiffness, with an elongation at break of 24%.

Like PA11 Onyx and PA11 ESD, PA11 CF requires the use of nitrogen during printing. Likewise, a Sinterit Studio Advanced Software licence is required to use this material.

PA11 CF is sensitive to moisture, so it must be stored properly in a dry environment. In the event of moisture pick-up, it can be dried at 100°C for 6h. Depending on the degree of humidity or the length of time stored in poor conditions, the material may not recover its original properties.

After each use, the material needs to be refreshed by 40 %.
