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.

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%.
