SLS 3D printing powder made of polyamide 11 reinforced with short carbon fibre.

Sinterit is a Polish manufacturer recognised as a pioneer in the development of affordable SLS 3D printing solutions. In addition to a complete range of equipment, both compact and industrial, it also has the widest range of optimised materials in its segment.

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%.

Thanks to these excellent mechanical properties, Sinterit's carbon fibre reinforced PA11 is a viable alternative to aluminium and engineering plastics in many applications. It is widely used in the aerospace and automotive sectors.

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 %.
