Polyamide 11 powder for laser sintering and 3d printing: ROLASERIT® PA11-01, PA11-01-BK and PA11-01-CF

PA11 is based 100% on renewable raw materials and is made from castor beans. In contrast to PA12 in laser-sintering, significantly higher elongation at break can be achieved with PA11. The elongation at break in the build plane is up to 45%. Even in the building direction, significantly higher elongation at break of 25%, in some cases even over 30%, is achieved compared to PA12. The material is therefore particularly suitable for applications in which component ductility plays a major role. In addition, the material has the best impact strength values in laser-sintering. Even the notched impact strength is 7.5 kJ/m². The material's processability is comparable to that of PA12.

For the natural-colored variant PA11-01 food contact according to EC No. 1935/2004 and FDA approval is possible.

The material is also available as a black variant PA11-01-BK, with a true black color well suited also for fiber laser.
Carbon fiber-filled variant

AM Polymers also offers the carbon fiber-reinforced PA11-01-CF. This has a very high strength of 74 MPa and a high stiffness of 5,800 MPa. However, with 8.5% elongation at break, the material remains sufficiently ductile to enable flexible features to be realized in the part. Even in the z-direction, with 46 MPa strength and 2,500 MPa Young's modulus, there is no weakening of the material. An HDT B of 190 °C also allows parts to be used at very high temperatures. In contrast to other carbon fiber-filled materials, the material can be refreshed using standard processes and mesh sizes during sieving as a result of a filler size tailored to the grain size. This ensures a constant fiber content and high compound quality.
