Polyamide 11 - PA11

Polyamides are one of the most important groups in the field of engineering plastics. In powder bed fusion, polyamides dominate the market in the form of PA12 and PA11.

High ductility and maximum impact strength

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.

In addition to the natural-colored variant PA11-01, for which FDA approval is possible, the material is also available as a black variant PA11-01-BK, with a true black color.

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.
