Precimid1171Pro AF40 is a gray, aluminum powder filled PA12 powder, which is characterized by high rigidity and good metal surface. As described above, a part of the nylon powder is doped with aluminum powder, and printed by SLS technology, so that the printed product is endowed with metallic luster. The mixed aluminum material has high strength and a certain degree of flexibility, so that it can withstand a small impact and resist some pressure when it is bent. Its surface has a rusty, powdery texture and is slightly loose. The mixed aluminum nylon material is suitable for complex models, conceptual models, series of small models (a model with multiple parts) and other functional models. Suitable for models that require a gray appearance or require higher strength than nylon materials.
After a certain test, it is found that when the content of aluminum powder increases from 0 to 50%, the mechanical properties of the finished product show a law of gradual increase and then decrease. According to this law, Yingpu selects the 40% aluminum powder at the inflection point of the mechanical properties. Addition ratio (note: due to different manufacturers’ choice of powder base material and particle size, this rule and conclusion are not universal). In addition, the tensile strength, elongation at break, and impact strength of the sintered parts also increase with the decrease of the average particle size of the aluminum powder.
Laser sintered parts are made from PA3200 GF with excellent material properties:
A typical application is metal-like appearance, heat-loaded parts.
The most prominent feature of printed parts using Precimid1171Pro AF40 is high hardness, metal appearance and good post-processing possibility, which is especially suitable for application scenarios that have strict requirements on metal appearance and parts processing accuracy. The surface of the part can be easily refined by grinding, polishing or coating. Through the cutting and fracture effect of aluminum filler, the difficulty of secondary processing of laser sintering printed parts is simplified. In addition, due to the addition of metal powder, the processed parts also have better rigidity and certain thermal conductivity.
At present, this type of material is mainly used in the manufacture of hard parts requiring metal appearance in automobile manufacturing, parts manufacturing required by secondary machining, parts manufacturing required by thermal load work, and the manufacturing of parts such as customized production tools and fixtures.
