The majority of commercially available particulate materials in additive manufacturing are single-material systems. Multi-material systems are typically generated by bulk mixing as heterogeneous systems that are difficult to reproduce due to segregation effects during mixing and later deposition in the manufacturing process. This limits the properties of the additively manufactured components. For further application areas of additively manufactured components, it is therefore imperative to produce process-optimized single-material particles in addition to multi-material systems, whereby the production of the material systems and their handling require new process routes. The base materials for powder-based additive manufacturing must meet various requirements for processing, and the particles should be between 70 and 120 \(\upmu \) m in size and have good flowability. These targeted properties also apply to multi-material systems.

摘要

The majority of commercially available particulate materials in additive manufacturing are single-material systems. Multi-material systems are typically generated by bulk mixing as heterogeneous systems that are difficult to reproduce due to segregation effects during mixing and later deposition in the manufacturing process. This limits the properties of the additively manufactured components. For further application areas of additively manufactured components, it is therefore imperative to produce process-optimized single-material particles in addition to multi-material systems, whereby the production of the material systems and their handling require new process routes. The base materials for powder-based additive manufacturing must meet various requirements for processing, and the particles should be between 70 and 120 \(\upmu \) m in size and have good flowability. These targeted properties also apply to multi-material systems.
