Harder 3D-printed tools – Researchers from Dresden introduce new process for hardmetal industry
Extremely hard tools are required in forming technology, metal-cutting and process engineering. They are conventionally made by powder pressing. Although this achieves a high degree of hardness, it is often necessary to carry out a complex and therefore expensive post-processing. Additive manufacturing enables complex geometries, but has been limited in terms of hardness and component size so far. Researchers at the Fraunhofer IKTS in Dresden have now adapted the 3D printing process Fused Filament Fabrication for hardmetals. The development meets all requirements for the first time.
