Hybrid Process Chain from Die Casting and Additive Manufacturing
- 6 Downloads
The Fraunhofer Institutes IWS and IWU as well as Edag combine the high productivity of die casting and free shaping in additive manufacturing. This reduces the manufacturing costs of previously additive components and increases the complexity of die cast components. This makes the process interesting for automotive applications.
Additive manufacturing processes such as Laser Beam Melting (LBM) or Laser Metal Deposition (LMD) offer the advantage of tool-free, near net shape production of complex geometries. The production of geometrically complex, topology-optimized components up to small batches is particularly interesting for aerospace, medical technology, tooling industry and increasingly for the automotive industry. Despite the variety of advantages, additive manufacturing processes are still slow to enter industrial production. The main reasons for this are relatively long production times and therefore high production costs.
In contrast to additive manufacturing, high quantities...
