Description

Additive manufacturing (AM) has become of major interest in the tooling industry because of its opportunity to manufacture parts of complex shape or with internal structures such as cooling channels. Nevertheless, the application of AM-processes for the manufacturing of tools is often discarded because processable materials that are suitable for the high demands on strength, wear resistance and thermal conductivity are not yet available. Furthermore, AM costs might exceed that of conventional manufacturing in a way that the benefits of AM are amortized. To break down these barriers a hybrid manufacturing approach was developed with the best of both worlds. By using indirect AM of sand molds via binder jetting technology and state of the art casting process, tools with complex, conformal cooling channels have already been manufactured. Within the new hybrid AM approach, the functional areas are coated using Laser Metal Deposition (LMD) and the latest of AM tool steel powder development to even increase the performance of these tools.
