96557 - Multi Material Tool Manufacturing With Plasma Metal Deposition 

As part of the H2020 project MULTI-FUN, RHP is developing the Plasma Metal Deposition (PMD®) process for the production of die-casting tools with conformal cooling for better heat dissipation. This reduces the cycle time in die casting and therefore enhances the overall process efficiency.

Conformal cooling is well known for small tools produced by the L-PBF process, but is limited in size and material. The PMD® process offers the possibility to produce large parts needed in industrial tooling. With RHPs Metal 3D Printer (M3DP) parts up to 2 meter in length and 0.8 m in width or height, respectively can be produced. For parts with higher complexity the system has a tilt-turn table. Furthermore, the process is multi-material capable, several feedstocks such as wire and powder can be used, and hybrid production is possible. The developments shown include various material combinations such as Cu-based MMCs with steel to further improve thermal conductivity and hybrid production as well as conformal cooling.

Within the scope of this study, the quality of the interfaces between the different materials used will be investigated by use of thermal diffusivity measurements to demonstrate the performance in terms of heat dissipation. Conformal cooling and its limitations regarding PMD-processing are investigated as well.
