3.3 Trimming die The second study case was the functional edge of a trimming die for flash trimming of a connecting rod (see Figure 6). The tool material was S355 steel and Nimonic alloy was used as such deposition material. The tool dimensions were 800x350x50mm.

• SDM 1800 module, • process time

1 hour,

• laser power

900 – 1050 W,

• speed 850 mm/min, • amount of powder delivered 12 g / min, • shielding gas argon 5.0.

4. Case studies of DED in cold forming processes The main goal of the DED AM application is to increase the lifetime of the tool, part or component. The materials with high mechanical properties, lower friction properties or lower weight are used for AM applications in the area of cold forming processes. 4.1 Grips for drop weight tower Grips for dropweight tower is not a typical application in the field of forming technology, but a field of mechanical testing. The reason was a demonstration of the whole chain in AM area in COMTES FHT. That means to show the whole process from the part design, topological optimization using structural analysis to the production itself.
