Laser Generation on a Hybrid Blank The optimal distribution of a volume body in hybrid-blank and laser-generated volume is implemented on CAD on the basis of the 3D data provided by the customer. In the following example, the procedure is represented in detail. The volume of the original part in the base area is very simply producible conventionally. For this reason, a solution for cost optimization is decided on in discussion with the customer. In this case, the solution is a hybrid version. The customer therefore provides a conventionally manufactured blank and thus saves, in this example, approx. 50% of the production costs for his optimally-cooled, contourclose tool.

As can be seen here, the cutting plane is selected maximally far up. It is very important that both parts consist of identical material. In this way differences in the thermal expansion coefficient are avoided and thus the occurrence of stresses within the tool. In case of non-suitable material pairing, stress cracks can result in case of large component parts, due to the very uniform grain texture of 1.2709.

In the section model displayed here, the finished overall structure is clear. The transition area from blank to laser-generated structure can only be identified with the nonprocessed scope due to the uniform, laser-generated grain texture.
