Unconventional, cleanable mold division with indirect additive manufacturing
Indirect additive manufacturing offers some great advantages with the printing of molds and cores, such as the possibility to produce very complex geometries at moderate costs. In this context, the following should be noted: The more complex the mold, the more complex is the subsequent cleaning process to remove sand build-up. Here, the layer construction method offers a possible solution, which additionally offers the prospect of a fully automated process.
In the project Schichtbau², individual, load-bearing layers with easier to clean geometries are created by means of a mathematically topology-optimized division of the mold. This creates favorable conditions for the subsequent processes up to casting. The layers are produced in a binder jetting process and can be cleaned automatically after the printing process and then stacked.
