When it comes to fabricating a series of identical objects, the technique of molding is playing an important role. One of the favored materials for the mold is silicone, as it is deformable and therefore forgiving when it comes to extracting complex objects from the mold at the end of the fabrication process. Extracting the object from the mold generally requires deciding for a direction in which the mold pieces can be separated without getting caught in overhanging parts of the object. A careful cut needed to be placed to open the mold. This process, which until now involved manual work from an experienced craftsman, has now been automated. "Until now, silicone molding of complex shapes was a craft that needed years of experience and a skillful hand. You needed to know where to place the cuts ideally and the work was done manually. Our new tool makes this method accessible for everyone," says Bernd Bickel.

The user only needs to upload the desired shape to the computer. The tool then helps in two steps: first, it calculates where the cuts need to be placed for an optimal result. This means that the smallest possible number of mold pieces is used and...
