A silicone part made by 3D printing. WACKER, the Munich-based chemical group, has developed a process that enables the printing of three-dimensional silicone objects for the first time. The process is ideal for numerous industrial sectors. It opens up completely new opportunities for developing products in the automotive, medical, household-appliance and lighting industries. Now prototypes with complex geometries can be produced quickly and flexibly, without expensive tools. In the same way, it is possible to produce small series and spare parts that have to be continuously modified to meet changing requirements.
