The US company DDM Systems from Atlanta, a spin-off from the famous Georgia Tech University, has submitted an additive manufacturing process for ceramics. The nominated product 'Lamp System CPT6060' makes it possible to shorten the investment casting process from twelve to six process steps. The jury was impressed by the high number of more than two million parallel UV light beams during photopolymerization and the extremely high accuracy of ten micrometres achieved with ceramic mould dimensions of up to 600 x 600 x 450 cubic millimetres. The nominated product uses 3D printing to create high-precision integral cored shell molds directly from digital data sets. This makes rapid prototyping and series production possible in a single system. According to DDM Systems, this high-tech process can reduce previous manufacturing costs by 60%.
