Voxeljet has used one of its 3D printers to create a sand mold that is being used by students at Germany’s University of Bayreuth to build a laminate template for the seat of a race car.

The seat mold was printed at the company’s service center in several individual components that were subsequently assembled. Because the molds will be used multiple times, Voxeljet recommended that they be filled and sanded prior to laminating, and then a separation layer be applied. During the laminating process, carbon fiber mats are placed over the printed mold and coated with epoxy resin. This process is repeated until the desired material thickness has been achieved. Finally, the seat is put in a vacuum-packed plastic bag and cured at room temperature.
