The StereoLithography Apparatus, SLA, 3D printer, available at the rapid manufacturing infrastructure of CERTH-HIT, is able to produce highly dimensional accurate parts with high quality finish. SLA  technology, historically is the first technology of 3D printers. The system uses a low power laser diode to cure a resin with the photopolymerization process. The 3D printer is a second-generation, low cost, desktop printer. The minimum layer thickness of the printer is 25µm, the build volume is 145×145×175 mm³, and the laser spot diameter is 140µm. The materials available for the 3D printer are a multi-color resin, engineering materials with different material properties (e.g. stiffness, strength), castable materials and biocompatible materials. The main application of the SLA printer at CERTH-HIT is for construction of brackets for the placement of sensors on vehicles, prototype product’s shells and for the development of HMI devices. The SLA 3D printer was acquired in the frame of the “PROMYTHEAS” national project.
