The StereoLithography Apparatus, SLA, 3D printer, available at the rapid manufacturing infrastructure of C.E.R.T.H.-H.I.T., 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 C.E.R.T.H.-H.I.T. comprises the construction of brackets for the placement of sensors on vehicles and of prototype product’s shells, while also being used for the development of H.M.I. devices. The SLA 3D printer was acquired in the frame of the “PROMYTHEAS” national project.
