Stereolithography

Stereolithography (SL) is one of the first 3D printing / prototype construction procedures. It makes it possible to manufacture precise components from plastics. In this process, the initially liquid plastic, which initially consists of monomers, is polymerized with a laser and thus solidified. The monomers polymerize at a specific wavelength so that the laser emits exactly that wavelength to start polymerization. By lowering the component platform within the resin basin, the currently solidified contour is lowered by a further layer into the resin bath so that the next layer can be exposed.

The accuracy of the component is determined by the mechanical precision of the lowering so that a very high accuracy can be achieved. The components are subsequently irradiated again from all sides with a light of the required wavelength, which further hardens the surface.

The subsequent finishing of the components offers various possibilities for further applications. Due to its high precision, stereolithography is mainly used for the production of master models in vacuum casting. The master model creates a negative in the silicone.
