Stereolithography (SLA / DLP)
for filigree structures & smooth surfaces
Very precise 3D printing thanks to this well-proven technology
Stereolithography allows us to create highly precise and filigree 3D printing models that are characterized by their level of detail and a particularly smooth surface.
Stereolithography (SLA / DLP) – The manufacturing process
During the stereolithography process, light-curable plastics are cured in thin layers by a laser. These plastics are photopolymers – for example epoxy resin, acrylates, or elastomers – and they are used in their liquid form. The component is created as followed: A wiper evenly distributes the plastic on an existing layer, then a laser cures this new layer.
Subsequently, the build platform is lowered by some millimetres and then retracted. After that, a new layer is printed. This way, the component is constructed layer by layer. The SLA technology requires supporting structures, because otherwise the component would float around in the vat. Afterwards, the supporting structures are mechanically removed from the component.
