3D printing workshop #Terressens

The 3D model is imported into a preparation program called a slicer (as with filament printing). The slicer cuts the model into horizontal layers(slices) and generates a file containing instructions for the printer, indicating how each layer is to be printed.

The photosensitive resin is poured into the machine's reservoir. It can be of different colors and properties, depending on the specific needs of the project.

The printing platform is positioned above the resin tank. The distance between the resin surface and the bottom of the platform is adjusted according to the thickness of the layer to be printed.

Stereolithography uses ultraviolet (UV) light to cure the liquid resin. A laser or UV light source is directed at the resin surface, following the path defined by the layer file.

When the UV light strikes the resin, it causes polymerization, transforming the liquid resin into a solid material. The platform is then lowered by the height of the next layer, and the process is repeated to build the next layer on top of the previous one.

The previous two steps are repeated until all the layers of the 3D model have been printed.
