Stereolithography starts by taking a model that is loaded from a virtual 3D file. Using a special programming language, the model is sliced into thin horizontal layers.The support structures are then generated that are needed to correctly attach the part to the machine’s platform.
The stereolithography machine has a tank full of epoxy resin, inside which there is a platform supported on a vertical mechanical axis. Above the tank there is a laser, which is used to polymerise or harden the resin.
In the initial step of the process, a fine layer of resin is exposed above the platform.
The laser beam then traces out the first layer of the model on the surface of the liquid resin, which causes it to polymerise.
After the layer has hardened, the platform is lowered, once again exposing a thin layer of liquid resin on the surface of the tank, ready for the next layer of polymerisation. This process is then repeated, printing layer after layer until the entire three-dimensional object has been formed. The platform is then automatically raised to drain off the excess resin and remove the part. The supports are subsequently removed manually and any traces of liquid are cleaned away. Finally, the surface is further cured in an ultraviolet oven.
