This is a 3d printable prototype of an SLA printer, each part is easily recognizable and many can actually be used in a final SLA 3D printer. SLA stands for stereolithography and is a form of 3D printing involving liquid resin instead of plastic. This resin is hardened by light from a laser or DLP projector (in the case of this model DLP projector with 1080p or higher resolution). This model is recommended for not actually 3d printing the entire piece at one rather printing individual pieces such as the case or the T extrusion arms at once. It is also useful for a basis to design your own SLA printer for a much cheaper price than the cost of online blueprints.
