The SLA 3D Printer uses a UV laser that applies the shape of an object to the surface of a photopolymer container. The resin then hardens to form the individual layers of the 3D printed model. This process is repeated until a complete 3D printed object is created.
How does UV resin 3D printing work?
The liquid polymer we use is UV sensitive. When struck by a computer-controlled UV laser, the resin will change from a liquid to solid state. Basically, the laser “draws” the outlines of the print onto the resin layer and hardens the parts that it touches. The parts that are not touched by the laser will remain liquid.
How do resin Orinters work?
A resin 3D printer is a machine that holds a vat of photosensitive liquid resin and exposes it to UV LED light beams layer-by-layer to harden the resin into a plastic 3D model. The technology is called SLA or Stereolithography and can provide 3D prints with extremely fine detail at a 0.01mm layer height.
Why is UV resin toxic?
They can create contact dermatitis, which is a surface rash that could develop into an allergy if you expose yourself to resin for long periods of time. Resins also naturally give off fumes, and unless you work in a well-ventilated area, molecules from the fumes will get into your lungs and cause irritation there, too.
Are resin shot glasses safe to drink from?
ArtResin has been deemed safe for food contact once it has cured, but please keep food or beverages well away from ArtResin in its pre-cured liquid form. ArtResin is NOT edible or potable in either liquid or cured form.
