Process description
Vat polymerization was the first additive manufacturing developed in 1986 by Charles hull. it starts with a print plate being lowered to the top of a vat filled with a photoreactive resin. a light source is then used to cure the first layer direct on the build plate. the build plate is then raised so the next layer can be cured directly onto the last. this is repeated until the part is complete. the part then must be put through a washing process, and then a final cure with a strong light.
