    "protocol": "VP consists of selective curing of liquid photo-sensitive material using light/radiation. Light is projected onto the photopolymer, following a pattern defined by a CAD file. The process selectively cures the photopolymer, resulting in the formation of the final part. Typical material systems consist of acrylate or epoxy-based monomers, photoinitiators, diluents, light absorbers, and radical inhibitors. Low viscosity resins (0.25-10 Pa.s) are recommended to avoid damaging printed features during the recoating process. Factors influencing the properties of VP parts include layer height, build orientation, exposure time, light source intensity, resin viscosity, reactivity, and photoinitiator concentration."
