RFH has developed a special supporting SLA light-curing 3D printer in addition to the already mature high-power ultraviolet laser. The 3D printer, which uses a UV laser and a liquid UV-cured photopolymer called "photoresin" to print parts, provides additional services to customers.

UV laser cold sources are an essential component in SLA 3D printing technology. They provide the necessary energy to solidify liquid resin into a solid object layer by layer.
