More Information
Summary:A photoreactive additive manufacturing system comprises a resin tub, a membrane, and a resin pool confined by the resin tub and the membrane. In some embodiments, the membrane comprises a polymeric blend comprising a first polymer and a second polymer, and the first polymer is a fluoropolymer. In some embodiments, the membrane comprises a polymer and an additive to control the free volume of the polymer.
