Abstract
Multi-material membranes for use in vat polymerization printers. The membranes include a fluorinated ethylene propylene (FEP) or polyolefin polymer film bonded to a layer of silicone rubber. The layer of silicone rubber is coated to reduce its surface energy. Coatings such as a silicone elastomer or polytetrafluoroethylene (PTFE)-based material may be used. The coatings are preferably sprayed on and allowed to cure or dry after the FEP or other film has been bonded to the layer of silicone rubber.
