    摘要： A continuous liquid interface production system includes a source of optical stimulation. The system includes a vessel configured to retain a pool or film of optically sensitive monomer and a substantially optically transparent plate retained by the vessel. The optical stimulation is directed through the plate and into the pool or the film based upon a sliced 3D model of the part. The system includes source of reaction inhibitor wherein the substantially optically transparent plate allows the reaction inhibitor to permeate through the plate and into the pool or the film such that a sufficient amount of reaction inhibitor is within the pool or the film to create a zone proximate the plate that prevents polymerization therein. A build platen is configured to be at least partially immersed into the pool or the film and above the zone as a part is initially being built, wherein a build platen actuator moves the build platen away from the pool or the film in a direction substantially normal to a top surface of the plate. A relative movement actuator provides relative movement between the plate and the part in a direction substantially parallel to the top surface of the plate such that a viscosity pump effect is created that forces monomer between the part being built and the plate.

The system includes source of reaction inhibitor wherein the substantially optically transparent plate allows the reaction inhibitor to permeate through the plate and into the pool or the film such that a sufficient amount of reaction inhibitor is within the pool or the film to create a zone proximate the plate that prevents polymerization therein. A build platen is configured to be at least partially immersed into the pool or the film and above the zone as a part is initially being built, wherein a build platen actuator moves the build platen away from the pool or the film in a direction substantially normal to a top surface of the plate. A relative movement actuator provides relative movement between the plate and the part in a direction substantially parallel to the top surface of the plate such that a viscosity pump effect is created that forces monomer between the part being built and the plate.
