Abstract: Polymerizable liquids are described herein which, in some embodiments, can produce 3D printed articles of high resolution and desirable mechanical properties. In one aspect, a polymerizable liquid comprises an acrylate component, a polymeric additive, and a monomeric curing agent, wherein the acrylate component and monomeric curing agent are copolymerizable upon exposure to light. In being copolymerizable, the acrylate component and monomeric curing agent can form a copolymer. As described father herein, the monomeric curing agent can enable further reaction of the copolymer with one or more crosslinking species to link the copolymer with one more polymeric networks.

Abstract: A three-dimensional (3D) printing system for manufacturing a 3D article includes a resin vessel, a build tray, a movement mechanism, a light engine, a housing, a gas handling system, and a controller. The resin vessel includes a transparent sheet on a lower side. The housing defines two chambers including an upper chamber and a lower chamber. The upper chamber is in fluidic communication with the resin contained by the resin vessel. The lower chamber is in fluid communication with a lower surface of the transparent sheet. The controller is configured to (a) operate the gas handling system to reduce and control a partial pressure of oxygen in the upper and lower chambers, (b) operate the movement mechanism and the light engine to form the 3D article in a layer-by-layer manner.
