Abstract: A resin cassette for an additive manufacturing apparatus includes (a) a light transmissive window; (b) a circumferential frame connected to and surrounding the window, the window and frame together forming a well configured to receive a light polymerizable resin; and (c) a fluorophore layer in or on the window.

Abstract: A carrier platform for an additive manufacturing apparatus includes (a) a build member having a top portion and a planar build surface, on which build surface an object can be produced by additive manufacturing; (b) an elevator coupler connected to the build member top portion; and (c) a reflector operatively associated with the build surface, the reflector having a reflective surface facing away from the build surface.

Abstract: A resin cassette for an additive manufacturing apparatus is provided. The apparatus has a light engine and a cassette mount operatively associated therewith, with the light engine configured to project an enlarged projected image through the resin cassette when positioned on the cassette mount. The resin cassette includes a light transmissive window configured to pass the enlarged image therethrough. The window has internal structures defining fluid flow passages therein, with the internal structures distributed across the length and width of said window. These internal structure create reflective and/or refractive surfaces within the window. The window includes a circumferential frame connected to and surrounding said window, said window and frame together forming a well configured to receive a light polymerizable resin. The shape of the internal structures is progressively varied (e.g.
