Abstract: A composite article useful in additive manufacturing typically includes: (a) optionally, but preferably, a base; (b) at least one three-dimensional lattice support connected to the base (when present); (c) at least one three-dimensional object, the object having a bottom surface portion, a top surface portion, at least one upright segment, and optionally at least one overhanging segment (e.g., a bridging segment; a cantilevered segment, etc.); (d) interconnecting supports connecting (i) each the at least one overhanging segment to the three-dimensional lattice and/or (ii) each at least one upright segment to the three-dimensional lattice; and (e) optionally, but in some embodiments preferably, a plurality of elongate stand-off supports interconnecting the bottom surface portion of each the three-dimensional object to the base.

Abstract: A dental model, includes (a) an upper segment, said upper segment having a shape corresponding to at least a portion of a dental arch of a human patient; (b) a base segment having an external surface and a bottom surface; (c) at least one internal cavity formed in said base segment, and optionally said upper segment, said at least one internal cavity extending through said bottom surface; and (d) at least one wash channel extending from said external surface of said base segment through said base segment and into said at least one internal cavity.

Abstract: A method of making at least one three-dimensional object by additive manufacturing, including: (a) producing, on a carrier platform, by bottom-up stereolithography from a single batch of polymerizable resin, a composite article comprising and produced in the sequence of: (i) an open lattice layer on the carrier platform; then (ii) a frangible layer on the lattice layer; and then (iii) at least one three-dimensional object on the frangible layer; then (b) cleaning the composite article with a wash liquid while on the carrier platform; (c) optionally separating the composite article from the carrier platform; and (d) optionally further curing the composite article; and then (e) separating the at least one three-dimensional object from the lattice layer by cutting or breaking the frangible layer.
