    摘要： An apparatus useful for rapidly producing at least one object having a contoured surface portion from a light-polymerizable resin is provided. The apparatus includes (a) a window containing an inhibitor of polymerization, on which window a coating of light polymerizable resin can be placed, with the inhibitor of polymerization forming a first dead zone of unpolymerizable resin in the light polymerizable resin; (b) a polymerizing light source operatively associated with the window and positioned for projecting polymerizing light through the window; (c) a controller operatively associated with said light source and configured to pattern and project said polymerizing light at a first light dosage sufficient to form the object in the resin under stationary conditions, while spatially modulating the first light dosage so that the first dead zone is spatially contoured in thickness, to produce a first contoured surface portion on each object, which first contoured surface portion is in contact with the first dead zone of unpolymerizable resin.

    摘要： A method of cleaning residual resin from an additively manufactured object, includes: (a) enclosing an additively manufactured object in an inner chamber of a centrifugal separator, the additively manufactured object including a light polymerized resin with a surface coating of viscous, unpolymerized, residual resin; (b) flooding the chamber with a volatile organic solvent vapor without contacting liquid organic solvent to the object, the vapor present in an amount sufficient to reduce the viscosity of the residual resin; and (c) spinning the additively manufactured object in the chamber to centrifugally separate at least a first portion of the residual resin from the object.

    摘要： A method of forming a dual cure three-dimensional object by additive manufacturing may be carried out by mixing a first precursor liquid and a second precursor liquid to produce a polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component (e.g., a second reactive component) that is different from the first component (e.g., that does not contain a cationic photoinitiator, or is further solidified by a different physical mechanism, or further reacted, polymerized or chain extended by a different chemical reaction). In the foregoing: (i′) at least one reactant of the second solidifiable component is contained in the first precursor liquid, and (ii′) at least one reactant or catalyst of the second solidifiable component is contained in the second precursor liquid. Once mixed, the three-dimensional object may be formed from the resin by a dual cure additive manufacturing process.

    摘要： An adhesion barrier is comprised of, consists of, or consists essentially of a sheet having a top surface and a bottom surface. The sheet includes either (i) interconnected links or (ii) interconnected, vertically aligned, partitions. The links form pores or the partitions form pores, with the pores extending from the top surface through the bottom surface. The sheet is comprised of, consists of, or consists essentially of a flexible or elastic polymer.
