    Abstract: Provided herein are methods of forming a three-dimensional object, which may be carried out by: (a) forming a three-dimensional intermediate by polymerization of a polymerizable liquid in an additive manufacturing process, the polymerizable liquid comprising a light polymerizable component; then (b) contacting at least a portion of the three-dimensional intermediate to a penetrant fluid, the penetrant fluid carrying a solidifiable component, the contacting step carried out under conditions in which the solidifiable component penetrates into the three-dimensional intermediate; (c) optionally but preferably separating the three-dimensional intermediate from the penetrant fluid; and then (d) solidifying and/or curing the solidifiable component in the three-dimensional intermediate to form the three-dimensional object.Provided herein are methods of forming a three-dimensional object, which may be carried out by: (a) forming a three-dimensional intermediate by polymerization of a polymerizable liquid in an additive manufacturing process, the polymerizable liquid comprising a light polymerizable component; then (b) contacting at least a portion of the three-dimensional intermediate to a penetrant fluid, the penetrant fluid carrying a solidifiable component, the contacting step carried out under conditions in which the solidifiable component penetrates into the three-dimensional intermediate; (c) optionally but preferably separating the three-dimensional intermediate from the penetrant fluid; and then (d) solidifying and/or curing the solidifiable component in the three-dimensional intermediate to form the three-dimensional object.

    Abstract: An epoxy dual cure resin useful for additive manufacturing of three-dimensional objects includes: (i) a photoinitiator; (ii) monomers and/or prepolymers that are polymerizable by exposure to actinic radiation or light; (iii) optionally, a light absorbing pigment or dye; (iv) an epoxy resin; (v) optionally, but in some embodiments preferably, an organic hardener co-polymerizable with the epoxy resin; (vi) optionally but preferably a dual reactive compound having substituted thereon a first reactive group reactive with said monomers and/or prepolymers that are polymerizable by exposure to actinic radiation or light, and a second reactive group reactive with said epoxy resin (e.g., an epoxy acrylate); (vii) optionally a diluent; (viii) optionally a filler; and (ix) optionally, a co-monomer and/or a co-prepolymer. Methods of using the same in additive manufacturing are also described.

    Abstract: Provided herein is a polymerizable liquid composition useful for additive manufacturing, which composition may include: (i) a free radical photoinitiator; (ii) monomers and/or prepolymers (e.g., reactive diluents) that are polymerizable by exposure to actinic radiation or light, optionally wherein some or all of said monomers and/or prepolymers comprise one or more acid-labile or base-labile groups; (iii) a crosslinker comprising one or more acid-labile or base-labile groups; and (iv) a photoacid generator or a photobase generator, wherein said free radical photoinitiator and said photoacid generator or photobase generator are, or are selected to be, activated by light at different ranges of wavelengths or intensities. Methods of forming a three-dimensional object with the composition, and articles so formed are also provided. Methods of removing a portion of the article by dissolving in a polar or non-polar solvent are further provided.

    Abstract: A method of forming a three-dimensional object by bottom-up three-dimensional fabrication by irradiating a polymerizable liquid to produce the three-dimensional object, is described. In the method: (i) a Lewis acid or an oxidizable tin salt (e.g., stannous octoate) is included in said polymerizable liquid in an amount effective to accelerate the formation of said three-dimensional object during said fabrication; and/or (ii) the three-dimensional object is irradiated after forming to further polymerize unpolymerized material remaining in the three-dimensional object.

    Abstract: A method of forming a three-dimensional object, which method includes a cleaning or washing step, is carried out by: (a) providing a carrier and a fill level, and optionally an optically transparent member having a build surface defining the fill level, the carrier and the fill level having a build region therebetween; (b) filling the build region with a polymerizable liquid, the polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from the first component; (c) irradiating the build region with light, to form a solid polymer scaffold from the first component and also advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object and containing the second solidifiable component carried in the scaffold in unsolidified and/or uncured form; (d) washing the three-dimensional intermediate; and (e) concurrently with or subsequent to the irradiating step, and/or the washing step, solidifying and/or curing the second solidifiable component in the three-dimensional intermediate to form the three-dimensional object.

    Abstract: A method of forming a three-dimensional object is carried out by: (a) providing a cyanate ester dual cure resin; (b) forming a three-dimensional intermediate from said resin, where said intermediate has the shape of, or a shape to be imparted to, said three-dimensional object, and where said resin is solidified by exposure to light; (c) optionally washing the three-dimensional intermediate, and then (d) heating and/or microwave irradiating said three-dimensional intermediate sufficiently to further cure said resin and form said three-dimensional object. Compositions useful for carrying out the method, and products made from the method, are also described.
