Abstract: A build plate for a three-dimensional printer includes a rigid, optically transparent, gas-permeable planar base having an upper surface and an opposing lower surface; a gas permeable adhesive layer on the base upper surface; and a flexible, optically transparent, gas-permeable sheet having upper and lower surfaces, the upper surface comprising a build surface for forming a three-dimensional object, the sheet lower surface positioned on the adhesive layer opposite the base.

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 groups; (iii) a chain extender, optionally wherein said chain extender comprises one or more acid-labile groups; and (iv) a photoacid generator, wherein at least one of said monomers and/or prepolymers, or said chain extender, comprises one or more acid-labile groups, and wherein said free radical photoinitiator and said photoacid 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.
