Beschreibung
Zusammenfassung:	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.
