1. A method for producing three-dimensional objects, comprising:

  • producing a three-dimensional structure by sequential selective curing of layers of a composition curable with visible and/or ultraviolet light into a solid polymeric material by sequential exposure of the individual layers of said polymeric material to UV and/or visible light,producing a three-dimensional object on or inside the three-dimensional structure thus formed, andremoving the three-dimensional structure from on or inside the three-dimensional object, by chemically cleaving the polymeric material and, simultaneously or subsequently, dissolving the polymeric material in a solvent or mixed solvent, and/or melting the material.
