Rapid-prototyping method and radiation-hardenable composition of application thereto

The invention relates to a method for production of three-dimensional objects, comprising the production of a three-dimensional structure, by sequential selective hardening of layers of a composition which may be hardened by visible and/or UV light to give a solid polymeric material, whereupon a thr...

Beschreibung
Zusammenfassung:	The invention relates to a method for production of three-dimensional objects, comprising the production of a three-dimensional structure, by sequential selective hardening of layers of a composition which may be hardened by visible and/or UV light to give a solid polymeric material, whereupon a three-dimensional object is produced using the three-dimensional structure, the three-dimensional structure then being removed out of/from the three-dimensional object, characterized in that the removal of the three-dimensional structure is achieved by chemical cleavage of the polymer material and simultaneous or subsequent dissolution of the materially in a solvent or solvent mixture and/or melting of the material.
