The invention relates to a method for producing a shaped body using a radiation-induced printing process, characterized in that the shaped body - Is produced from a liquid or viscous material which has a starting component with cycloolefinic groups, a thiol with at least two thiol groups per molecule and an initiator and / or catalyst for the light-induced thiol-ene addition reaction between the thiol groups and a double bond of the cycloolefinic Contains groups, and - The solidification takes place in that light from a radiation source is directed onto an area of a surface of a substrate, a layer of the liquid or viscous material located there being subjected to organic polymerization by the action of radiation and thereby being solidified, whereupon successive further layers of the liquid or viscous material, which are each on the layer of the last solidified material, are solidified with the aid of this radiation source. The invention further relates to a shaped body made of a material which was formed by a photo-induced thiol-ene addition reaction of a thiol compound with at least two thiol groups per molecule to a starting component with cycloolefinic groups, obtainable by the process mentioned, characterized in that the shaped body within a Temperature window from -10 ° C to 80 ° C with a temperature increase of at most 20 K, its storage module will drop by at least 1500 MPa. |
