Abstract
A method for producing an article in which a layer with a radically cross-linkable resin is selectively crosslinked at least partially. This takes place according to a selected cross section of the article to be formed by means of selective application of a radical initiator. The at least partially crosslinked material is added on layer by layer to a carrier or to previous layers bonded to the carrier. A system that is suitable for carrying out the method according to the invention has a substrate, a control unit, an application unit for applying the resin to the substrate, an application unit for applying an initiator to the resin, an energy exposure unit and a contacting unit.
