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 unitfor applying an initiator to the resin, an energy exposure unit and a contacting unit. 用于制造物件的方法，其中具有可自由基交联树脂的层选择性地至少部分交联。这根据要形成的物件的所选截面通过选择性施加自由基引发剂进行。所述至少部分交联的材料以逐层形式附加到载体上或与载体接合的先前层上。适合于进行本发明方法的系统具有基底、控制单元、将树脂施加到基底上的施加单元、将引发剂施加到树脂上的施加单元、能量作用单元和接触单元。
