Abstract
A device for producing a 3D-printed active substance-releasing system with active substance depots, such that a radiation source in operation causes a polymerisation of a layer of the base material on the construction platform and that an inkjet printhead incorporates an active substance mixture, which has at least one active substance, into the base material in a locationally selective manner. A trough is provided, in which a base material and a construction platform are arranged, and polymerising selected regions of a layer of the base material on the construction platform and introducing, by means of an inkjet printing method, an active substance mixture, which has at least one active substance, into the base material and/or polymerised base material in a locationally selective manner in order to thereby create active ingredient depots in the active ingredient-releasing system.
