Abstract
The invention relates to a method for the additive manufacturing of a three-dimensional workpiece, in the case of which a thermoplastic material is transferred into a liquid phase by heating and is applied selectively to locations which are predetermined by the shape and the dimensions of the workpiece, wherein the workpiece is constructed in layers on a substrate carrier. According to the invention, in order for the material to be cooled and hardened, the workpiece, which is constructed in layers on the substrate carrier, is moved from a heated construction chamber into a cooling chamber, which is separate from the construction chamber. The invention also relates to an apparatus for the additive manufacturing of a three-dimensional workpiece.
