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.
A method for additive manufacturing of a three-dimensional workpiece (1), the method comprising changing a thermoplastic material by heating to a liquid phase, selectively applying the thermoplastic material in the liquid phase at locations predetermined by the shape and the dimensions of the workpiece (1), wherein the workpiece (1) is built up in layers on a substrate carrier (2), and thereafter, to cool and solidify the material, moving the workpiece (1) which is built up in layers on the substrate carrier (2) from a construction chamber (3) into a cooling chamber (4) which is separated from the construction chamber (3).
An apparatus for the additive manufacturing of a three-dimensional workpiece (1) from a thermoplastic material which is liquefied by heating, the apparatus comprising a construction chamber (3) for receiving a substrate carrier (2, 2′) on which the workpiece (1) can be built up in layers, and a cooling chamber (4) which is arranged adjacent to the construction chamber (3) so that the workpiece (1) which is built up in layers on the substrate carrier (2) can be moved for cooling and solidifying the thermoplastic material from the construction chamber (3) into the cooling chamber (4).
