Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a coated object (102) by means of additive manufacturing in a vacuum, and to a device (100) for producing a coated object. The method comprises forming a first polymer layer on a workpiece and/or on a print bed (106A). A first coating layer is formed on at least one part of the first polymer layer by means of vacuum gas-phase deposition. A second polymer layer is formed on at least one part of the first polymer layer and/or the first coating layer, wherein the second polymer layer is formed before, during or after forming the first coating layer. The first polymer layer, the first coating layer and the second polymer layer are formed in a vacuum at a gas pressure of less than 1 mbar.
