Device and method for the additive manufacturing of a three-dimensional workpiece

A device for additive manufacturing of a three-dimensional workpiece, comprising:

• a build chamber;
• at least one printhead;
• a receiving device configured to receive the three-dimensional workpiece;
• an air-circulation system configured to control a temperature of and conveying a gaseous fluid;
• an adjustment device including an x-y axis system with a printhead receptacle and a z-axis system;
• wherein the air-circulation system includes a device configured to control the temperature of and conveying the gaseous fluid, an inlet device including at least two inlet openings connected to the build chamber, and an outlet device, wherein the outlet device is integrated in the z-axis system and is disposed in such a way that it can be adjusted using the z-axis system.
