Abstract: A method for producing a workpiece includes: placing a workpiece holder on a base support of a support system with a positioning element in an additive manufacturing device, the lower side of the workpiece holder having a first positioning device, the positioning element and first positioning device forming a pin/hole pair; performing additive manufacture of a workpiece on the workpiece holder using the manufacturing device, the temperature of the support system increasing, producing a clamping effect between the pin and the hole; cooling the support system, whereby the clamping effect is released; disengaging the workpiece holder together with the workpiece produced thereon from the base support; and arranging the workpiece holder on a support of an installation for the subtractive post-processing of the workpiece wherein a positioning element of the support and the positioning device of the workpiece holder engage in each other.

Abstract: A support system includes a base support to be secured in a process chamber of a production system, and includes at least one positioning element. A workpiece holder has upper and lower faces. The workpiece support has at least one first positioning device. The positioning element and the first positioning device form a pin/hole pair. A section of the pin has a first thermal expansion coefficient. A section of the hole controlling positional accuracy has a second thermal expansion coefficient. In a first alternative, the second thermal expansion coefficient is lower than the first, producing a clamping effect between the pin and hole upon temperature increase of the support system. Alternatively, the first thermal expansion coefficient is lower than the second, producing a clamping effect upon temperature increase of the support system. The invention additionally relates to a method for producing a workpiece.
