PROBLEM TO BE SOLVED: To provide a contact apparatus for use in an apparatus for producing three-dimensional workpieces capable of producing more workpieces by a particularly efficient method.SOLUTION: A contact apparatus 44 comprises a replaceable building chamber 20 adapted to receive a workpiece and a building chamber support element 38. A first contact element 46 is fastened to the replaceable building chamber 20, comprises a first electrical conductor element 48, and is provided with a first planar conductor surface 50. A second contact element 52 is fastened to the building chamber support element 38 and comprises a second electrical conductor element 54, the second electrical conductor element 54 being provided with a second planar conductor surface 56. The first planar conductor surface 50 and the second planar conductor surface 56 are adapted to interact with each other so as to establish an electrical contact between the replaceable building chamber 20 and the building chamber support element 38 when the replaceable building chamber 20 is supported on the building chamber support element 38.SELECTED DRAWING: Figure 2 |
