1. An apparatus for the manufacture of a three-dimensional object by solidifying layers of a building material at the positions corresponding to the respective cross-section of the object, by the action of electromagnetic or particle radiation, the apparatus comprising:

  • a temperature measuring assembly for non-contact measurement of the temperature of the building material in a measurement region, which is a partial region of a layer of the building material, wherein the apparatus further comprises a position adjustment device for changing a position of the measurement region of the temperature measuring assembly independently of an alteration of the position of the region upon which said electromagnetic or particle radiation is acting,wherein the position adjustment device comprises a swivelling device for changing an angular position of the temperature measuring assembly in relation to the layer of the building material, and the apparatus further comprises a control device, wherein the control device is configured to control the swivelling device such that the angular position of the temperature measuring assembly is modified individually for each layer.
