Apparatus and method for the manufacture of a three-dimensional object

A method for the manufacture of a three-dimensional object, comprising the steps of:

• (a) applying a layer of a building material to be solidified through electromagnetic or particle radiation, onto a base or a layer solidified before;
• (b) solidifying the layer of the building material that was applied in step (a) by exposure to electromagnetic or particle radiation at the positions in the layer that are corresponding to the cross-section of the object;
• (c) repeating the steps (a) and (b) until the three-dimensional object has been completed,
• wherein the temperature of the building material is measured in a measurement region, which is a partial region of the applied layer by means of a temperature measuring assembly in a non-contact manner, wherein the position of the measurement region is adjusted or altered by means of a position adjustment device independently of any alteration of the position of the region upon which the electromagnetic or particle radiation acts in step (b), wherein the position adjustment device comprises a swivelling device for changing the angular position of the temperature measuring assembly in relation to the layer of the building material,
• wherein the position of the measurement region is adjusted or altered by means of the position adjustment device such that the measurement region does not overlap with a region in the layer that is being simultaneously solidified.
