Abstract

An apparatus for producing a three-dimensional work piece comprises a carrier to receive a layer of raw material powder, a control unit, an irradiation system adapted to selectively irradiate electromagnetic or particle radiation onto the layer of raw material powder applied onto the carrier, wherein the control unit controls the operation of the irradiation system in such a manner that the raw material powder is heated to a first temperature which allows sintering and/or melting of the raw material powder in order to generate a layer of the three-dimensional work piece, and a heating system adapted to selectively irradiate electromagnetic or particle radiation onto the layer of raw material powder applied onto the carrier, wherein the control unit is adapted to control the operation of the heating system in such a manner that the raw material powder is heated to a second temperature that is lower than the first temperature.
