Claim 10:
11. A device for the lithograph-based additive production of three-dimensional shaped bodies for carrying out a method according to claim 1, comprising a first radiation source of electromagnetic radiation and a material support that, at least in a region thereof, is permeable for the radiation of the first radiation source and that is provided for supporting a material solidifiable by the action of the radiation, further comprising a building platform, which is held at an adjustable distance from the material support, a first irradiation unit that comprises the first radiation source and that is controllable for the location-selective irradiation of the material located between the building platform and the material support through the material support, and a heating device for heating the material located between the building platform and the material support, wherein the heating device comprises a second irradiation unit with a second radiation source of electromagnetic radiation directed to the material support, the radiation from the second radiation source being absorbed by the material support sufficiently to heat the material support to a temperature of 40-300° C., and wherein the electromagnetic radiation of the second radiation source is directed to the region of the material support that is transparent to the radiation of the first radiation source, and wherein the electromagnetic radiation of the second radiation source thereby causes the material support and the material on the material support to be heated uniformly.
