1 - 11 . (canceled)
12 . A process for producing a three-dimensional object including the following steps:
applying and flattening a solidifiable liquid or powder material layer on a target surface,
irradiating or spraying a select part of the layer with an energy beam or material, corresponding to a cross section of the object, so that the material layer solidifies in this selected part, wherein the irradiated or sprayed part warms its environment,
repeating the steps of application and radiation for a plurality of layers, which form a layer cake, such that the solidified parts of adjacent layers join to form an object, wherein a tempering occurs within the layer cake.
13 . The process according to claim 12 , wherein the tempering occurs in multiple positions in at least one plane of the construction space.
14 . The process according to claim 12 , wherein the tempering occurs in multiple variable positions in at least one plane of the construction space.
15 . The process according to claim 12 , wherein the tempering occurs differentially at different positions within the construction space.
16 . The process according to claim 12 , wherein the control or regulation of the tempering occurs differentially within the construction space.
17 . The process according to claim 12 , wherein the control or regulation of the tempering occurs differentially at different positions within the construction space.
18 . A device for producing a three-dimensional object from a solidifiable liquid or powder material, said device including:
a device for applying a layer of the material upon a target surface in a construction space,
a device for flattening the material layer,
a device for radiating or spraying a select part of the material layer with an energy or material beam,
a device for lowering the target surface within the construction space, and
at least one tempering device, which is provided within the construction space.
19 . The device according to claim 18 , wherein the at least one tempering device is provided locationally fixed in the construction space.
20 . The device according to claim 18 , wherein the construction floor is designed for receiving of at least one tempering device.
21 . The device according to claim 18 , wherein the construction floor is designed for the variable receiving of at least one tempering device.
22 . The device according to claim 18 , wherein the receptacle is in the form of a two-dimensional receptacle matrix.
23 . The device according to claim 18 , wherein the at least one tempering device includes independently or differentially temperable sectors.
24 . The device according to claim 18 , wherein the device includes at least one control or regulating device for separate control or regulation of various tempering devices.
25 . The device according to claim 18 , wherein the device includes at least one control or regulating device for separate control or regulating of different sectors of at least one tempering device.
