Abstract: A method for post-treating a three-dimensional object produced by selectively solidifying, layer by layer, of a building material in powder form and/or post-treating unsolidified building material in which the three-dimensional object is embedded. The three-dimensional object and/or the unsolidified building material may be treated with a liquid. The liquid may comprises a liquid carrier substance and at least one further substance that reduces surface tension of the carrier substance.

Abstract: The invention relates to a process and an apparatus for chemical smoothing of a plastic part (10) produced by selective layerwise consolidation of a construction material. The process comprises the steps of: temperature-controlling the plastic part to a first temperature; temperature-controlling solvent vapour (8) comprising a solvent to a second temperature; subjecting the plastic part (10) to the solvent vapour (8) temperature-controlled to the second temperature for a particular duration, wherein the subjecting of the plastic part (10) to the solvent vapour (8) has the result that an outer layer of the plastic part (10) is liquefied; and discharging at least a portion of the solvent vapour (8) after the particular duration, wherein the plastic part (10) is stationary from commencement of the temperature-controlling of the plastic part until termination of the discharging of the solvent vapour (8).

Abstract: Method for manufacturing a three-dimensional object by layer-wise application and selective solidification of a building material with the step of applying a layer of the building material on a building base within a build area and with the step of selectively solidifying the applied layer by solidifying an area of the applied layer which corresponds to the cross-section of the object in the layer in order to produce a solidified area in the layer. The steps of applying and selectively solidifying are repeated until the three-dimensional object is completed. At least once during manufacturing the three-dimensional object, a sub-area that is only a predetermined portion of the solidified area is after-treated. The sub-area is located substantially inside the solidified area.

Abstract: A method for post-treating a three-dimensional object (2) produced by selectively solidifying, layer by layer, of a building material (15) in powder form and/or unsolidified building material (13) in which the three-dimensional object (2) is embedded, wherein the three-dimensional object (2) produced and/or the unsolidified building material (13) are treated with a liquid (33). The liquid (33) comprises a liquid carrier substance and at least one further substance that reduces the surface tension of the carrier substance.

Abstract: The present invention relates to a method and to a device for generatively manufacturing a three-dimensional object (3). A powdery material (11) is applied layerwise onto a support (5) of the device or onto a previously applied layer, and the powdery material (11) is solidified by energetic radiation (8?) at locations corresponding to the object (3). The powdery material (11) is solidified such that a digital, machine readable and three-dimensional coded character is provided at a surface of the object (3).
