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.
Claims19
A method for post-treating unsolidified building material, comprising:
- producing a three-dimensional object by selectively solidifying, layer by layer, a building material in powder form such that the three-dimensional object is embedded in the unsolidified building material;
- treating the unsolidified building material with a liquid;
- and
- drying the unsolidified building material after the unsolidified building material has been treated with the liquid,
- wherein the liquid comprises a liquid carrier substance and at least one further substance that reduces surface tension of the carrier substance;
- and
- wherein the carrier substance and the at least one further substance are matched to one another such that, after drying the unsolidified building material, no residues remain on the unsolidified building material, which residues lead to an incompatible material combination and/or contamination with regard to further use.
A method for post-treating unsolidified building material, comprising:
- producing a first three-dimensional object by selectively solidifying, layer by layer, a building material in powder form such that the first three-dimensional object is embedded in the unsolidified building material;
- selecting a liquid that includes a liquid carrier substance and at least one further substance that reduces a surface tension of the carrier substance, the selecting being performed so as to reduce a surface tension of the liquid on the unsolidified building material when the unsolidified building material is cooled with the liquid;
- cooling the unsolidified building material with the liquid;
- drying the unsolidified building material after the unsolidified building material has been cooled with the liquid so as to produce a treated unsolidified building material;
- and
- producing a second three-dimensional object by selectively solidifying, layer by layer, the treated unsolidified building material.
