Abstract
Method for cooling a three-dimensional object manufactured by layer-wise selective solidification of a pulverulent building material and non-solidified building material in which the three-dimensional object is embedded by a treatment with a fluid medium. The fluid medium is constituted by a carrier gas that is specifically enriched with an additional component which comprises a further gas and/or a liquid and/or by a gas mixture from which specifically at least one mixture components is at least partially withdrawn.
Claims19
A method for cooling a three-dimensional object manufactured by layer-wise selective solidification of a pulverulent building material and non-solidified building material in which the three-dimensional object is embedded, comprising:
- providing a cooling container that contains the three-dimensional object and the non-solidified building material in which the three-dimensional object is embedded, the cooling container having a portion permeable for a fluid medium;
- preparing the fluid medium in a preparation unit, comprising:
- providing a carrier gas and specifically enriching the carrier gas with an additional component comprising a further gas and/or a liquid;
- and/or
- providing a gas mixture and adjusting the composition of the gas mixture in a predetermined manner by partial or complete withdrawal of one or more mixture components;
- passing the fluid medium through the portion permeable for the fluid medium into the cooling container and through the non-solidified building material in which the three-dimensional object is embedded;
- conducting the fluid medium in a circular flow back to the preparation unit and enriching the carrier gas with the additional component and/or adjusting the composition of the gas mixture in the predetermined manner;
- and
- again passing the fluid medium from the preparation unit through the portion permeable for the fluid medium into the cooling container and through the non-solidified building material in which the three-dimensional object is embedded.
A method of cooling a three-dimensional object manufactured by layer-wise selective solidification of a building material and further cooling non-solidified building material in which the three-dimensional object is embedded, the method comprising:
- providing a fluid medium including a carrier gas enriched with an additional component comprising a further gas and/or a liquid;
- introducing the fluid medium into a cooling container that includes the non-solidified building material and the three-dimensional object through a portion of the cooling container permeable for the fluid medium;
- circulating the fluid medium to cause further enrichment of the fluid medium by the additional component in an area separate from the cooling container;
- and
- re-introducing the fluid medium through the portion of the cooling container permeable for the fluid medium and into the cooling container.
