Claim 17:
18. 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.
