(3) from an object representation specifying a first object surface to be spaced from a second surface by a spacing, and at least partially opposing the second surface, comprising: (4) at least one computer programmed to form a support representation (5) specifying a removable support

(6) to be formed in said spacing out of a material substantially layer by layer, (7) said support in cross sectional width being thin, and comprising a solid which extends along a path connecting said first and second surfaces, the path having a vertical path component which is greater than any horizontal path component; and (8) means for receiving said support representation, and for forming said three-dimensional object out of said medium substantially layer by layer and also for forming said support out of said material substantially layer by layer, in accordance with said object and support representations.
