PCT No. PCT/EP93/02709 Sec. 371 Date May 25, 1994 Sec. 102(e) Date May 25, 1994 PCT Filed Oct. 4, 1993 PCT Pub. No. WO94/07681 PCT Pub. Date Apr. 14, 1994.In a method for producing a three-dimensional object by successive solidification of superposed layers of the object a deformation of the object caused by shrinkage during the solidification shall be reduced. To this end first of all respective partial regions (6a . . . 6k) of a layer are solidified and simultaneously connected with underlying partial regions of the previously solidified layer to form multilayered cells and thereafter adjacent partial regions of the same layer are interconnected by solidifying narrow connecting regions (8a . . . 8p). The intermediate regions (7) between the individual partial regions are solidified by post-curing.
