PCT No. PCT/EP93/03725 Sec. 371 Date Aug. 8, 1994 Sec. 102(e) Date Aug. 8, 1994 PCT Filed Dec. 30, 1993 PCT Pub. No. WO94/13771 PCT Pub. Date Jul. 21, 1994In a method for producing a three-dimensional object wherein the object is produced layer by layer by applying a layer of a material which can be solidified by irradiation with electromagnetic radiation and subsequently solidifying the layer at the points corresponding to the object by irradiation the problem is encountered that the production process is considerably delayed by long heating and cooldown times within the apparatus used for the production. According to the invention this problem is solved by irradiating and thereby solidifying in each layer a region of the material surrounding the object so as to produce a container wall (26) for the material (21).
