PCT No. PCT/EP94/04214 Sec. 371 Date Aug. 22, 1995 Sec. 102(e) Date Aug. 22, 1995 PCT Filed Dec. 19, 1994 PCT Pub. No. WO95/18715 PCT Pub. Date Jul. 13, 1995In a method and an apparatus for producing three-dimensional objects by layerwise solidification of a material the problem is encountered that, in particular when using powdery or pasty material, a material layer having an exactly adjusted thickness can not be generated in a sufficiently fast manner. In order to solve this problem, it is proposed to scrape the material by means of a vibrating wiper member (21, 22) when applying the material or to provide a movable container (13) used for applying the material with such wiper members (21, 22) at the lower side thereof.
