Three-dimensional objects are produced by the polymerization of a photopolymerizable liquid medium with the aid of high-energy radiation by continuously introducing the liquid medium in lamina form from a casting means onto the surface of a carrier liquid which has a higher specific gravity than the photopolymerizable medium and is not miscible therewith. This lamina is polymerized by irradiation to form a laminar, two-dimensional polymer layer, then the surface of the carrier liquid is raised and another lamina of the photopolymerizable medium is introduced onto the surface and polymerized to form a further polymer layer which combines with the preceding one. These steps are repeated until the three-dimensional object is formed. The steps of forming the polymer lamina and raising the surface of the carrier liquid may be computer controlled.
