PURPOSE: To produce a three-dimensional object by forming a solid crosssection of an object on a surface of liquid by using a movable spot beam of a programmed UV light and forming successive adjacent cross-sectional laminae. CONSTITUTION: A container 21 is filled with a UV curable liquid 22 or the like to provide a working surface 23. A programmable source of ultraviolet light 26 or the like produces a spot of ultraviolet light 27 in the surface 23. The position of a movable elevator platform 29 is controlled by a computer 28, and a three-dimensional object 30 is produced by step-wise build-up of integrated laminae such as 30a, 30b, 30c. A portion of new liquid is converted to a solid material by the programmed UV light spot 27, and adhesively connected to the material below it. |
