<P>PROBLEM TO BE SOLVED: To precisely manufacture a three-dimensional structure such as a dental material. <P>SOLUTION: A hopper 20 which scatters a powder from nozzles 22, a scraping plate 21 which regulates the scattered powder to be in a prescribed thickness, a mechanism 26 which discharges a liquid onto a layer of the accumulated powder, and light sources 28 which solidify the liquid received and contained in the layer of the accumulated powder, are disposed sequentially above a circular shaping stage 16 which moves downward at a prescribed pitch, while it rotates. The position and the amount of discharge of the liquid in the discharging mechanism 26 are controlled by control signals obtained by a computer, corresponding to the desired three-dimensional structure. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
