PURPOSE:To make it possible to speedily manufacture the title stereo-resin model with high accuracy and low deformation by sharing the scanning for respective division regions of the surface of a light hardening resin or for in dependent slice sectional portions of a stereo-model with each laser beam of each scanner. CONSTITUTION:A three-dimensional CAD is formed with a contour-like sectional data of the sliced layers of thin sectional bodies of designed model. It is prepared on a computer of a controller 15. Next, a work table 12 is held near the surface of a resin liquid 11 to be slightly covered therewith. A laser supply 1 emits four laser beams 8 to scan the surface of the resin liquid 11 through light shutter 4 and light scanner 7, thereby hardening the resin liquid 11. In this case, the laser beams 8 are shared into respective division regions A, B, C and D for sharing the scanning in respective regions. The parallel scans for respective division regions increase the light hardening speed. Further, by oscillating the laser beam in the range of allowable emitting angle, it is possible to harden the sectional portion of the resin with high accuracy. |
