Document Type and Number:
WIPO Patent Application WO/2017/154457
Kind Code:
A1
Abstract:
Shaping accuracy of a shaped article is improved. A three-dimensional shaping apparatus 100 is provided with: a light source 251; a container 201 that stores photo-curing resin material RA; an image forming element 253; a projection optical system 255; a holding plate 202 that moves a shaped layer cured by image light at a shaping position in a Z1 direction separating from a light transmission member 212; and a control unit 300 that controls the image forming element 253. The image forming element 253 has a plurality of pixels capable of separately adjusting light output to the projection optical system 255. An image forming position of the light passing through the projection optical system 255 is set to be deviated in Z1 and Z2 directions with respect to the shaping position. The control unit 300 divides image data into divided regions corresponding to the respective pixels of the image forming elements 253. The control unit 300 controls the light output from pixels corresponding to divided regions including pixel data indicating a shaping part and pixel data indicating a non-shaping part among the plurality of pixels to a halftone.
