三次元造形装置
Document Type and Number:
Japanese Patent JP6505517
Kind Code:
B2
Abstract:
A three-dimensional printing apparatus includes a controller to control first and second projectors that apply equal or substantially equal total amounts of optical energy. The controller performs first and second projecting operations. The first projecting operation involves simultaneously projecting first and second cross-sectional sub-images from the first projector onto first and second areas of an image projecting surface, respectively, and the second and third cross-sectional sub-images from the second projector onto the second and third areas of the image projecting surface, respectively. The second projecting operation involves simultaneously projecting the first cross-sectional sub-image from the first projector onto the first area and the third cross-sectional sub-image from the second projector onto the third area. The controller equalizes the number of times the first to third cross-sectional sub-images are to be respectively projected onto the first to third areas.
