PRODUCTION OF THREE-DIMENSIONAL SHAPED ARTICLE

摘要

PROBLEM TO BE SOLVED: To properly and efficiently perform the planning of a support member and to make the mark generated on the side of a shaped article when the support member is cut off from the formed shaped article inconspicuous in a method connecting the support member, which connects a fixed structural member supporting the part required to be supported of the shaped article, to the part required to be supported of the shaped article when a photo-set layer is formed by irradiating a photo-setting resin with light and a plurality of the photo-set layers are stacked to produce the shaped article having a desired three-dimensional shape. SOLUTION: It is judged whether support is necessary for the respective photo-set layers 40 of a shaped article and the connection part 51c of a support member is formed in the same way as the shaped article so as to be connected to the photo-set layer 40d requiring support in a part of the region not overlapped with the planar shape of the photo-set layer 40c of a lower layer within the planar countour line region of the photo-set layer 40d requiring support or the whole region.
