Kind Code:
A1
Abstract:
One embodiment of the present invention relates to a method for manufacturing a three-dimensional molded object, the method comprising: (i) a step for irradiating specific positions on a powder layer with light beams to sinter or melt/solidify powder at the specific positions, thereby forming a solidification layer; and (ii) a step for forming a new powder layer on the obtained solidification layer, and irradiating specific positions on the new powder layer with light beams, thereby additionally forming a solidification layer, wherein the above steps are repeated to alternately stack the powder layer and the solidification layer to manufacture a three-dimensional molded object. In particular, according to the one embodiment of the present invention, the solidification layer is formed from a plurality of overlapping solidification parts, and after a first solidification part is formed as the solidification part that is formed first, at least both circumferential edge sections of the first solidification part are irradiated with light beams.
