Manufacturing method for three-dimensional object

Abstract

To more efficiently manufacture a three-dimensional object shaped by layering a shaping material with a three-dimensional printer. A manufacturing method for a three-dimensional object according to an embodiment includes: a first shaping process (step S12) of layering a shaping material with a three-dimensional object shaping device (three-dimensional printer) to shape a first shaping portion including a recess opened in a layering direction of the shaping material; a closing process (step S15) of closing an open end of the recess of the first shaping portion; and a second shaping process (step S16) of layering the shaping material with the three-dimensional object shaping device (three-dimensional printer) on the first shaping portion, which open end of the recess is closed, to shape a second shaping portion.
