A three-dimensional object manufacturing apparatus that may be equipped to efficiently separate a three-dimensional object from a mounting unit is provided. The printing apparatus includes: a mounting unit having a mounting surface on which a three-dimensional object being manufactured is mounted; a separator to separate the three-dimensional object from the mounting unit; a moving unit to move the three-dimensional object remaining on the mounting surface and the separator unit relative to each other after the manufacturing of the three-dimensional object is completed, the three-dimensional object on the mounting surface and the separator being moved to arrive at a separating position at which the three-dimensional object is separated by the separator; and a controller that controls the moving unit.
