Abstract
A method of manufacturing a 3D modeled object, includes modeling including applying a modeling solution to powder laid in layers, hardening the powder to which the modeling solution applied to form modeling layers, and sequentially stacking the modeling layers to form a 3D modeled object; and immersing the 3D modeled object modeled at the modeling in a removal solution to remove the powder to which the modeling solution is not applied. At the modeling, the modeling solution is applied such that a density of the modeling solution in an inside of the 3D modeled object is smaller than a density of the modeling solution in a surface of the 3D modeled object and an area of the powder to which the modeling solution is applied and an area of the powder to which the modeling solution is not applied are alternate in the inside of the 3D modeled object.
