Preparation and three-dimensionally shaped object obtained therefrom of a three-dimensional shaped object

The invention, and processes, to form a solidified layer by irradiated powder sintered or melted and solidified to the predetermined portion of the light beam to a predetermined portion of the powder layer formed on (i) shaping plates, (ii) resulting form a new powder layer on the solidified layer, manufacture of the new powder layer three-dimensionally shaped object to repeat a step of forming a further solidified layer by irradiating a light beam to a predetermined portion of a method, formed to consist of a low-density region of the solidified layer solidified density 95% to 100% of the high-density regions and solidified density of 0% to 95% (not including 95%), high-density area is three-dimensional manufacturing process which is a region where force is exerted when using the shaped object.
