Method for manufacturing three-dimensionally shaped object and three-dimensionally shaped object

A method for manufacturing a three-dimensional shaped object, the method comprising the repeated steps of:

• (i) forming a solidified layer by irradiating a predetermined portion of a powder layer with a light beam, thereby allowing a sintering of the powder in the predetermined portion or a melting and subsequent solidification thereof;
• and
• (ii) forming another solidified layer by newly forming a powder layer on the resulting solidified layer, followed by the irradiation of a predetermined portion of the powder layer with the light beam,
• wherein a heater element is disposed on the solidified layer during the repeated steps (i) and (ii), and thereby the heater element is situated within the three-dimensional shaped object,
• wherein the forming of the powder layer and the solidified layer in the steps (i) and (ii) is performed on a supporting part for shaped object;
• and
• a coil heater is used as the heater element, and the coil heater is disposed on the solidified layer via an opening of the supporting part.
