Abstract: Described herein are a method for manufacturing a three-dimensional object and a method for preparing data for a nozzle movement path(s) used in the same, and an apparatus for manufacturing the three-dimensional object and a computer for preparing data for nozzle movement paths used in the same. By repeating the step of forming an outer shell material portion constituting part of an outer shell of a three-dimensional object by ejecting a hard shaping material from a nozzle onto a stage, and the step of forming an inner core material portion constituting part of an inner core of the three-dimensional object by ejecting a soft shaping material from a nozzle to an inner region surrounded by the outer shell material portion, the three-dimensional object including the outer shell and the inner core respectively formed from the outer shell material portion and the inner core material portion in plural layers is formed.

Abstract: A method for producing a three-dimensional (3D) object having excellent moldability and mechanical characteristics is provided. The method includes a molding step of irradiating a composition filled in the cavity of a mold with electromagnetic waves having a wavelength of from 0.01 m to 100 m, and molding the composition into the 3D object. The composition for molding a 3D object contains a solvent and at least one of a polymer and a polymerizable monomer.
