Abstract
A high-precision three-dimensional laminated and shaped object is shaped based on a captured image. A three-dimensional laminating and shaping apparatus includes a material ejector that ejects a material of a three-dimensional laminated and shaped object onto a shaping table, a light beam irradiator that irradiates the ejected material with a light beam, an image capturer that captures a molten pool formed by irradiating the ejected material with the light beam, a scanning direction determiner that determines a scanning direction of the light beam with respect to a shaped object based on a change in a position of the shaping table, a detector that detects the molten pool based on an image captured by the image capturer and the scanning direction, and a shaping controller that controls at least one of an output of the light beam and a scanning speed of the light beam based on the detected molten pool.
