ABSTRACT:
An optical fabrication method which is capable of adjusting a hardness and a density needed for each optical fabrication area in fabricating a three-dimensional fabricated article through sintering with a light beam, and is excellent in a working efficiency performs the steps of forming a powder layer of a predetermined thickness and then sintering the powder layer with a light beam, a predetermined number of times, cutting a periphery of the powder layers, and changing a degree of sintering by changing an amount of irradiation per unit area of a light-beam sintered surface according to a shortest distance from a peripheral surface of each powder layer.
