    • 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.
    • 一种光学制造方法,其能够通过用光束烧结来调整制造三维制品的每个光学制造区域所需的硬度和密度,并且工作效率优异地执行以下步骤:形成粉末层 预定厚度,然后用光束烧结粉末层,预定次数,切割粉末层的周边,并且通过改变光束烧结单位面积的照射量来改变烧结程度 根据与每个粉末层的外周表面的最短距离的表面。
