三维形状造型物的制造方法及三维形状造型物
摘要：
本发明提供一种良好地应对造型板的弯曲变形的三维形状造型物的制造方法。本发明的三维形状造型物的制造方法的特征在于，重复进行如下工序：（i）对设置在造型板上的粉末层的规定部位照射光束而使所述规定部位的粉末烧结或熔融固化，从而形成固化层；以及（ii）在得到的固化层上形成新的粉末层，对所述新的粉末层的规定部位照射光束，从而形成进一步的固化层；在制造该三维形状造型物之前或制造该三维形状造型物时，（a）对造型板实施热处理而使造型板发生弯曲，（b）对弯曲后的造型板的至少下表面实施平坦加工。
摘要（英）：

Disclosed is a method for producing a three-dimensional shaped article which is suitably dealt with warpage deformation of a shaping plate. Specifically disclosed is a method for producing a three-dimensional shaped article, wherein (i) a step for irradiating a predetermined point of a powder layer provided on a shaping plate with light beams, and sintering, or melting and solidifying the powder at the predetermined point to form a solidified layer, and (ii) a step for forming a new powder layer on the obtained solidified layer, and irradiating a predetermined point of the new powder layer with light beams to form an additional solidified layer are repeatedly performed, and before the production of the three-dimensional shaped article or during the production thereof, (a) heat treatment is applied to the shaping plate to produce warpage on the shaping plate, and (b) at least the lower surface of the warped shaping plate is flattened.
