PROCESS FOR PRODUCING THREE-DIMENSIONALLY SHAPED OBJECT AND DEVICE FOR PRODUCING SAME |
摘要 |
There is provided a method for manufacturing a
three-dimensional shaped object. The method of the present invention comprises the steps of: (i) forming a solidified layer by irradiating a predetermined portion of a powder layer with a light beam, thereby allowing sintering of the powder of the predetermined portion or melting and subsequent solidification thereof; and (ii) forming another solidified layer by newly forming a powder layer on the resulting solidified layer, and
then irradiating another predetermined portion of the new powder layer with the light beam, the steps (i) and (ii) being repeatedly performed in a chamber; wherein a localized gas flow is provided in the chamber, and at least a part of a fume generated by the irradiation of the light beam is entrained by the localized gas flow. |
