THREE-DIMENSIONAL SHAPING DEVICE

摘要

A three-dimensional shaping device and a three-dimensional shaping method are described. In the three-dimensional shaping device, a region of an elevatable/lowerable table for forming a powder layer and a vicinity thereof and a region of a powder supply device and a vicinity thereof are divided by a shield plate, an inert gas injection port is provided in the former region, the shield plate is made so as to be freely opened or closed so that a powder spraying squeegee traveling on the table is passed through, or a pipe which supplies powder from the powder supply device to the powder spraying squeegee which has traveled to the side of the shield plate penetrates through the shield plate, and a sintering device is provided which applies a laser beam via a transparent region in a ceiling of a chamber.
