THREE-DIMENSIONAL OBJECT BUILDING APPARATUS AND METHOD FOR BUILDING THREE-DIMENSIONAL OBJECT

摘要

The three-dimensional object building apparatus includes a powder delivering unit that delivers a powder on an object building area, a powder flattening device that flattens the powder delivered from the powder delivering unit to form a powder layer, and a light beam radiating unit that is disposed above the object building area and radiates a light beam on the powder layer to sinter or melt solidify the powder for building an object. The three-dimensional object building apparatus also includes a transferring mechanism that moves the light beam radiating unit in three-dimensional directions, and a shroud that moves integrally with the light beam radiating unit and surrounds a space above an area of the powder layer that is smaller than the object building area around a radiation of the light beam. The powder delivering unit and the powder flattening device move integrally with the light beam radiating unit.

1. A three-dimensional object building apparatus, comprising:
a powder delivering unit that delivers a powder on an object building area; a powder flattening device that flattens the powder delivered from the powder delivering unit to form a powder layer; a light beam radiating unit that is disposed above the object building area and radiates a light beam on the powder layer to sinter or melt solidify the powder for building an object; a transferring mechanism that moves the light beam radiating unit in three-dimensional directions; a cover that moves integrally with the light beam radiating unit and surrounds a space above an area of the powder layer that is smaller than the object building area around a radiation of the light beam; and wherein the powder delivering unit and the powder flattening device move integrally with the light beam radiating unit.
