Abstract
Official abstract text for this publication.
A lamination molding apparatus is provided capable of preventing damage to a cutting device. Every time a sintered body including a sintered layer group consisting of a predetermined number of sintered layers is formed, gas is injected from a gas injector toward a vicinity of a side surface of the newly formed sintered body so as to blow off material powder, and then the side surface of the sintered body is shaved by a cutting tool of the cutting device, wherein the gas injector blows off the material powder by only intermittent injection which repeats short-time gas injection or by a combination of the intermittent injection and continuous injection which continuously injects the gas.
First claim
Opening claim text (preview).
What is claimed is: 1 . A lamination molding apparatus comprising a table, on which a powder layer comprising metal material powder is formed; a laser irradiation device, irradiating a predetermined region of the powder layer formed on the table with a laser beam so as to sinter the predetermined region of the powder layer to form a sintered layer; a cutting device, having a cutting tool that cuts the sintered layer formed by the laser irradiation device; and a gas injector, blowing off the material powder by gas injection, wherein every time a sintered body comprising a sintered layer group consisting of a predetermined number of sintered layers is formed, gas is injected from the gas injector toward a vicinity of a side surface of the newly formed sintered body so as to blow off the material powder, and then the side surface of the sintered body is shaved by the cutting tool, wherein the gas injector blows off the material powder by only intermittent injection which repeats short-time gas injection or by a combination of the intermittent injection and continuous injection which continuously injects the gas. 2 . The lamination molding apparatus according to claim 1 , wherein the gas injector blows off by gas injection the material powder at least to a depth allowing the cutting tool to enter. 3 . The lamination molding apparatus according to claim 1 , wherein a strength of the gas injection performed by the gas injector is in a range of not blowing up the material powder. 4 . The lamination molding apparatus according to claim 1 , wherein a gas injection port of the gas injector has a circular shape, and the gas injected from the gas injection port is blown vertically.
