LAMINATION MOLDING APPARATUS

摘要

A lamination molding apparatus 10 includes a powder layer forming apparatus 20, a recoating head 30, a servo motor 16, a laser irradiating device 40, a numerical control apparatus 52, a laser control apparatus 54 and a computer aided manufacturing (CAM) system 56. The blade 31 moves in the horizontal axis direction so as to form the powder layer on a predetermined molding region. The laser control apparatus 54 controls the laser irradiating device 40 and calculates an irradiation range of a laser beam for every powder layer. The numerical control apparatus 52 obtains data of the irradiation range from the laser irradiating device 40 and outputs a move command such that the blade 31 moves at a feed speed faster than a pre-set feed speed adapted for recoating, in the molding region outside of the irradiation range.

主权项

1. A lamination molding apparatus, comprising:
a blade, forming a powder layer at a predetermined molding region by moving in a horizontal axis direction for each sliced layer sliced from an entire molding space with a predetermined thickness, wherein the entire molding space includes a desired molding object; a laser irradiating device irradiating a laser beam at a predetermined irradiation region in the molding region; a laser control apparatus controlling the laser irradiating device and calculating an irradiation range of the laser beam in the horizontal axis direction for the each sliced layers; and a numerical control apparatus obtaining data of the irradiation range from the laser control apparatus and outputting a move command, so as to move the blade at a feed speed faster than a preset feed speed adapted for recoating, at a molding range outside the irradiation range.
