Title:
THREE-DIMENSIONAL LAMINATION DEVICE AND THREE-DIMENSIONAL LAMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/151864
Kind Code:
A1
Abstract:
Provided are: a three-dimensional lamination device which manufactures three-dimensional objects with high accuracy; and a three-dimensional lamination method. The three-dimensional lamination device, which forms three-dimensional shapes by laminating moulded layers to a base part, has: a powder supply part which supplies a powder material; a light irradiation part which irradiates the powder material with a light beam and forms the moulded layers by sintering or by melting and solidifying at least one portion of the powder material irradiated by the light beam; a heating part which selectively heats the base part, a region of the moulded layers in which the light beam has passed through a position to be irradiated, or a region in which the light beam has yet to pass through the position to be radiated; and a control device which controls the operations of the powder supply part, the light irradiation part, and the heating part.
