Kind Code:
A
Abstract:
To provide a manufacturing method of an article capable of suppressing deformation of an article when firing a cured product fabricated by 3D lamination molding method.SOLUTION: A form model having an objective profile is fabricated by using a slurry photocuring type lamination molding method. Concretely, by fabricating a lower support part 25 which supports an extended part 43 by contacting with a base 41 side surface of the extended part 43 and a base 41 surface, a composite cured product 27 which is an integrated body of a cured product 23 and the lower support part 25 is fabricated. Then, the composite cured product 27 is parted from the base 41, followed by firing the composite cured product 27, to fabricate a composite article 53. Subsequently, the lower support part (i.e., a lower article 55) after the firing is parted from the composite article 53 to fabricate an article 1.SELECTED DRAWING: Figure 1
