Title:
三次元造形物の製造方法
Document Type and Number:
Japanese Patent JP6977537
Kind Code:
B2
Abstract:
A production method of a three-dimensionally shaped object, includes a first layer forming step of forming a first layer by using a first composition containing first powder and binder, a second layer forming step of forming a second layer by using a second composition containing second powder, third powder, and binder, and a sintering step of sintering the first powder and the second powder. In a case where the first powder and the second powder are of the same material, difference in a contraction rate between the first layer and the second layer in the sintering step is reduced by matching a filling rate of the first powder in the first composition with a total filling rate of the second powder and the third powder in the second composition and matching an average particle diameter of the first powder with an average particle diameter of the second powder.
