Title:
POWDERY MATERIAL, METHOD FOR PRODUCING THREE-DIMENSIONALLY SHAPED PRODUCT, AND THREE-DIMENSIONALLY SHAPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/104234
Kind Code:
A1
Abstract:
The present invention pertains to a powdery material to be used for producing a three-dimensionally shaped product by: selectively applying laser light onto a thin layer of the powdery material including a plurality of particles; forming shaped-product layers by the plurality of particles being sintered or melted and bonded together; and layering the shaped-product layers. The plurality of particles include coating particles that have: first metallic particles; and second metallic particles forming one or more layers and coating the surfaces of the first metallic particles in the form of islands, wherein the average particle diameter of the first metallic particles is 1.2 or more times the average particle diameter of the second metallic particles. According to the powdery material, regardless of a material of the metallic particles, the metallic particles included in the powdery material can be easily sintered or melted and bonded together through application of laser light, and a three-dimensionally shaped product can be produced at low cost.
