POWDERY MATERIAL TO BE SINTERED BY LASER, MANUFACTURING METHOD THEREFOR, THREE-DIMENSIONAL STRUCTURE AND MANUFACTURING METHOD THEREFOR

摘要

PPROBLEM TO BE SOLVED: To secure the hardness of a formed three-dimensional structure, and to secure the melting property of a powder when it is sintered by a laser. PSOLUTION: The powdery material is directed at forming a hardened layer by being sintered through irradiation with a laser beam and forming the three-dimensional structure when the hardened layer is stacked; and consists of many particles each of which has one or more layers of one or more types of different metals coated around a metallic particle. The particle has, for instance, a low-melting metal coated on the outside of the particle of a high-melting metal. PCOPYRIGHT: (C)2006,JPO&NCIPI
