三次元形状造形物の製造方法および金型
Document Type and Number:
Japanese Patent JP3557926
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To manufacture hollow parts, parts which are different in materials or characteristics corresponding to places, and parts with high air-tightness and high water-tightness in a method for manufacturing a three-dimensional shape by laminating powder hardening layers being scanned with light beams. SOLUTION: In this method, a light beam 30 is radiated on an inorganic or organic powder material 20 to form a hardening layer 22, and the hardening layers 22 are piled up to manufacture a desired three dimensional shaped part M. During a process for manufacturing the parts, one part of the powder material 20 not being hardened is removed, a submerging member 40 manufactured at another is submerged in the removed portion 26. Thereafter, the light beam 30 is radiated on the powder material 20 so as to pile up the hardening layers 22.
