Title:
METHOD FOR MANUFACTURING THREE-DIMENSIONAL OBJECT AND MANUFACTURING DEVICE USED THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/054320
Kind Code:
A1
Abstract:
According to the present invention, a stacked body (13) is obtained by repeating multiple times a step for forming a ceramics powder layer made of ceramics powder and a step for applying, to a desired region of said ceramics powder layer, a liquid precursor composition containing at least water and at least one among metal alkoxide, metal chloride, hydrolysate of said metal alkoxide, polycondensate of said hydrolysate; then said stacked body (13) is heated at a lower temperature than the sintering temperature of the ceramics powder; ceramics particles in a region (11') to which the precursor composition is not applied are removed to thereby obtain a three-dimensional object (14).
