Document Type and Number:
WIPO Patent Application WO/2017/209136
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for quickly producing a high-strength calcium phosphate molded article with high shaping accuracy, a calcium phosphate molded article produced by the method, and a material for transplantation. The present invention provides a method for producing a calcium phosphate molded article, the method comprising step a for forming, on a substrate, a layer containing a calcium phosphate powder having an atomicity ratio of Ca/P of 1.4-1.8; and step b for discharging an organic acid solution in which the solubility of a calcium salt of an organic acid is 1 g/100 mL or less in water, and which has a pH of 3.5 or lower, in the form of droplets, from a nozzle part, and thereby dropping the organic acid solution onto the layer that contains the calcium phosphate powder and is formed in step a, to produce the calcium phosphate molded article.
