METHOD FOR PRODUCING CALCIUM PHOSPHATE MOLDED ARTICLE, CALCIUM PHOSPHATE MOLDED ARTICLE, AND MATERIAL FOR TRANSPLANTATION
Provided are a method for rapidly producing a calcium phosphate molded article having high strength with high shaping precision, a calcium phosphate molded article produced by the method, and a material for transplantation. Disclosed is a method for producing a calcium phosphate molded article, the method including: step (a) of forming a layer containing a calcium phosphate powder having a ratio of the numbers of atoms of Ca/P of 1.4 to 1.8 on a substrate; and step (b) of producing a calcium phosphate molded article by jetting an organic acid solution having a pH of 3.5 or lower and including an organic acid whose calcium salt has a solubility in water of 1 g/100 mL or less, through a nozzle unit into a liquid droplet state, thereby dropping the organic acid solution onto the layer containing a calcium phosphate powder formed in step (a).
