Abstract
The present invention provides a powder for layer manufacturing including non-hydratable matrix particles, and water-soluble adhesive particles. The powder for layer manufacturing includes, as the water-soluble adhesive particles, polyvinyl alcohol resin particles with a saponification degree of 86.5 mol % to 89.0 mol %, an average degree of polymerization of 400 to 600, a viscosity of a 4 mass % aqueous solution at 20° C. of 4.6 mPa to 5.4 mPa, and an average particle diameter of 20 μm to 60 μm.
