Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A powder for layer manufacturing, comprising: non-hydratable matrix particles; and water-soluble adhesive particles, the powder for layer manufacturing including, 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. 2. The powder for layer manufacturing according to claim 1 , wherein the average particle diameter of the non-hydratable matrix particles is 1 μm to 50 μm. 3. The powder for layer manufacturing according to claim 1 , wherein, when the total mass of the powder for layer manufacturing is 100 parts by mass, the content of the water-soluble adhesive particles is 1 part by mass to 20 parts by mass. 4. The powder for layer manufacturing according to claim 1 , wherein the non-hydratable matrix particles are constituted mainly by a metal including at least one element selected from the group consisting of Al, Zr, Ti, Zn, Ni, and Fe or an alloy thereof. 5. The powder for layer manufacturing according to claim 1 , wherein the non-hydratable matrix particles are constituted mainly by an oxide including at least one element selected from the group consisting of Al, Zr, Ti, Zn, Ni, Fe, and Si. 6. A layered shaped article comprising a solidified product of the powder for layer manufacturing according to claim 1 .
