Additive manufacturing method and resin-coated sand for additive manufacturing

摘要

Lamination molding resin-coated sand which can advantageously enhance accuracy for a formed article, is lamination molding resin-coated sand used for lamination molding for forming an article by laminating sand layers (50) in thickness direction. Sand particles (53) coated with resin (54) are 20 to 100 mu m in diameter and generally spherical. The resin (54) has a mean molecular weight of about 2000 to 10000 and a fusion temperature of 100 DEG C or higher. IMAGE
