20150051330 | 3D PRINTING POWDER - The present invention discloses a 3D printing powder produced by laying a gypsum powder; coating a water-soluble resin powder on the gypsum powder, and the water-soluble resin powder forming a colloid in water; pressing the water-soluble resin powder and the gypsum powder flatly to form a mixed layer; and adding water to the mixed layer. The mixed layer formed by using a water-soluble resin powder such as oxazoline resin, polyoxyethylene, or polyvinyl alcohol and pressing the water-soluble resin powder with the gypsum powder, so that the structural strength of 3D printing finished goods can be improved for several times, and the finished goods will not be deformed by external forces or smudged by colorants easily, and the finished goods can have smooth surfaces. | 02-19-2015 |
