RESIN POWDER FOR STEREOSCOPIC SHAPING, STEREOSCOPIC SHAPING APPARATUS, PRODUCTION METHOD FOR STEREOSCOPIC SHAPING ARTICLE, AND RESIN POWDER

摘要

To solve a problem of causing a surface defect called orange peel such as a rough surface, a pore or distortion in a shaped article by shaping using a recycled resin powder for stereoscopic shaping, or decreasing tensile strength of the shaped article.SOLUTION: There is provided resin powder for stereoscopic shaping, comprising: a melting point of 100°C or higher by measuring in accordance with ISO 3146; and a ratio of greater than 0.80 and less than 1.20 in dividing of a melt mass flow rate after keeping a temperature by a melt mass flow rate before keeping the temperature, when the melt mass flow rates before and after keeping at a temperature of 15°C lower than a melting point at a pressure of 0.1 kPa for 4 hours are measured under conditions of a load of 2.16 kg and a temperature of 15°C higher than the melting point in accordance with JIS K7210.SELECTED DRAWING: None
