N is determined by depositting the powder in a softened or melted state to form a structure in a temperature range between the resin material's minimum molding temperature and maximum molding tempeature+100° C.; measuring the structure's porosity Rn at 12 locations by image analysis; and dividing the variance of porosity Rn by the average porosity Rn. The minimum and maximum molding temperatures are the lowest and highest heater temperatures at which the resin material can be molded at a pressure of 3500 psi by injection molding, respectively.Type: GrantFiled: June 29, 2015Date of Patent: May 26, 2020Assignee: FUJIMI INCORPORATEDInventors: Kazuto Sato, Hiroaki Mizuno, Hiroyuki Ibe, Fumi Shinoda, Kyohei Ota
