POWDER FOR SOLID FORMING, RESIN POWDER, PRODUCTION APPARATUS OF SOLID FORM, AND PRODUCTION METHOD OF SOLID FORM

摘要

PROBLEM TO BE SOLVED: To provide powder for solid forming, capable of producing a solid form having excellent heat resistance.;SOLUTION: The powder for solid forming is characterized by that: in a differential scanning calorimetry, measured at 10°C/min in accordance with ISO 3146, when a heat of fusion of an endothermic peak obtained in rising a temperature to a temperature 30°C-higher than a melting point is defined as Q1 and when the temperature is lowered to 20°C or under at a rate of 10°C/min and a re-heat of fusion further rising the temperature to a temperature 30°C-higher than the melting point at a rate of 10°C/min is defined as Q2, a ratio of the Q1 and the Q2 (Q1/Q2) is 1.10 or over; and a solid form obtained by hardening the powder for solid forming P shows deflection temperature under load under a flexure stress of 1.8 MPa measured in accordance with JIS K7191 (ISO 75) is 60°C or over.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
