Powder materials and three-dimensional shapes for 3D printers

Abstract

A powder material for 3D printers and a three-dimensional model using the same are provided. This powder material can produce three-dimensional models with good appearance, mechanical properties, and excellent heat resistance. A powder material (X) is a 3D printer powder material (X) comprising polybutylene terephthalate resin powder (I), wherein the enthalpy ΔHm1 of the polybutylene terephthalate resin powder (I) measured by a differential scanning calorimeter and heated from 30°C to 260°C at a heating rate of 20°C / min is less than 50 J / g, and the enthalpy ΔHm2 measured in the second run is more than 30 J / g.
