3D 3D POLYMER RESIN COMPOSITION 3D PRINTING FILAMENT INCLUDING THE SAME AND METHOD FOR PRODUCING 3D PRINTER FILAMENT

摘要

The present invention relates to a polymer resin composition, a filament for three-dimensional (3D) printers including the same, and a method for producing the filament for 3D printers. To this end, the polymer resin composition comprises: a polyester copolymer A comprising a residue of a dicarboxylic acid component containing terephthalic acid and a residue of a diol component containing dianhydrohexitol; a polyester copolymer B comprising a residue of a dicarboxylic acid component including terephthalic acid and a residue of a diol component except dianhydrohexitol; and an impact reinforcement agent.
