POLYMER RESIN COMPOSITION, 3D PRINTER FILAMENT COMPRISING SAME, AND METHOD FOR MANUFACTURING 3D PRINTER FILAMENT

摘要

The present invention relates to a polymer resin composition, a 3D printer filament comprising same, and a method for manufacturing the 3D printer filament, the polymer resin composition comprising: a polyester copolymer A, which comprises a residue of a dicarboxylic acid component including terephthalic acid and a residue of a diol component including a dianhydrohexitol; a polyester copolymer B, which comprises a residue of a dicarboxylic acid component including terephthalic acid and a residue of a diol component excluding the dianhydrohexitol; and an impact modifier.
