  "summary": "Polyamide 6 (PA6, nylon 6) reinforced with 30 % glass fibre is a stiff, semicrystalline composite. Ensinger sells one grade, TECAMID 6 GF30 black, as machined stock shapes; its datasheet gives a density of 1.36 g/cm3 and a tensile strength of 98 MPa (DIN EN ISO 527-2). Spectrum sells PA6 Low Warp GF30 as a 3D printing filament with a density of 1.34 g/cm3 and a tensile strength of 80 MPa (EN ISO 527-1, dry). The two grades are different products, so their rows are not a ranking.\n",
