Spectrum PLA Silk Filament 1.75 mm 1 kg Ruby Red. The satin-like surface results in silky-glossy printed objects! The Spectrum PLA filament is made from raw materials specifically designed for 3D printing. High-quality PLA that stands out for its excellent flow properties. New from Spectrum with ID-Spool-Tracking! The filament is vacuum-packed on a transparent spool. Printing temperature: 210-240 °C. Heated bed temperature: Not necessarily required due to the low warp effect. Recommended: approx. 0 – 45 °C. Very low warp effect. Spool size: spool diameter: 200 mm, spool height: 76 mm, hub hole diameter: 53 mm. Technical details: specific weight: 1.24 g/cc, MFR (210 °C / 2.16 kg), g/10 min: 6 (D1238), heat distortion temperature: 55 °C, tensile strength: 60 MPa (D882), tensile modulus: 3.6 MPa (D882). Storage: cool and dry (15-25 °C) and away from UV light. This significantly improves durability. Every desktop 3D printer has its own unique characteristics. Therefore, you may need to experiment a bit with the temperature settings to achieve the best results. To obtain optimal results for your prints, you need to consider variables such as the nozzle diameter of your 3D printer, your print speed settings, and layer height.
