The Gembird 3DP-PLA-SK-01-RP is a silk rainbow PLA filament designed for 3D printers that support a 1.75 mm diameter. This specific spool features a red and purple color transition, allowing you to create visually striking models with a glossy, metallic-like finish. Each 1 kg roll provides 340 meters of material, which is printed at temperatures ranging from 190°C to 220°C. To support more sustainable practices, the filament is wound on a cardboard spool made from PAP 20 material. This makes it a practical choice for hobbyists and designers who want to produce colorful, decorative objects while reducing plastic waste from the packaging.
