SUNLU Silk PLA+ TRI-COLOUR 1.75mm Filament 1kg Spool

The SUNLU Silk PLA+ TRI-COLOUR 1.75mm Filament transforms ordinary 3D prints into extraordinary artistic masterpieces with its revolutionary tri-color technology that displays three distinct colors from different viewing angles. This premium silk filament delivers a luxurious silky-smooth texture with a brilliant, reflective surface that requires no post-processing or polishing—your prints emerge from the printer with stunning visual appeal that radiates artistic brilliance. Unlike traditional single-color filaments, this innovative tri-color formulation creates dynamic visual depth and captivating color transitions that make every project truly unique.

Built on SUNLU's advanced PLA+ foundation, this silk filament offers an impressive 50 times the toughness of regular PLA while maintaining exceptional printability and user-friendly characteristics. The precision-engineered 1.75mm diameter with strict ±0.02mm tolerance ensures consistent flow and eliminates frustrating clogs or jams. Each 1kg spool is professionally machine-wound and vacuum-sealed with dual desiccants to maintain optimal moisture protection, while the high-purity formulation delivers excellent layer adhesion and minimal shrinkage for reliable, warp-free printing on most FDM printers.
