SUNLU PLA+ Silk 1.75mm Filament 1kg Spool

Transform your 3D prints into stunning works of art with SUNLU PLA+ Silk Filament, the premium enhanced material that combines the ease of PLA printing with a breathtaking glossy, silk-like finish that requires no post-processing polishing. This advanced PLA+ formulation incorporates specialized thermoplastic elastomer (TPE) additives that create a luxurious sheen and smooth silky surface texture, perfect for decorative objects, artistic creations, and display pieces that demand visual impact. With enhanced mechanical properties including improved toughness and impact strength up to 8KJ/m², this silk filament delivers both stunning aesthetics and superior durability compared to standard PLA.

Engineered for effortless printing, SUNLU PLA+ Silk maintains the user-friendly characteristics that make PLA the go-to choice for makers while elevating surface finish to professional levels. The filament feeds smoothly without clogging, features exceptional dimensional accuracy of ±0.02mm, and produces consistent results with excellent layer adhesion and minimal warping. Available in a spectacular range of metallic and vibrant colors, this silk filament creates prints with an intermediate level of reflectiveness that's more sophisticated than matte finishes yet not overly glossy, making it ideal for jewelry, decorative models, artistic sculptures, and any project where visual appeal is paramount.

Key Features:

Stunning Silk-Like Finish: Advanced TPE additives create a genuine silk-like sheen and smooth surface texture that outshines standard PLA without requiring any post-print polishing or finishing work.

Enhanced PLA+ Performance: Superior mechanical properties with improved toughness, impact strength up to 8KJ/m², and better layer adhesion compared to regular PLA while maintaining the same easy printing characteristics.

Professional Print Quality: Exceptional dimensional accuracy of ±0.02mm ensures smooth extrusion, consistent results, and eliminates nozzle clogging for reliable professional-grade prints every time.

Optimal Light Reflection: Intermediate reflectiveness level provides sophisticated visual appeal - more elegant than matte finishes yet not overly glossy, perfect for display pieces and artistic applications.

User-Friendly Printing: Maintains PLA's forgiving print characteristics with no heated bed requirement, excellent adhesion, minimal warping, and compatibility with most FDM 3D printers.

Premium Color Range: Available in spectacular metallic finishes and vibrant colors with high purity and saturation that showcase the silk effect beautifully across diverse creative applications.
