## Summary description

Sunlu PLA+ Silk filament in black is a 1.75 mm PLA+ silk-type 3D printing material offering improved layer adhesion and a glossy, silk-like surface finish. Designed for FDM/FFF printers compatible with 1.75 mm filament, it is suitable for decorative parts, prototypes and models where smooth, shiny appearance and ease of printing are desired.

## Long description

Sunlu PLA+ Silk (Black) is a 1.75 mm PLA+ silk-type filament designed for FDM/FFF 3D printers. It delivers a glossy, silk-like surface that reduces the need for post-processing and is intended for decorative parts, prototypes and models where a smooth, shiny appearance and good dimensional accuracy are important.
Advantages
The filament produces a striking glossy finish that gives printed models an elegant appearance without additional polishing. It feeds smoothly with low warping and minimal shrinkage, which helps achieve consistent, detailed prints. Dimensional accuracy and a uniform diameter support stable material feeding and repeatable results across different printers.
Suitable for
Decorative models and display pieces
Prototypes and visual mock-ups
Artistic and creative projects needing a silk-like sheen
Users seeking easy-to-print materials for 1.75 mm FDM/FFF printers
When it may not be suitable
This filament is not intended for high-temperature applications or parts that must withstand continuous heat above the material's heat deflection range. It is primarily a visual and general-purpose PLA+ material rather than a high-performance engineering plastic.
Key specifications

Elongation at break: 6.3%
Flexural strength: 65 MPa
Flexural modulus: 2760 MPa
Impact strength: 4.2 kJ/m²
How to use
Load the 1.75 mm filament into an FDM/FFF printer and use typical PLA+ printing temperatures around the material's melting range as a starting point. Sunlu PLA+ Silk feeds smoothly and often does not require a heated bed, though a heated bed or adhesive surface can improve first-layer adhesion. Calibrate extrusion and print settings for optimal layer bonding and surface finish; adjust print speed, retraction and cooling to reduce stringing and achieve the desired glossy appearance.
What to consider before purchase
Confirm printer compatibility with 1.75 mm PLA-type filaments
Consider the filament's heat resistance limits for functional parts
Decide if a glossy, silk-like surface finish is the primary requirement
Usage recommendations
For best results, start with manufacturer-recommended or PLA+ typical temperatures, tune retraction and cooling for minimal stringing, and test layer height and print speed to preserve the silk-like gloss while maintaining dimensional accuracy.
