## Summary description

Sunlu PLA+ Silk Dual Color filament in black and blue is a dual-color PLA+ silk-grade material designed for FDM 3D printers. It provides the visual sheen of silk PLA with the usability of PLA+, suitable for decorative prints, prototypes and models that require smooth glossy finishes and reliable layer adhesion. Compatible with standard PLA print settings and single- or dual-extrusion setups that accept dual-color filament spools.

## Long description

Sunlu PLA+ Silk Dual Color (Black & Blue) is a dual-color silk-grade PLA+ filament for FDM 3D printers. The filament uses multi-color technology to deliver shifting black and blue tones that change with viewing angle and lighting. It is intended for decorative prints, figurines, gadgets, and prototypes where a glossy, silky surface and accurate detail are required.
Advantages
The material combines a silky sheen and smooth finish with improved mechanical properties compared with standard PLA. It provides vivid, glossy colours straight from the printer, reduced need for post-processing, and enhanced strength and flexibility for more durable prints. Dimensional accuracy and low shrinkage contribute to stable feeding and consistent results across many FDM machines.
Suitable for
Decorative models and figurines
Showcase pieces and display models
Prototypes and functional parts with visual emphasis
Gadgets and small enclosures requiring good surface finish
When it may not be suitable
This filament is not intended for high-temperature engineering applications: its Vicat softening temperature and heat deflection range limit continuous use at elevated temperatures. It may also be less appropriate for parts that require extreme impact resistance beyond typical PLA+ performance or for applications demanding food-safe or medical-grade certification.
Key specifications

Flexural modulus: 2600±300 MPa
Impact resistance (X–Y): 78±5 kJ/m²
How to use
Use standard PLA or PLA+ print settings on compatible FDM printers. Recommended extrusion temperatures typically align with the material’s melting range; start within common PLA+ temperatures and fine-tune for best layer adhesion and surface sheen. Ensure good bed adhesion with an appropriate build surface or adhesive, and use calibrated extrusion and dimensional settings to take advantage of the filament’s ±0.02 mm dimensional tolerance. Compatible with most single- and multi-extruder FDM printers.
What to consider before purchase
Intended operating temperature of printed parts versus the filament’s Vicat/deflection temperatures
Requirement for glossy, silk-like surface finish versus need for further post-processing
Printer compatibility with PLA+ filaments and dual-color spools
Mechanical requirements—tensile strength and flexibility relative to your application
Usage recommendations
For best results print with calibrated extrusion multiplier and moderate cooling to preserve the silk sheen. Test small samples to adjust temperature and retraction settings before committing to larger models; use a stable bed adhesion method to avoid warping and ensure consistent dual-color appearance.
