Sunlu PLA+ Silk Dual Color Filament Pink and Gold — PLA+ Silk dual-color 3D printing filament

Sunlu PLA+ Silk Dual Color Filament in pink and gold combines enhanced PLA+ mechanical properties with a glossy, silk-like finish and a two-tone appearance. The Multi Color technology produces a multicolored effect from a single filament so finished prints change subtly with viewing angle and lighting. The filament is intended for FDM/FFF 3D printers and is suitable for decorative objects, figurines, gadgets, prototypes and hobby models where both precision and visual impact matter.

Advantages

The filament provides a smooth, silky sheen and consistent glossy surface that makes prints look refined straight from the printer without additional polishing. It also offers improved mechanical characteristics compared with standard PLA: higher tensile strength, increased flexibility and enhanced impact resistance for more durable prints. Dimensional accuracy, low shrinkage and uniform diameter promote stable feeding and reliable results across many FDM printers.

Suitable for

• Decorative objects and display models
• Figurines and artistic prints with two-tone visual effects
• Prototypes and gadgets requiring good surface finish
• Hobby and cosplay parts where appearance is important

When it may not be suitable

This filament is not intended for high-temperature functional parts exposed to continuous heat above its deformation range; it has a Vicat softening temperature around 54 °C and heat deflection near 57 °C. For applications demanding high thermal resistance or food-contact certification, choose a material rated for those specific requirements.

• Density: 1.23 g/cm³
• Vicat softening temperature: 54 °C
• Heat deflection temperature: 57 ±3 °C
• Melting temperature: 164 °C
• Melt flow rate: 7 ±2.5 g/10 min
• Tensile strength: 50 ±4 MPa
• Elongation at break: 11 ±3 %
• Flexural strength: 78 ±5 MPa
• Flexural modulus: 2600 ±300 MPa
• Impact resistance (X-Y): 78 ±5 kJ/m²

How to use

Load the filament into a compatible FDM/FFF 3D printer and set the hotend temperature according to your printer and nozzle (start around the material’s melting point and adjust as needed). Use a print bed preparation method appropriate for PLA variants (glue stick, PEI or blue tape) and moderate print speeds to preserve the silk surface. Ensure proper retraction and cooling settings to minimise stringing and to maintain the glossy finish. Allow prints to cool fully before handling to avoid deformation.

What to consider before purchase

• Check printer compatibility with PLA+ and recommended nozzle temperatures
• Consider the filament’s thermal limits for any functional parts
• Verify spool diameter and mounting fit for your printer

Usage recommendations

For best visual results with Sunlu PLA+ Silk Dual Color Filament, print at moderate speeds with adequate part cooling and use a fine layer height; this preserves the silk sheen and two-tone effect while maintaining dimensional accuracy.
