## Summary description

Sunlu PLA+ Silk Forth-Color filament is a multicolor PLA+ silk-finish material (blue, purple, orange, yellow) designed for FDM 3D printers. It provides visually striking gradient color transitions and a glossy, silk-like surface suitable for decorative items, prototypes and display pieces. Compatible with standard PLA print settings; ideal for aesthetic prints.

## Long description

Sunlu PLA+ Silk Forth-Color filament in blue, purple, orange and yellow is a multicolor PLA+ material with a silk-like glossy finish for FDM 3D printing. Using Multi Color technology, a single filament produces gradient color transitions that change with viewing angle and lighting. The filament is suitable for decorative prints, figurines, gadgets, prototypes and other projects where both visual effect and dimensional accuracy are important.
Advantages
The filament combines a silky sheen with a smooth surface, delivering attractive prints straight from the printer without mandatory post-processing. It also improves mechanical performance compared with standard PLA: higher tensile strength, increased flexibility and good impact resistance make prints more durable for both display and functional uses. Tight diameter tolerance and low shrinkage ensure stable feeding and consistent print quality across a wide range of FDM machines.
Suitable for
Decorative items and display models
Figurines and collectibles
Prototypes and visual models
Gadgets and non-load-bearing functional parts
Experiments with multicolor and gradient effects
When it may not be suitable
This PLA+ silk filament has a silk finish and improved mechanical properties, but it is not formulated for high-temperature or load-bearing engineering applications. Its heat deflection and Vicat softening temperatures limit use in environments above roughly 50–60 °C. For parts that require high continuous heat resistance or certified engineering plastics, choose a material specifically designed for those conditions.
Key specifications
Color: blue / purple / orange / yellow (multicolor gradient)
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
Dimensional tolerance: ±0.02 mm
How to use
Print with standard PLA settings on most FDM printers. Use a nozzle temperature around the material's melting range (commonly 200–220 °C depending on your printer) and a heated bed if available to improve adhesion; keep bed temperature moderate to match PLA+ behavior. Ensure the filament spool feeds smoothly and calibrate extrusion multiplier if necessary to account for the silk finish. Allow prints to cool gradually to preserve surface gloss and dimensional accuracy.
What to consider before purchase
Intended use temperature — not suitable for continuous exposure above ~50–60 °C
Compatibility with your printer and nozzle diameter
Desire for glossy silk appearance versus matte or engineering finishes
Post-processing needs — typically minimal, but sanding or painting may alter the sheen
Usage recommendations
For best visual results, tune layer height and print speed to favour surface quality (lower layer height and moderate speed), and test a small sample print to verify color transitions and adhesion before large projects. Maintain consistent spool feeding and store the filament dry to preserve printability and finish.
