## Summary description

Sunlu PLA+ Silk filament, 1.75 mm diameter, 1 kg spool in Rainbow finish. This PLA+ material offers the handling and printing compatibility of PLA with a silk-like glossy surface effect, suitable for FDM/FFF 3D printers that accept 1.75 mm filament. Use it for decorative prints, prototypes and models where a smooth, shiny appearance is desired.

## Long description

Sunlu PLA+ Silk 1.75 mm 1 kg filament in Rainbow finish is a PLA-based material formulated to combine the ease of printing associated with PLA with an enhanced glossy, silk-like surface. Designed for FDM/FFF 3D printers that accept 1.75 mm filament, this spool provides a visually striking finish ideal for decorative items, display models and parts where a smooth, reflective appearance is required. The Rainbow finish produces subtle color shifts across the surface, adding visual depth without additional post-processing.
Advantages
The PLA+ Silk formulation improves layer adhesion and reduces brittleness compared with standard PLA while retaining low-warp behavior and low-odour printing. Its silk-like sheen yields a smooth, reflective surface straight off the printer, reducing the need for sanding or coating for aesthetic pieces. The 1 kg spool offers sufficient material for medium to large prints and the 1.75 mm diameter ensures broad compatibility with a wide range of consumer and prosumer FDM/FFF printers.
Suitable for
Decorative objects and ornaments with a glossy Rainbow finish
Display models and visual prototypes requiring attractive surface quality
Cosmetic housings, figurines and collectibles
School projects and demonstration prints where easy printing is preferred
Key specifications
Material type: PLA+ (silk-enhanced)
Filament diameter: 1.75 mm
Spool weight: 1 kg
Finish: Rainbow, silk-like glossy appearance
Compatibility: FDM/FFF 3D printers accepting 1.75 mm filament
How to use
Load the filament onto a compatible 1.75 mm feeder and set the nozzle temperature according to your printer and material guidelines (typical PLA+ ranges between 200–220°C; consult your printer settings). Use a heated bed if available (40–60°C recommended) to improve first-layer adhesion, although PLA+ often prints well on unheated beds with proper adhesion aids. Print at moderate speeds to preserve surface sheen and fine detail; adjust retraction and cooling settings to minimise stringing and ensure crisp layers. Allow printed parts to cool fully on the build plate before removal to avoid deformation.
Usage recommendations
Store the filament in a dry, cool environment and use sealed packaging or desiccant to prevent moisture absorption. For best surface results, calibrate extrusion multiplier and layer height; lower layer heights and slightly reduced print speed enhance the silk-like finish. If post-processing is needed, gentle sanding followed by a light polish or clear coating will retain the glossy effect.
