Filament BambuLab PLA Silk Dual Color 1.75 mm 1 kg with reusable spool – Neon City is a silk-grade PLA filament designed for FDM/FFF 3D printers that accept 1.75 mm filament. The dual-color strand and silk formulation deliver glossy, satin-like surface finishes suited to visible parts and decorative objects. Supplied on a reusable spool, the filament is intended for detailed models, visual prototypes and decorative parts where smooth, reflective surfaces and clear color transitions are required.
Advantages
This PLA silk filament provides a smooth, satin sheen that reduces post-processing for many visual applications. The dual-color construction creates continuous color variation during printing, producing attractive gradients and two-tone effects without changing filament. The reusable spool supports cleaner storage and easier handling, while the 1.75 mm diameter ensures compatibility with a wide range of desktop FDM/FFF printers. The material prints at standard PLA temperature ranges and is dimensionally stable for most non-functional decorative and prototype parts.
Suitable for
- Decorative models and display pieces with visible surfaces
- Visual prototypes and concept models where appearance is important
- Miniatures, figurines and collectibles with fine surface detail
- Parts requiring satin or glossy finish without annealing or polishing

How to use
Load the 1.75 mm filament into a compatible FDM/FFF printer according to the printer manufacturer's filament loading procedure. Use typical PLA print temperatures (refer to your printer or slicer for exact values) and moderate print speeds to preserve the silk surface and color transitions. For best first-layer adhesion, prepare the build surface with the recommended method (glue stick, PEI, blue tape, or heated bed settings) and ensure proper bed leveling. Monitor the first layers to confirm consistent extrusion and stable adhesion, then proceed with the intended print job.
Usage recommendations
To maximize surface quality, print at lower layer heights (e.g., 0.1–0.2 mm) and use a well-calibrated extrusion multiplier. Avoid excessive retractions and high print speeds that can disrupt the dual-color gradient; if post-processing is required, light sanding followed by gentle polishing will enhance the silk sheen. Store the reusable spool in a dry environment or sealed bag with desiccant to maintain filament dryness and print reliability.
