YOOPAI Dual Color Silk PLA Filament, 1.75mm Blue Silver, 1kg Spool

The 1.75mm blue-and-silver dual-color format gives printed parts a shifting, two-tone look that changes with lighting and viewing angle. Its silk finish adds a glossy, metallic-like appearance, making this PLA filament a natural fit for display pieces, decorative models, and creative gifts where color is part of the design.

Choose this coextruded filament when you want a print to carry more visual variation than a single-color spool can provide. For functional or simple-color projects, a standard PLA may suit the brief, for décor and models meant to catch the eye, the blue-silver finish brings a distinctive look directly from the printer.

Technical details

• Material: Polylactic acid (PLA)
• Filament diameter: 1.75mm, with ±0.03mm accuracy
• Color: Blue and silver, dual-color silk
• Spool size: 1kg
• Recommended nozzle temperature: 190–215°C
• Recommended bed temperature: 30–60°C
• Recommended printing speed: 50–80mm/s

The consistent diameter is designed to support steady feeding and even extrusion on compatible FDM printers. YOOPAI describes the formula as optimized for layer adhesion and reduced shrinkage, helping support clean-looking prints. The spool is dried before packaging and vacuum-sealed with desiccant to help protect the filament from moisture. For a more pronounced silk surface, the manufacturer recommends printing at a slower speed within the stated range.

Everyday use

This filament suits projects where the surface finish matters as much as the shape: display models, home décor, and small creative pieces can all make use of the shifting blue-and-silver appearance. The color transition adds visual interest without requiring a separate color change during the print, while the glossy finish gives decorative objects a polished look as they come off the printer.

It is made for most 1.75mm FDM 3D printers, so it can fit into an everyday filament workflow when the printer supports that diameter. Buyers have shared positive impressions of how it prints, while feedback on color appearance is mixed. Some also report differing experiences with adhesion, clogging, brittleness, and winding, so following the recommended temperature and speed range is a practical starting point for a new spool.

What you get

The product is a 1kg spool of blue-silver dual-color silk PLA filament. Use it for a single decorative print or keep it available for projects where a two-tone, high-gloss finish can contribute to the final design. The spool format makes the filament ready to load into a compatible printer and select for the next project.

Before you decide

Which printers can use this filament? It is designed for most FDM 3D printers that use 1.75mm filament. Check that your printer uses this diameter before loading the spool.

What settings does YOOPAI recommend? The suggested nozzle temperature is 190–215°C, the bed temperature is 30–60°C, and printing speed is 50–80mm/s. Slower speeds can help bring out the silk surface finish.

How does the color look on a finished print? The blue-and-silver coextrusion creates a color-shifting effect that varies with lighting and viewing angle. That changing appearance is especially suited to pieces intended for display.

Buying verdict

For makers choosing filament for decorative prints rather than a plain, uniform-color finish, this 1.75mm blue-silver silk PLA combines a shifting two-tone effect with a glossy surface and a 1kg spool. It is a practical match for display models, décor, and gifts where the material’s color and sheen help the printed form stand out.
