YOOPAI SUNLU Silk PLA+ 1.75mm Gold – 1kg Spool, Chrome‑Like Gloss Finish & Stable Feeding

This upgraded PLA+ combines a satin, metallic sheen with a formulation tuned for stable feeding and strong layer adhesion. The 1.75mm diameter is held to ±0.02mm tolerance for consistent flow, and each 1kg spool ships vacuum sealed with desiccant on a reusable reel to reduce moisture and storage waste. Ideal for decorative models and prototypes where surface appearance is a priority, this filament works with a wide range of consumer FDM printers.

How does this filament achieve its chrome‑like gloss without extra finishing?

The silk PLA+ resin contains additives and an optimized extrusion profile that produce a natural satin‑metallic finish as the part cools. That reduces or eliminates the need for sanding, polishing, or painting for many decorative pieces.

• Silk formula yields a smooth, reflective surface straight from the nozzle.
• Lower shrinkage and improved layer bonding preserve finish quality.
• Recommended slower print speeds enhance the silk effect.

What print settings work best with YOOPAI SUNLU Silk PLA+?

For dependable results, use a nozzle temperature between 205–215°C and a heated bed at 60–80°C. Print speeds of 30–60mm/s are suggested; slower speeds enhance surface sheen and reduce stringing.

• Nozzle: 205–215°C for consistent extrusion and gloss.
• Bed: 60–80°C to reduce warping and improve first layer adhesion.
• Speed: 30–60mm/s; slow passes for best silk finish.
• Diameter tolerance: ±0.02mm for steady flow and fewer clogs.

Will this filament cause jams or tangles during long prints?

Each spool is mechanically wound and inspected to minimize tangles, and the tight diameter control helps prevent under‑ or over‑extrusion that can lead to clogs. Vacuum sealing with desiccant reduces moisture, lowering bubbling and stringing risks during extended runs.

• Mechanically wound spool reduces risk of tangles and feed issues.
• Precision diameter means consistent extrusion through long prints.
• Vacuum-sealed packaging with desiccant protects filament from humidity.

Who is this for: Creators who value finish and reliability — hobbyists sculpting display models, designers producing showpieces, educators demonstrating print quality, and makers refining prototypes. If you need a gold, chrome‑like sheen with predictable extrusion and minimal postwork, the YOOPAI SUNLU Silk PLA+ 1.75mm spool is built to deliver consistent, visually striking results on compatible consumer FDM printers.
