SUNLU Silk PLA+ 3D Printer Filament - Red Gold, 1.75mm, 1kg
SUNLU Silk PLA+ Dual Color is a genuine two-colour silk filament: two glossy shades (red gold) are co-extruded along the full length of the spool, so the colour you see shifts with the viewing angle of the part. Rotate a finished print and it flips between the two tones - a striking effect for vases, figurines and art pieces, with no painting required.
Every spool is produced with laser-monitored diameter control and held to a tight 1.75 ± 0.02 mm tolerance, keeping extrusion smooth and consistent through long prints. SUNLU's fully automated winding lays the filament 100% neatly on the spool - no knots, no tangles, no mid-print failures. It is clog, bubble, tangle and warping resistant, and runs on virtually any 1.75mm FDM printer - Bambu Lab, Creality, Anycubic, Prusa, Elegoo and more - with no special tuning.
Key Features
- Silky glossy finish: smooth, shiny surface straight off the bed - no polishing or painting needed.
- 100% neatly wound: SUNLU's automated spooling prevents knots and tangles that ruin prints.
- Precise 1.75 ± 0.02 mm diameter: laser-monitored consistency for even extrusion and clean layers.
- Easy to print: prints like regular PLA - low warping, great layer adhesion, no enclosure needed.
- Reusable 3rd-generation spool: multi-hole design dries thoroughly and works with spool refills.
- Wide compatibility: works with 99% of 1.75mm FDM 3D printers, including AMS and AMS Lite systems.

Good to know
- The exact split between the two colours depends on part size, orientation and layer height - rotate the model in your slicer to place each shade where you want it.
- Silk PLA+ absorbs moisture over time. If you hear popping or see stringing, dry the spool at 50-55°C for 4-6 hours.
- Store sealed with desiccant when not in use.
