Silk Dual-Color PLA with Bold Midnight Contrast
Bambu Lab PLA Silk Midnight Blaze features a striking blue-and-red dual-color composition, delivering a smooth silk texture and high-gloss surface that brings depth and drama to decorative 3D prints.



Dynamic Color Shifts from Every Angle
By blending deep blue and vivid red silk tones into a single filament strand, Midnight Blaze creates dynamic color changes as the model is viewed or rotated, producing eye-catching visual effects.

Elegant Results in a Single Print
Ideal for vases, sculptures, and decorative designs, PLA Silk Gradient adds depth, movement, and brilliance through its seamless silk-like color blending.

Printing Tips
• Although PLA Silk Multi-Color is thoroughly dried and vacuum-sealed prior to shipping, variations in transport conditions may affect its moisture level. We strongly recommend drying it right after opening and storing it in a sealed container with desiccant or AMS. Repeat drying and moisture-proofing before each long-term storage period.
• Drying conditions: 55℃ for 8 hrs. Store in a dry environment after use. Dry before use if the material absorbs moisture. For more details please refer to: Filament drying instructions on WIKI.
• It’s strongly recommended to reduce the outer wall speed to 40 mm/s to optimize print quality.
• When printing with PLA Silk Dual Color filament, there is a small chance of filament rotation, potentially causing uneven color transitions. The A-series printers have a higher risk due to their special structure, so use of this filament with A-series printers is not recommended.
Gradient Effects
• The gradient effect depends on the amount of filament used, which can be influenced by adjusting sparse infill density, print quantity, or the filament spool starting point.
• Each color segment in Bambu PLA Silk Gradient spans approximately 20m (65g+).
• Using 40m (125g+) of filament guarantees at least one two-color transition.
• For four-color transitions (e.g., Bambu PLA Gradient – Dawn Radiance), using 80m (250g+) or more ensures the full effect.
