eSUN PLA-Silk Bronze is a glossy, silk-finish modified PLA filament for FDM 3D printing, supplied in a 1.75mm diameter with a 1kg net weight. It gives printed models a bronze metallic-like appearance with a smooth, reflective surface that helps reduce visible layer lines. Easy printing and support removal make it suitable for decorative figures, artistic models and display projects, with print speeds up to 200 mm/s.
⭐ eSUN PLA-Silk combines a silky metallic-like sheen, smooth surfaces, easy printing and less visible layer lines, with easy support removal for attractive decorative and artistic prints.
Compatible with FDM printers supporting PLA, 1.75mm filament and nozzle temperatures up to 230°C, including printers from:
✅ Bambu Lab ✅ Creality ✅ Prusa ✅ Anycubic ✅ ELEGOO ✅ Other Brand
🔹 Bambu Lab: AMS, AMS Lite, AMS 2 Pro and AMS HT support PLA, subject to spool dimensions and third-party filament settings.
🔹 Creality: CFS and CFS Lite support PLA; CFS Lite specifically lists PLA Silk among supported materials, subject to spool and printer compatibility.
🔹 Anycubic: Anycubic does not recommend non-official PLA Silk such as eSUN for use inside ACE Pro or ACE 2 Pro.
🔹 Prusa: MMU3 supports PLA, subject to printer and feeding-system compatibility.

⭐ Why Choose eSUN PLA-Silk?
🔹 A smooth, silky gloss creates a metallic-like reflective finish without requiring painting or polishing for the basic shine effect.
🔹 A refined and uniform surface helps minimize visible layer lines and enhances the appearance of detailed decorative prints.
🔹 Modified PLA offers easy printing, low shrinkage and stable extrusion with suitable settings.
🔹 Supports are easier to peel away while maintaining relatively smooth contact surfaces.
🔹 Supports printing speeds up to 200 mm/s, while reducing outer-wall speed can improve surface gloss.
🔹 Bronze features a muted metallic bronze tone with a slightly warm grey-olive appearance and a silky sheen that changes with lighting and viewing angle, making it suitable for statues, artistic objects and decorations.
⚙️ Recommended Printing Settings

💡 Printing Recommendations and Usage Conditions
🔹 Drying: 50°C for more than 8 hours when needed, according to the official TDS.
🔹 eSUN recommends reducing outer-wall printing speed to enhance the silky gloss of printed models.
🔹 Overhangs and suspended features require effective cooling. Reduce printing speed or modify overhang angles when necessary.
🔹 Keep the printer enclosure open when chamber temperatures are high. If ambient temperature exceeds 32°C, cooling the printing environment is recommended.
🔹 Optimize Z seam alignment, layer starting points and travel paths, and reduce printing speed as needed to improve surface quality.
🔹 Store unused filament in a cool, dry place in an airtight container or sealed bag with desiccant.
