Silk PLA+ in Silky Black Hills Gold delivers a satin-smooth, reddish-gold finish that echoes the elegant sheen of Black Hills Gold jewelry. Sized at 1.75 mm, this filament is formulated for dependable extrusion and exceptional surface quality, making intricate and color-rich prints easier than ever.
What makes 3D-Fuel Silk PLA+ stand out
- Durability and adhesion: Silk PLA+ offers stronger layer-to-layer bonding than many glossy silk PLAs on the market, delivering prints that resist cracking and delamination while preserving a silky finish.
- Toughness hierarchy: While not as rigid as our Standard PLA+, it’s noticeably tougher and more durable than other silk formulations you may have tried, helping parts endure handling and assembly.
- Virgin, U.S.-made resin: The base polymer uses 100% virgin NatureWorks Ingeo 4043d PLA resin, manufactured in the United States for consistent performance and quality control.
- Pleasant extrusion aroma: A barely noticeable, sweet smell during printing adds a more pleasant printing experience compared with some other filaments.
- Color and finish: The silk, satin-like surface yields a warm, reddish-gold hue with a soft luster that stands out in multi-color prints—especially in layered, jewelry-inspired designs or decorative pieces.
- Printer compatibility and profiles: Print using the Generic Silk PLA profile for compatible 3D printers; ideal for multi-color systems like the Bambu Lab AMS.
- Made for the AMS ecosystem: The 1 kg reel is designed to fit the Bambu Lab AMS and AMS Lite, with packaging that keeps the filament dry and ready to print.
Printing and quality you can trust
- Printing settings: Hotend 190–230°C; Bed 0–60°C. Suitable bed surfaces include Bambu High Temp Plate, Bambu Cool Plate, Bambu Textured PEI, heated bare glass, blue painter’s tape, BuildTak, and WhamBam variants. Recommended print speeds range from 60 to 250 mm/s, with potential increases at higher temperatures for faster production.
- Consistent diameter and ovality: A sophisticated multi-axis laser measurement system monitors filament diameter and ovality in real time during production, reducing the risk of extrusion glitches caused by diameter variation.
- 1 kg, moisture-protected packaging: A full 1 kg spool arrives on a durable reel, vacuum-sealed with a desiccant packet to guard against moisture before and during use.
- AMS-friendly spool design: The reel is engineered to work smoothly with the Bambu Lab AMS, supporting reliable automated material swapping in multi-color builds.
- Independent quality testing: The 3D-Fuel test lab evaluates performance across multiple printer brands and configurations to ensure the filament you buy prints well in real-world scenarios.
- US manufacturing: All 3D-Fuel filament is produced in U.S. facilities, giving you traceable quality and production controls from spool to print.
Ideal applications
- Colorful, decorative parts and artistic pieces that benefit from a luxurious satin finish.
- Durable prototypes and functional parts that require good layer adhesion without sacrificing aesthetics.
- Multi-color projects where Silk PLA+ can serve as a striking accent or feature color in a broader printbed palette.
