Whether you’re printing basic PLA, durable PETG, flexible TPU, or eye-catching specialty colours, our refill system gives you the freedom to print more for less. Designed to fit perfectly on Bambu Lab’s reusable spools, these refills provide smooth AMS feeding, reduced plastic waste, and top-tier material consistency across every roll.
Why Choose Our Bambu-Compatible Refill Filaments
Here’s what makes our refill ecosystem the best choice for Bambu Lab users and high-volume printing environments:
1. Fully AMS-Compatible Refill System
Each refill is engineered to match the dimensions and tension requirements for reliable performance inside Bambu’s AMS. Simply snap the filament onto your reusable spool and enjoy tangle-free, jam-free feeding across multi-material or multi-colour prints.
2. Eco-Friendly & Reduced Waste
Refill rolls eliminate the need for disposable plastic spools, dramatically lowering waste. Most options use a lightweight cardboard core, helping reduce environmental impact while streamlining AMS loading.
3. Multiple Material Types for Every Application
• PLA (Standard, Dual-Colour, Tri-Colour, Rainbow)
Easy to use, vibrant, and perfect for everyday prints. Great for hobby projects, prototypes, décor, toys, and AMS colour-switching.
• PETG
Stronger and more temperature-resistant than PLA. Ideal for functional parts, outdoor components, brackets, and prototypes needing durability.
• TPU (Flexible)
A flexible and elastic material for grips, wearables, bumpers, gaskets, toys, and shock-absorbing components — all AMS friendly when loaded correctly.
• Specialty & Effect Filaments
Includes matte finishes, gradients, silk-style dual tones, colour-shift options, and more. Add visual impact without sacrificing AMS compatibility.
4. High Precision & Reliable Extrusion
All refill materials maintain a strict diameter tolerance of ±0.05mm, ensuring stable extrusion and improved print success on Bambu Lab printers. Each roll is wound clean and tight to prevent tangling or layer overlaps.
5. Smooth Loading & Broad Printer Compatibility
While optimized for Bambu Lab AMS systems, these refills also work w
