Genuine Bambu Lab PLA Basic in refill format — the same vacuum-sealed, RFID-chipped roll that loads directly into AMS, just without the spool. If you've already got a reusable spool on hand, this is the efficient reload: lower cost per kilogram, same print performance, same automatic temp-setting when AMS reads the chip. You're on the Refill page — pick the right format before you add to cart: Refill (this page): Filament roll only. Requires a Bambu reusable spool or compatible empty spool to load onto. With Spool: Comes ready to load as-is — the right pick for a new color or your first order. Stock varies by color and weight — the variant selector above reflects live availability. Why Makers Keep This Stocked RFID Chip in the Roll Core: AMS reads it automatically and dials in nozzle and bed temps for you — no manual profile selection, no guessing. 1.75mm ± 0.03mm Diameter Consistency: Tight tolerance means steady extrusion and low clog risk across long runs and high print speeds. Low Warp, High Bed Adhesion: Sticks cleanly to PEI, textured, and cool plates. Releases predictably when the bed cools — no prying, no adhesion drama. AMS Ecosystem Native: Compatible with AMS, AMS 2 Pro, AMS HT, and AMS Lite out of the box. Also runs on any standard FDM printer that takes 1.75mm PLA. 1 kg / 2.2 lb Net Weight: Spool-free roll, so you're getting filament weight — not spool weight. Real-World Maker Tips The RFID Chip Lives in the Roll, Not the Spool. AMS reads the tag embedded in the filament roll's cardboard core — not in the spool itself. You keep full AMS smart features (auto temp, filament ID, runout detection) whether you're using Bambu's reusable spool or a compatible third-party hub. Don't Dry It If It's Fresh From the Bag. A freshly opened, vacuum-sealed roll doesn't need drying before use. If the roll has been sitting open for more than a few days — especially in a humid shop — run it at 55°C for 8 hours. Moisture shows up as popping or crackling sounds during extrusion and rough surface texture on finished parts. Max Speed Is a Ceiling, Not a Target. The 300mm/s figure is a material ceiling under ideal conditions. Real-world top speed depends on your specific hotend, cooling, and profile. Start at your printer's tested PLA Basic profile and push from there.
