Bambu Lab Reusable Spool

Bambu Lab Reusable Spool

Every roll of filament you buy on a spool leaves you with a spool. Bambu's refill system flips that around: you buy the spool once, then buy filament as a bare coil with its RFID tags attached. Twist the two halves apart, seat the refill, twist until it clicks, and the AMS reads it exactly as it would a factory roll. No tools, no tape, no adapters.

The spool keeps the standard Bambu geometry — 200 mm outer diameter, 55 mm hub, 67 mm wide — so it feeds the AMS, AMS lite, AMS 2 Pro, AMS HT and external spool holders without modification. Bambu rates the whole refill approach at a minimum 20% reduction in plastic per roll of filament, which adds up quickly in a school lab or a print farm.

How the refill workflow actually goes

• Twist the narrow half of the spool anticlockwise to separate it from the wide half.
• Line the locator block up with the notch on the side of the refill — the one next to the RFID tag — and drop the coil onto the wide half.
• Refit the narrow half and rotate clockwise until you hear it lock.
• Snip the plastic tabs holding the coil, feed the filament through the slot, and apply the refill's sticker to the spool side so you know what's on it.

Refills carry an identical RFID tag on each side, so orientation doesn't matter — load it whichever way your unspooling direction wants.

Which configuration is right for you?

Both versions are the same shape, the same weight and fit the same hardware. The only thing that separates them is how much heat the plastic will take — which in practice means what you can dry on them.

	Low Temp (≤70°C)	High Temp (≤90°C)
Material	ABS	ABS+PC alloy
Colour	White	Black
Heat resistance	≤70°C	≤90°C
Suits these refills	PLA, PLA Matte, PETG and other low-temp materials	ABS, ASA, PA6-GF, ABS-GF, PAHT-CF, PET-CF, PA6-CF, PC, TPU 95A HF — and PLA/PETG too
High-temperature drying	Not rated above 70°C	Yes — stays stable through 80–90°C cycles
Bambu model code	RSP001	RSP002
Pick it if…	You print PLA and PETG and want the cheapest way to keep buying refills	You run engineering materials, or want one spool type that covers everything

Short answer: if your printer mostly runs PLA and PETG, the Low Temp spool is all you need. If you dry nylon, CF-filled or ABS/ASA refills at 80°C or more, take the High Temp — a softened spool in the dryer is how rolls end up tangled.

What's in the box

• 1 × spool wide piece
• 1 × spool narrow piece
• 2 × spacing shims (for smaller-diameter refills)

Filament is not included — pair this with any Bambu filament refill.

Who it's for

• Anyone switching to refills — you need at least one spool per colour you want loaded at a time.
• Multi-colour AMS users — keep four loaded and swap coils rather than whole spools.
• Schools and makerspaces — fewer empty spools in the bin and a lower per-roll cost on consumables.
• Small businesses and print farms — refills take less shelf space and less packaging per kilo.
• Anyone who has cracked or warped a spool and needs a straight replacement that the AMS will still read.
