Which unit goes with which printer
Each brand documents compatibility only with its own printers, so the system you get is decided by the printer you buy.
| Unit | Documented printers | Most units per printer |
|---|---|---|
| Creality CFS | K2 series and Creality Hi [1] | 4 units, 16 colours on the K2 series [3] |
| Creality CFS-C | K1 Max, K1C, K1, K1 SE and 2025 versions [4] | 1 unit; multiple units not supported [4] |
| Bambu AMS 2 Pro | All Bambu Lab printers, with model-specific accessories [5] | Headline: 4 AMS 2 Pro plus 8 AMS HT, 24 filaments; X1/P1 printers: up to 4 AMS units [5] |
| Bambu AMS lite | A1 series; not compatible with X1 or P1 [7] | 1 unit, 4 colours [7][8] |
Slots, drying, RFID and price
The table compares the two flagship units with the official details each brand publishes [1][2][5].
| Item | Creality CFS | Bambu AMS 2 Pro |
|---|---|---|
| Listed US price | $299 (reference $319), out of stock on 30 October 2026 [1] | $229 (typical $299) [5] |
| Colours per unit | 4 [2] | Bambu states 16 colours with four AMS units on the P1S [6] |
| Drying | Sealed dry box with desiccant [2][10] | Active heated drying up to 65 °C with auto-venting [5] |
| Humidity readout | Real-time temperature and humidity display [11] | Temperature and humidity shown on printer, Bambu Studio and Handy [5] |
| RFID | Reads Creality RFID filament; printer reader on K2 Pro and K2 Plus only [3] | RFID sync, used to auto-match drying settings for Bambu filament [5] |
| Not supported | TPU, damp PVA and BVOH [2] | TPE, generic TPU, damp PVA/BVOH, Bambu PET-CF and TPU 95A, other CF/GF filaments [5] |
| Spool size | 197–202 mm diameter [2] | 197–202 mm diameter, 50–68 mm wide [5] |
| Power | From the printer via the 485 cable [2] | 24 V input; drying on A1/P1/X1 needs a Switching Adapter per unit [5] |
Drying: a real difference, with caveats
The AMS 2 Pro heats. Bambu lists 65 °C as the highest drying temperature but adds two caveats: that maximum is reached only above 25 °C ambient, and higher-temperature filaments such as ABS, ASA, PA and PC cannot be dried completely in it [5]. It also cannot dry on its own; it must be connected to a powered printer [5].
The CFS, by Creality's description, is a sealed dry box that uses desiccant to protect filament from moisture, and none of the Creality pages we read lists a heater [2][10]. Treat it as storage for dry spools, not a dryer for wet ones. The K1-series CFS-C also uses desiccant and shows temperature and humidity on a small LCD [4]. If your spools absorb moisture between uses, budget for a separate dryer with a CFS.
Purge waste: why multicolour costs filament, without invented figures
Bambu's wiki explains the mechanism clearly. On a single-nozzle printer, each colour change leaves old filament in the hotend, which must be flushed out before the new colour prints cleanly [9]. The flush volume depends on the colour pair: dark to light needs more than light to dark. A prime tower adds more material on top [9].
Bambu gives one worked example. Turning the same model upside down so that colour changes happened near the bottom cut the prime tower from 14.76 g to 9.05 g, about 40% less [9]. Neither brand publishes a per-change waste figure that would allow a fair head-to-head, and we will not invent one. The practical rule is the same on both: fewer colour changes per layer, and changes grouped low in the model, waste less.
Creality's CFS-C page describes an external route that collects purged filament outside the printer [4]. That makes cleanup tidier but does not reduce how much is purged.
Materials: neither is a TPU solution
Creality says the CFS does not support TPU and suggests the printer's standard spool holder instead [2]. Bambu lists generic TPU as unsupported in the AMS 2 Pro, with only its own "TPU for AMS" on the supported list [5]. The AMS lite FAQ warns against TPU, TPE, absorbent PVA and third-party fibre-reinforced filaments [7].
For carbon fibre, the AMS 2 Pro supports specific Bambu CF products and rules out other CF and GF filaments [5]. The CFS-C lists only Creality PLA types at present, with more promised through firmware [4]. If abrasive or flexible filaments are central to your work, plan to feed them from an external spool, whichever brand you choose.
Cost to grow to 16 colours
On a K2 Plus Combo, which already includes one CFS, three more units at the $299 listing add $897, though the standalone CFS was marked out of stock on 30 October 2026 [1]. On a P1S, Bambu says 16 colours takes four AMS units [6], and its AMS 2 Pro page counts the AMS 2 Pro as one of up to four AMS units on X1/P1 printers [5]. Starting from a P1S AMS 2 Pro Combo, three more units at $229 add $687 [5]. Non-combo X1/P1 printers also need a filament buffer, AMS hub, tube coupler and cable for the first unit [5]. These are sale-period prices; confirm before buying.
Most people never need 16 colours. Four slots cover a model with a few colours, or simple spool backup for long single-colour prints.
Who should pick which ecosystem
Lean Bambu if heated drying in the feeder matters. Lean Creality if you are already buying a K2-series printer, where the CFS is the native option, or a K1-series printer that only needs four colours. The A1 series with the AMS lite is a separate, cheaper path covered in our AMS lite guide.
- Pick the printer first; the multicolour unit follows it.
- Count the colours you really need per model.
- List any TPU, PVA or CF filaments; plan external feeding for them.
- Budget for a dryer if you choose a desiccant-only unit.
- Check which accessories your printer needs before adding a standalone unit.
Questions before you decide
Can I use a Creality CFS on a Bambu printer, or an AMS on a Creality printer?
Neither brand documents that. Creality lists only its own printers for the CFS and CFS-C, and Bambu lists only Bambu Lab printers for the AMS 2 Pro.
Does the CFS dry filament like the AMS 2 Pro?
No. Creality describes the CFS as a sealed dry box with desiccant. The AMS 2 Pro has active heated drying up to 65 °C, with limits that Bambu documents.
Which system wastes less filament?
Neither brand publishes comparable per-change purge figures. Bambu documents that waste depends on colour pairs and prime tower height, and that reorienting a model can cut prime tower material by about 40% in its example.
