Filament for the Bambu Lab A1 mini
The A1 mini takes the same AMS lite as the A1, but its bed stops at 80 °C rather than 100 °C. That single difference rules out the materials that need a hot plate, so the shopping list is shorter than its bigger sibling.

Every material, and where it goes
| Material | Nozzle | Bed | On the A1 mini | Why |
|---|---|---|---|---|
| ABA | 250–270 °C | 80–100 °C | Not on this machine | Open frame. ABA cracks and lifts on parts larger than a palm without a heated chamber. |

| ASA | 250–270 °C | 90–110 °C | Not on this machine | Needs a 90–110 °C bed; the A1 mini reaches 80 °C. |
| CF | 260–280 °C | 100–110 °C | Not on this machine | Needs a 100–110 °C bed; the A1 mini reaches 80 °C. |

On flexible material, Bambu Lab's own wording: “TPU that can be used with AMS lite: 77D, 55D, or higher hardness. TPU that cannot be used with AMS lite: 95A, 85A, 83A, 80A, or lower hardness.” Source
Worth knowing before you order
- The 80 °C bed is the binding constraint. PCTG and PC ask for 100–110 °C and will not stick reliably below it.
- Same 40–68 mm width and 53–58 mm hub window as the A1. Our spool is 65 mm wide with a 54 mm hub.
- 3 kg and 5 kg spools do not fit the AMS lite. Use an external holder or re-spool onto an empty 1 kg spool.
Profiles, not guesswork
The settings hub identifies generated starting values, target machines and unsupported material mappings. A preset is not validation on this printer; review the target and calibrate temperature, flow and retraction before a production part.
Shipped from the US
Stock, destination charges and shipment timing are confirmed before payment. The published contiguous-US offer applies above $35; see the shipping policy for conditions. Unopened-spool returns use the 30-day policy. Any 4 spools take 12% off, mixed however you like.
Start a mixed orderBambu Lab A1 mini filament questions
Do FilamentBay spools fit the Bambu Lab A1 mini?
Yes. The A1 mini uses the AMS lite, which Bambu Lab publishes as taking spools 40–68 mm wide with a 53–58 mm inner diameter. Our 1 kg spool measures 65 × 200 mm with a 54 mm hub, in injection-moulded plastic rather than cardboard.
Can I print flexible TPU on the A1 mini?
From the AMS lite, only the Shore D grade. Bambu Lab's AMS lite documentation says "TPU that can be used with AMS lite: 77D, 55D, or higher hardness", which covers our 72D but excludes 85A through 98A. Print the softer grades from the external spool holder.
What is the hottest bed the A1 mini reaches?
80 °C, with a 300 °C nozzle, per Bambu Lab's published specification. That is what rules out ABA, ABS, ASA, CF, ESD, PC, PCTG on this machine.
Can I print ABS on the A1 mini?
Not reliably. The frame is open, so anything larger than a palm tends to crack or lift. Use PETG for tough parts on this machine, or PCTG if the bed reaches its temperature.
Do you have Bambu Studio profiles?
See the settings hub for each material and format. Some files are starting presets with a different target machine, some are manual worksheets, and unconfirmed polymer mappings are withdrawn. No universal import or printer validation is claimed.
Do 3 kg and 5 kg spools work on the A1 mini?
Not in the AMS lite: they are wider and larger than the published window. Print them from an external holder, or re-spool onto an empty 1 kg spool.
