A1 Mini
The Bambu Lab A1 Mini is a FDM 3D printer released in 2023 by Bambu Lab, with a build volume of 180³ mm and MSRP of €299. Compatible with AMS lite (4 slots). Claimed maximum speed: 500 mm/s.

Our take on the A1 Mini
The A1 mini is probably the simplest way to start 3D printing in colour: a small printer (180 × 180 × 180 mm build volume) with automatic load-cell calibration, a quick-swap nozzle up to 300 °C and support for the 4-spool AMS lite. It's for people short on space who want the machine to just work.
In the catalogue, only the Creality K2 SE offers multicolour for less. Against it, the A1 mini leans on Bambu Lab's ecosystem (Bambu Studio, the app and MakerWorld), while the K2 SE gives a bit more volume. If the size falls short, its bigger sibling, the A1, goes up to 256 mm per side with the same philosophy.
Its limits are clear: the volume won't take large parts, the bed reaches 80 °C (plenty for PLA, PETG and TPU, but ABS is out) and it's open-frame. The AMS lite also sits outside the printer and takes its own space on the desk. We have a longer analysis against its rivals.

What materials can the A1 Mini print?
This comes from four facts on its spec sheet: the nozzle reaches 300 °C, the bed 80 °C, and the machine is open-frame with a direct-drive extruder. Those four facts decide most of the list: nozzle temperature sets the ceiling on what you can melt, the bed decides whether the first layer sticks, the enclosure keeps large parts from warping, and the extruder type rules flexibles. We don't test the machine — this is guidance derived from verified data, not a guarantee.
In short: it prints PLA, PETG, TPU (flexible) without a fight, and it can reach ABS, ASA, Nylon (PA), Policarbonato (PC) with conditions — the detail for each is below.
| Material | Prints it? | Why |
|---|---|---|
| PLA | Yes | Yes. PLA has no special needs: any FDM printer like the A1 Mini prints it out of the box. |
| PETG | Yes | Yes. With a nozzle up to 300 °C and a bed up to 80 °C it comfortably meets PETG's needs. |
| TPU (flexible) | Yes | Yes. It has a direct-drive extruder, ideal for flexibles; prints TPU well (go slow). |
| ABS | With caveats | With caveats. It reaches 300 °C, but it's open-frame: ABS can warp and ventilation is advised. Doable in a draft-free spot or by adding an enclosure. |
| ASA | With caveats | With caveats. It reaches 300 °C, but it's open-frame: ASA can warp and ventilation is advised. Doable in a draft-free spot or by adding an enclosure. |
| Nylon (PA) | With caveats | With caveats. It reaches 300 °C but is open-frame; Nylon warps in drafts and absorbs moisture. Enclosure + drying almost mandatory. For carbon-fibre variants, use a hardened-steel nozzle. |
| Policarbonato (PC) | With caveats | With caveats. It has the temperature (300 °C) but is open-frame; PC warps badly without an enclosure. Only with one added. For carbon-fibre variants, use a hardened-steel nozzle. |
