The Bambu Lab A1 (entry) and Snapmaker U1 (prosumer) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. Both are open-frame printers with 4-slot multicolor, a 500 mm/s rated top speed and automatic calibration. The U1 costs $600 more and gets you an open-source design and 17% more build volume; the A1 answers with extra engineering materials (ABS).
Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Makers who want large prints and multicolor capability without an enclosure — ideal for PLA, PETG, and flexible materials.
Full details →First-generation product — recently released, still early days
Best for: Multicolor and multi-material hobbyists who want a true tool changer (four separate hotends, soluble supports, TPU and PLA in one print) for well under $1,000, and tinkerers who value Klipper-based firmware they can inspect and modify.

The A1 was released on Oct 19, 2023, 1,120 days ago. Its previous release cycle ran about 365 days; it is now 755 days past that point and no successor has been announced.
The U1 was released on Apr 10, 2026, 216 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
On timing alone, the U1 is the safer buy right now — it launched only 216 days ago, while the A1 is 755 days past its ~365-day cycle with no successor announced.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The A1 lists at $299 and the U1 at $899 — $600 apart, so the U1 costs 201% more.
Per litre of build volume, that works out to $18 for the A1 versus $46 for the U1 — the A1 is the better value per litre as well.
With both in sale windows, this is a good moment to buy either — compare the live sale prices before you decide.
Our pick for most buyers is the A1, for a lower price ($600 less) and extra engineering materials (ABS), plus a higher editor score (9.1 vs 8.4). Go for the U1 instead if you are buying now — it is the safer pick on timing (recently launched, vs overdue for refresh for the A1). One caveat: the A1 is 755 days past its ~365-day cycle with no successor announced, so check the launch calendar before you buy.
How we judge timing and deals: read our methodology →
The A1 Combo includes the AMS Lite for 4-color filament switching — the same system used on the A1 Mini and A2L.
Roughly 2.9 times the volume of the A1 Mini — great for terrain, cosplay props, and functional parts. The A2L is the step up if you need a larger bed-slinger.
Works with Bambu Studio, Bambu Handy app, and the full Bambu filament ecosystem including multi-material profiles.
Each filament has its own preheated hotend, and swaps take about 5 seconds. Multicolor prints skip the purge tower and filament waste of single-nozzle switching systems.
Separate hotends mean PLA with PVA or breakaway supports, or rigid PLA with TPU, in one print. Single-nozzle multicolor systems handle these combinations poorly.
Snapmaker has published its Klipper, Moonraker and Fluidd forks on GitHub, and Snapmaker Orca is built on Orca Slicer. There is already an active community firmware project. RFID filament recognition stays proprietary.
