The Bambu Lab A2L and Prusa Research CORE One+ are both prosumer-tier printers, but the CORE One+ costs 2.1× as much — so the question is what the extra money buys. The CORE One+ costs $530 more and gets you an enclosed chamber (with ASA, PA and PC on its materials list) and an open-source design; the A2L answers with 131% more build volume.
First-generation product — recently released, still early days
Best for: Makers who want the largest possible open-frame build volume on a budget — large cosplay, terrain, and functional parts — with optional multicolor via AMS Lite.

The A2L was released on Jun 1, 2026, 164 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
The CORE One+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 209 days, so it is 44% of the way through — roughly 118 days before a successor would be due at that pace.
Both are early enough in their cycles that timing should not decide this one. The A2L launched 164 days ago and the CORE One+ has roughly 118 days of runway on past cadence. Pick on features and price.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The A2L lists at $469 and the CORE One+ at $999 — $530 apart, so the CORE One+ costs 113% more.
Per litre of build volume, that works out to $14 for the A2L versus $67 for the CORE One+ — the A2L is both cheaper and roomier, so it wins on value outright.
If you are buying before Dec 5, 2026, the active sale tips value toward the A2L.
This one is close on paper. If you will stick to materials both printers list (PLA, PETG, TPU and ABS), save the $530; if you want ASA, PA and PC, the CORE One+'s enclosure earns its premium. The A2L also brings 131% more build volume.
How we judge timing and deals: read our methodology →
Bambu's largest bed-slinger build volume, big enough to print full-size helmets and large props in a single piece rather than in glued sections.
The A2L stores several calibration sets at different heights up the Z axis to keep the faint vertical banding of tall bed-slinger prints under control.
An add-on blade-cutting and pen module extends the A2L beyond printing for sticker cutting and plotting workflows.
The CORE One+ matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.
Unlike Bambu's closed ecosystem, every component of the CORE One+ can be modified, repaired, or community-improved.
The CORE One+ (Gen 2) can be ordered with Prusa's INDX toolchanger in 4- or 8-tool versions, shipping from 15 October 2026. Each material gets its own nozzle, with about 12 seconds per material change and almost no purge waste. The MMU3 remains compatible as a 5-color add-on.
