Bambu Lab A1 vs Prusa Research CORE One L+
The Bambu Lab A1 (entry) and Prusa Research CORE One L+ (professional) 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. The CORE One L+ costs $1,700 more and gets you an enclosed chamber (with ASA, PA, PA-CF and PC on its materials list) and 77% more build volume; the A1 answers with 4-slot multicolor.
💰Bambu Lab A1 is $1,700 cheaper (85% less)
📐Prusa Research CORE One L+ has 77% more build volume
🏠Only Prusa Research CORE One L+ has an enclosure — and it adds ASA, PA, PA-CF, PC to the materials list
🎨Only Bambu Lab A1 supports multicolor printing (4 slots)
⚠️ Ecosystem lock-in warning: Bambu and Prusa are not interchangeable ecosystems. Bambu's AMS system is proprietary — multicolor filaments, cloud features, and software are tightly coupled. Prusa's MMU3 is open source. Switching ecosystems later means replacing filament profiles, software presets, and accessories. Choose based on your long-term workflow, not just the current specs.

Who Should Choose Each
Choose the Bambu Lab A1 if…
- you want our higher-rated printer — 9.1 vs 8.6 out of 10
- you want to spend less — it is $1,700 cheaper ($299 vs $1,999)
- you want multicolor prints — it supports 4 slots, while the CORE One L+ is single-color
- your prints fit within 256 × 256 × 256 mm — then the CORE One L+'s extra build volume is money you do not need to spend
- you are buying before Dec 1, 2026 — it is in Bambu Black Friday 2026 right now
Choose the Prusa Research CORE One L+ if…
- you want to print ASA, PA, PA-CF and PC — it is enclosed and lists them, while the A1 is open-frame
- you print large parts — its 300 × 300 × 330 mm build volume holds 77% more than the A1's 256 × 256 × 256 mm
- you are buying now — it is the safer pick on timing (early in cycle, vs overdue for refresh for the A1)
- you want an open-source printer you can modify and repair yourself — the A1 is not open source
- you are coming from the CORE One L — Prusa Research sells an upgrade kit to CORE One L+ spec
Our Take
This one is close on paper. If you will stick to materials both printers list (PLA, PETG, TPU and ABS), save the $1,700; if you want ASA, PA, PA-CF and PC, the CORE One L+'s enclosure earns its premium. The A1 also brings 4-slot multicolor.
