Anycubic Kobra S1 Max vs Bambu Lab A1
The Anycubic Kobra S1 Max (professional) and Bambu Lab A1 (entry) 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 Kobra S1 Max costs $500 more and gets you an enclosed chamber (with ASA, PA, PA-CF, PC and PET-CF on its materials list) and 156% more build volume.
💰Bambu Lab A1 is $500 cheaper (63% less)
📐Anycubic Kobra S1 Max has 156% more build volume
⚡Anycubic Kobra S1 Max tops out at 600 mm/s vs 500 mm/s

Timing: When to Buy
The Kobra S1 Max was released on Nov 25, 2025, 352 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
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.

Who Should Choose Each
Choose the Anycubic Kobra S1 Max if…
- you want to print ASA, PA, PA-CF, PC and PET-CF — it is enclosed and lists them, while the A1 is open-frame
- you print large parts — its 350 × 350 × 350 mm build volume holds 156% more than the A1's 256 × 256 × 256 mm
- you are buying now — it is the safer pick on timing (recently launched, vs overdue for refresh for the A1)
- you want PLA-CF, PETG-CF and PVA — listed for the Kobra S1 Max but not the A1
- print speed matters — it is rated for 600 mm/s against 500 mm/s
Choose the Bambu Lab A1 if…
- you want our higher-rated printer — 9.1 vs 8.1 out of 10
- you want to spend less — it is $500 cheaper ($299 vs $799)
- your prints fit within 256 × 256 × 256 mm — then the Kobra S1 Max's extra build volume is money you do not need to spend
Our Take
Our pick for most buyers is the Kobra S1 Max, for an enclosed chamber (with ASA, PA, PA-CF, PC and PET-CF on its materials list) and 156% more build volume, plus better buy-now timing. Go for the A1 instead if you want to spend less — it is $500 cheaper ($299 vs $799).

Why buy each?
Anycubic Kobra S1 Max
350×350×350 mm large-format build volumeOne of the largest enclosed build volumes in the prosumer/professional tier — suited for large engineering parts, architectural models, and batch production.
65°C active chamber heating at scaleMaintaining 65°C across a 350×350 mm chamber is a meaningful technical achievement — ensuring consistent results for ABS, ASA, and PA across the full build plate.
Anycubic ecosystem continuityThe S1 Max extends the Kobra ecosystem into the large-format enclosed segment, enabling Anycubic users to scale up without switching brands.
Bambu Lab A1
AMS Lite multicolorThe A1 Combo includes the AMS Lite for 4-color filament switching — the same system used on the A1 Mini and A2L.
256×256×256 mm build volumeRoughly 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.
Bambu ecosystem integrationWorks with Bambu Studio, Bambu Handy app, and the full Bambu filament ecosystem including multi-material profiles.
