Bambu A2L Teaser: What the Dual-Nozzle Patent Tells Us About Bambu Labs Next Move

The Teaser

Bambu Lab quietly published a teaser page at bambulab.com/en/a2l with a June 1 launch date. No specs, no images, just a countdown. But the patent filings tell a different story.

What the Patent Reveals

Patent CN120096089A, filed in late 2025, describes a dual-nozzle system with independent calibration. Unlike traditional dual-nozzle printers that share a single heater block, Bambu design uses two completely separate hotends with individual thermal management.

The key innovation is the calibration method: instead of relying on mechanical alignment, the system uses machine vision to detect and compensate for nozzle height differences in real-time. This means no manual calibration, no paper-thickness adjustments, and no failed first layers due to uneven nozzles.

The A2L: Extra Large A-Series

Industry sources suggest the A2L will be an extra-large format printer in Bambu Lab A-series lineup. Expected build volume: 350x350x400mm or larger, making it competitive with the Creality K2 Plus (350x350x350mm).

Expected Features:

• Dual independent hotends with vision-based calibration
• Heated chamber for engineering materials
• AMS 2 Pro compatibility
• AI-powered print monitoring
• Full Bambu ecosystem integration

Why Dual Nozzles Now

Bambu Lab has been perfecting single-nozzle AMS technology for years. The move to dual nozzles makes sense as a way to expand material capabilities - you can print with two different materials simultaneously without the waste of filament switching.

The real advantage: one nozzle can be dedicated to support material (like PVA or HIPS) while the other handles the primary model. No purging, no waste, no waiting.

Market Positioning

At an expected price of $1,200-$1,500, the A2L would sit between the P2S ($799) and X1 Carbon ($1,599). It would directly compete with the Creality K2 Plus and offer a more affordable entry into dual-material printing.

What to Watch For

The June 1 launch will likely reveal:

• Exact build volume and pricing
• Whether it uses the same AMS 2 Pro system
• Chamber heating capabilities
• Software support for dual-nozzle workflows

If Bambu delivers on the patent promises, the A2L could be the most compelling dual-material printer for under $1,500. The vision-based calibration alone would be a game-changer for reliability.
