The H2S offers 220% the print volume of the X1C. At 1000 mm/s it is also Bambu's fastest printer, making it the top choice for high-throughput professional production.
The enclosed chamber with active heating handles the full engineering filament spectrum — ABS, ASA, PA, PA-CF, PC, and PPS — with consistent results across the full build plate.
The H2S supports up to 12 AMS units (4 AMS 2 Pro + 8 AMS HT), enabling 24-filament printing for large-format multicolor production.
One of the largest enclosed build volumes in the prosumer/professional tier — suited for large engineering parts, architectural models, and batch production.
Maintaining 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.
The S1 Max extends the Kobra ecosystem into the large-format enclosed segment, enabling Anycubic users to scale up without switching brands.
