Large Format FDM for Serious Makers
Announced in August 2025, the Bambu Lab H2S is the entry point into Bambu’s H2 platform: a family of large-format, high-capability printers designed for makers who have outgrown the compact 256mm cube of the P-series and need something bigger, faster, and more capable.
At $1,249 the H2S is a meaningful price jump from the P2S. What you get for that jump is a 340 x 320 x 340mm build volume, a 65°C actively heated chamber, 350°C nozzle capability, and a platform designed for production-level printing. This is the machine for makers who print every day.

Why H2 Is a Different Category
The H2 series is not just a bigger P2S. The entire platform is built around different priorities.
65°C active chamber heating. Where the P2S heats to 50°C, the H2S heats to 65°C. This is the threshold that opens up serious engineering filaments: PA (nylon), PA-CF, PPA-CF, PPS. Materials used in functional mechanical parts, drone frames, and production tooling that demand high-temperature printing environments.
350°C nozzle. Most desktop printers max at 300°C. The 350°C ceiling allows the H2S to process high-performance filaments that simply cannot melt at lower temperatures.
HEPA and activated carbon filtration. At this tier of engineering filaments, air quality matters seriously. The H2S includes both HEPA particulate filtration and activated carbon for VOC absorption built into the enclosure.
30% faster than the X1C. At 600mm/s maximum print speed and with the larger build volume, the H2S is a genuine production machine. Print farms and Etsy sellers who run printers continuously find the H2S transforms their output capacity.
H2S vs H2D: Which to Choose
The H2S is the single-nozzle H2. The H2D is the dual-nozzle H2 and costs $500 more. The choice comes down to whether you need dual extrusion.
Choose the H2S if: You primarily print large single-material or AMS multi-color jobs. You want the largest possible H2 build volume (the H2S has 340mm depth vs the H2D’s 325mm). You do not need two materials printing simultaneously.
Choose the H2D if: You regularly need true dual-material printing — model plus soluble support, rigid plus flexible, or two engineering-grade materials in one print. The H2D’s dual nozzle enables cleaner support removal and genuine two-material workflows that the H2S simply cannot do.
Printing OreKo Models on the H2S
Using an H2S for OreKo deck boxes and miniatures is like using a sports car to commute. It absolutely works, it works excellently, but most hobbyists will not extract the machine’s full value from this catalog alone.
Where the H2S makes sense for OreKo-style printing is volume. If you want to run a full plate of deck box bodies and caps simultaneously, run the print overnight, and have it done by morning with zero intervention, the H2S’s larger build volume and production-grade reliability make that trivially easy. Etsy sellers and print-on-demand makers producing OreKo models for others will extract real value from this machine. Casual home makers probably will not justify the price.
Built for Makers Who Print Every Day
The H2S handles any filament, any model, any scale. Start with OreKo files on Cults3D.
