The Bambu Lab H2S and Prusa Research XL+ are both professional-tier printers, but the XL+ costs 1.8× as much — so the question is what the extra money buys. Both are CoreXY printers with automatic calibration. The XL+ costs $1,050 more and gets you an open-source design and 26% more build volume; the H2S answers with a top speed of 1,000 mm/s (vs 500) and an enclosed chamber (with PPS on its materials list).
Mid-cycle — watch for announcements before buying
Best for: Professional makers and studios who need Bambu's largest enclosed build volume for high-throughput production, engineering materials, and optional AMS multicolor — without the complexity of dual-nozzle printing.

The H2S was released on Aug 26, 2025, 443 days ago. Its previous release cycle ran about 730 days, so it is 61% of the way through — roughly 287 days before a successor would be due at that pace.
The XL+ was released on Aug 13, 2026, 91 days ago. Prusa Research has already announced what comes next: XL Pick & Place Toolhead (Late 2026). Because Prusa Research sells upgrade kits for this line, owners can move up without replacing the whole printer.
Neither is a clear buy-now on timing, so watch for announcements before committing. The XL+ is further along (65% vs 61%).
Cycle and deal status as of November 12, 2026. See the launch calendar →
The H2S lists at $1,249 and the XL+ at $2,299 — $1,050 apart, so the XL+ costs 84% more.
Per litre of build volume, that works out to $34 for the H2S versus $49 for the XL+ — the H2S is the better value per litre as well.
If you are buying before Dec 5, 2026, the active sale tips value toward the H2S.
Our pick for most buyers is the H2S, for a lower price ($1,050 less) and a top speed of 1,000 mm/s (vs 500), plus a higher editor score (9.1 vs 8.7). Go for the XL+ instead if you want an open-source printer you can modify and repair yourself — the H2S is not open source. The H2S is also in a sale window right now (Bambu Black Friday 2026, until Dec 5, 2026).
How we judge timing and deals: read our methodology →
The H2S offers more than twice the print volume of the X2D. At 1000 mm/s it is also among Bambu's fastest printers, 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.
Unlike filament-switching AMS/MMU systems, the XL physically swaps print heads. Each material has its own nozzle, eliminating purge towers entirely and enabling true multi-material prints.
One of the largest build volumes available in a CoreXY printer at this price point — suited for large props, architectural models, and batch production.
Every component is documented, parts are stocked for years, and the community has developed hundreds of modifications and improvements.
