The Bambu Lab H3C and Prusa Research CORE One L+ are cross-brand rivals: both are professional-tier printers, listed $500 apart. Both are enclosed CoreXY printers with automatic calibration. The H3C costs $500 more and gets you a top speed of 1,400 mm/s (vs 500) and 9-slot multicolor; the CORE One L+ answers with extra engineering materials (ABS and ASA) and an open-source design.
First-generation product — recently released, still early days
Best for: Studios, engineers and power users who print many colours or materials per job, such as soluble supports, rigid-plus-TPU parts or CMYKW colour mixing, and want each material on its own dedicated tool rather than purging through a single nozzle.

🔧 Upgrade kit available — from CORE One L
Best for: Engineers and professional makers who need large-format enclosed printing with active chamber heating — and want Prusa's open-source ethos and long-term support over a closed-ecosystem competitor.

The H3C was released on Nov 3, 2026, 9 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
The CORE One L+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 279 days, so it is 33% of the way through — roughly 188 days before a successor would be due at that pace.
Both are early enough in their cycles that timing should not decide this one. The H3C launched 9 days ago and the CORE One L+ has roughly 188 days of runway on past cadence. Pick on features and price.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The CORE One L+ lists at $1,999 and the H3C at $2,499 — $500 apart, so the H3C costs 25% more.
Per litre of build volume, that works out to $73 for the H3C versus $67 for the CORE One L+ — the CORE One L+ is the better value per litre as well.
Our pick for most buyers is the H3C, for a top speed of 1,400 mm/s (vs 500) and 9-slot multicolor, plus a higher editor score (9.0 vs 8.6). Go for the CORE One L+ instead if you want to spend less — it is $500 cheaper ($1,999 vs $2,499).
How we judge timing and deals: read our methodology →
Swaptek keeps nine tools docked, loaded and pre-heated, each with its own filament path and heater. Bambu quotes 6-second material switches and very small purge volumes per swap, so multi-material prints waste far less filament than single-nozzle AMS printing.
Each tool can carry a different nozzle size or material. That makes it possible to print a 0.2 mm detail section, a 0.4 mm structural part and a soft 75A TPU section in one job.
The AMS 3H stores and feeds filament inside a sealed unit, and a built-in dryer handles moisture-sensitive PA, PC and TPU. Older AMS units can connect for up to 24 spools.
A large enclosed build volume with genuine active chamber heating — making the CORE One L+ reliable for ABS, ASA, PA, and PC across the full build plate.
All firmware, hardware designs, and slicing profiles are open source. Prusa backs the CORE One L+ with long-term parts availability and community support.
For institutional, government, and production customers, a dedicated Critical Infrastructure Edition is offered — Prusa's commitment to secure supply for professional users.
