The Bambu Lab H3C (professional) and Prusa Research CORE One+ (prosumer) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. Both are enclosed CoreXY printers with automatic calibration. The H3C costs $1,500 more and gets you 131% more build volume and a top speed of 1,400 mm/s (vs 600); the CORE One+ 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+, MK4S
Best for: Makers who want CoreXY speed and precision with Prusa's open-source ethos, community support, and long-term repairability — without Bambu's closed ecosystem.

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+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 209 days, so it is 44% of the way through — roughly 118 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+ has roughly 118 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+ lists at $999 and the H3C at $2,499 — $1,500 apart, so the H3C costs 150% more.
Per litre of build volume, that works out to $73 for the H3C versus $67 for the CORE One+ — the CORE One+ is the better value per litre as well.
This one is close on paper. If your parts fit within the CORE One+'s 250 × 220 × 270 mm, save the $1,500; if not, the H3C's 131% extra build volume earns its premium. The CORE One+ also brings extra engineering materials (ABS and ASA) and an open-source design.
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.
The CORE One+ matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.
Unlike Bambu's closed ecosystem, every component of the CORE One+ can be modified, repaired, or community-improved.
The CORE One+ (Gen 2) can be ordered with Prusa's INDX toolchanger in 4- or 8-tool versions, shipping from 15 October 2026. Each material gets its own nozzle, with about 12 seconds per material change and almost no purge waste. The MMU3 remains compatible as a 5-color add-on.
