Original Prusa CORE One+ Gen 2 Printer with Canadian ETL Safety Certification

What's new with the CORE One+ Gen 2: The second generation keeps the same CORE One platform and adds several practical improvements: less waiting before a print starts, cleaner starts, smoother-looking surfaces, and easier access for maintenance. Firmware updates also continue to make everyday operation simpler.

Significant Features:

Fully Enclosed CoreXY Architecture 

The advanced CoreXY motion system moves the lightweight printing head instead of the heavy base, allowing for much higher speeds without losing quality. Input Shaper firmware compensates for vibration at high speeds.

Active Chamber with Smart Ventilation

The printer's enclosed chamber heats up to 55 °C. The system monitors temperatures at all times and adjusts automatically to create the best environment for any material you choose. Optional HEPA filtration integrates directly into the enclosure for offices and schools.

Precision at Every Layer

Nextruder is our next-gen print head featuring a precise Load Cell sensor that measures force at the nozzle tip - the nozzle itself becomes the probe. Because it is physical, it cannot be confused like optical sensors. Plus, 360-degree cooling means steep overhangs print cleanly without supports and nozzles (0.25 mm to 0.8 mm) are swappable in seconds without tools.

Robust Steel Exoskeleton

All-steel exoskeleton — the enclosure is structural, not an accessory. Exceptional rigidity at high speeds. Nothing is glued. Everything comes apart with a screwdriver. Designed for modders and tinkerers — replacement parts stocked for years.

Compact Footprint, Large Volume

50% less desk space than an MK4S inside an enclosure, yet 30% more print volume (250 × 220 × 270 mm). That efficiency matters whether you're fitting one printer on a desk or 600 into a print farm — which is exactly what Prusa Research does at their own facility.

Open-Source Hardware & Firmware

CAD files are published. Firmware source code is on GitHub. You can inspect, modify, or compile your own version. No locked bootloaders, no cloud dependency. We've been shipping open-source printers since 2012.
