NEW
The whole Prusa lineup just got upgraded
Better prints. Easier everyday use.
The revised platform focuses on shorter preparation, cleaner print starts, surface finish and easier maintenance access.
What’s new with 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.
Faster print starts
The redesigned heatbed mounting removes the separate “Absorbing heat” wait for materials using bed temperatures up to 85 °C. Higher-temperature materials benefit from a shorter wait as well.
Smoother-looking surfaces
New GT1.5 belts make unwanted repeating patterns finer and harder to notice, especially on large, smooth surfaces where even subtle artifacts can stand out.
Cleaner print starts
The integrated nozzle wiper cleans filament from the nozzle before printing, helping keep loose strands and small blobs away from the print surface.

Reviews and awards
Uncle Jessy
"This is by far the best Prusa 3D printer experience that I've ever had so far."
The Real Sam Prentice
The print quality is absolutely divine! I've tested this across a range of filaments, and the results have been consistently impressive."
Captain Creativity
When it came to quality, the reigning champion of quality still goes to Prusa, and it’s no different with the CORE One.
3D Printing Doctor
"This machine is extremely fast - 20% faster than the MK4S - thanks to the CoreXY motion, 360° cooling, and the high-flow nozzle. (...) I am excited to continue printing more stuff with this machine."
Six engineering choices that set the CORE One+ apart.
CoreXY uses two fixed motors in the corners that pull on a long, continuous loop of belts to move a tool head. Because the heavy motors are fixed in place, the gantry is incredibly light, allowing for blazing fast speeds and outstanding precision.
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.
Nextruder: Precision at Every Layer
Nextruder uses a load-cell sensor to measure force at the nozzle, allowing the nozzle itself to probe the surface. The printhead also provides cooling around the part and replaceable nozzles. Check the nozzle sizes and compatibility supported by the selected model.
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
Published CAD and firmware repositories allow inspection and modification under their respective licences. The printer does not depend on a cloud connection for normal offline printing.
The key to successful prints
Active Chamber Temperature Control
Engineering materials warp when they cool unevenly - corners lift, layers separate, prints fail. CORE One+ prevents this with a compact chamber that hits up to 55 °C, creating a stable environment. And the best thing? While other printers need you to open the door for printing low-temp materials (like PLA), you can keep the CORE One+ door closed thanks to smart chamber ventilation.
Your Printer, Your Rules
Experience a printing platform designed with transparency, repairability, and your creative freedom in mind. You own your 3D printer, not just a license to use it.
Any Filament, Any Brand
CORE One+ works with any standard 1.75 mm filament. Use Prusament for tested quality or pick your favorite brand. PrusaSlicer includes over 200 ready-made profiles, and you can always create your own for new materials.
Connection is Optional
Print via USB drive or your local network - no internet connection required. Optional Prusa Connect adds remote monitoring and print farm management. You don't have to connect the printer to the internet; not even once.
Open-Source Files
The firmware source code is on GitHub and CAD files are published at Printables.com. You can inspect, modify, or build your own version. Tinkering is optional, but if you want to mod your printer, you have all the resources.
Free Software, No Tiers
PrusaSlicer, EasyPrint, Prusa Connect, the Prusa App, and every firmware update - included with the printer and free. No forced ads, no hidden subscription tiers.
Right to Repair
Upgradability
Prusa offers model-specific upgrade paths where available. Check the supported starting model and supplied components before choosing an upgrade kit.

Making 3D printers since 2012
From the heart of Europe to the entire world
Prusa Research is a 3D printer manufacturer based in Central Europe - in Prague, Czech Republic. It is now a team of over 1,000 people with a brand new factory opened in Delaware, USA. But it started as a one-man project. In 2010, Josef Průša designed an open-source printer that hobbyists could actually afford. It caught on. Years later, the company is still in Prague, still independently owned, and still making printers the same way - designed in-house, built to last, and shared openly with the community that helped build them. A lot has changed in 3D printing. Not everything needs to.
CORE One+ vs MK4S vs CORE One L
All three share the same Prusa ecosystem, firmware, and slicer. The differences are in size, enclosure, and target use case.

Frequently asked questionsAnswers to common questions about this product.
I've never printed before. Is this printer too advanced for me?
The assembled CORE One+ can be a practical first printer because it automates calibration and has supplied slicing profiles. Start with a suitable model and material, follow the setup guide and contact Fabinity if you need help choosing or getting started.
Is CORE One+ good for beginners?
Yes. Despite being a fully-featured 3D printer, CORE One+ is designed for simplicity. Automatic bed leveling, factory-tuned print profiles, and a 10-minute setup mean you can go from unboxing to printing without prior experience. The printer handles the complexity - you just choose what to print. If you're brand new to 3D printing, the assembled version is the easiest start.
Do I need any other software or tools?
PrusaSlicer is free and runs on Windows, macOS and Linux. It includes printer and material profiles for preparing files. Prusa's mobile tools offer another preparation route. Check the selected printer's connectivity and workflow requirements in the technical details.
Should I buy the kit or assembled?
Both deliver the identical printer with the same warranty and performance. The kit is usually a full weekend project and teaches you every part of the machine - useful if you enjoy building things and want to understand your printer inside out. The assembled version is factory-calibrated and prints within 10 minutes of unboxing/installation. Neither is better; it depends on what you enjoy.
What materials need the enclosure?
ABS, ASA, polycarbonate (PC), and nylon (PA) all benefit significantly from an enclosed, heated chamber. These materials shrink as they cool, and uneven cooling causes warping. The active chamber keeps temperatures consistent, preventing failures. PLA and PETG don't need an enclosure but print fine inside one thanks to automatic ventilation.
What are the differences between the CORE One+ and CORE One+ (Gen 2)
Gen 2 adds GT1.5 belts, an integrated nozzle wiper, a revised heatbed mounting and a snap-on top panel. These changes target surface finish, cleaner starts, preparation time and maintenance access, alongside firmware improvements.
Is the firmware really open-source?
The firmware and mechanical CAD files are published under their applicable licences. You can inspect the sources and, where the licence permits, modify and build your own versions.
Can I add multi-material later?
Yes - that's by design. MMU3 (Multi Material Upgrade 3) adds 5-filament printing and is compatible now. INDX, an 8-tool passive toolchanger built specifically for CORE One+, is on the way. You don't need to plan for these upgrades today, but the printer is ready for them when you are. Buy what you need now, expand later.
Why is Prusa more expensive than some other 3D printers?
CORE One+ combines free slicing software, published firmware sources and a serviceable mechanical design. Fabinity adds UK advice and support. Check the available upgrade and replacement-part options for your particular model.
