NEW
The whole Prusa lineup just got upgraded
Better prints. Easier everyday use.
We focused on the everyday experience, with better-looking prints, faster preparation, easier maintenance, and fewer things you need to take care of yourself.
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.

Accessories to consider
CORE One+ works perfectly out of the box. Still, you may want to consider these accessories to level up your 3D printing game.
1080p Camera with Night Vision Function
Install an optional 1080p camera for remote print monitoring. The camera connects using a USB-C cable directly into the motherboard and requires an active Wi-Fi connection to function.
Advanced Filtration System
The optional Advanced Filtration System is useful when you print materials such as ASA and other materials that produce an increased number of ultra-fine particles and fumes during printing.
Additional nozzles, print sheets and filaments
Depending on what you want to print, you might consider adding a hardened nozzle (for abrasive engineering materials) or smaller nozzles for printing detailed models.
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 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.
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.
Prusa CORE One+ (Gen 2) Assembly kit
The best way to get to know your 3D printer

Right to Repair
Upgradability
Whenever it's even remotely possible, we offer our customers a clear and transparent upgrade path. When an improved model comes out, you can usually upgrade the printer you have at home.
100% Privacy: Offline Mode without Compromise
You don’t have to connect the printer to the network - not even once, and you can still enjoy the full experience without any drawbacks. The printer can be configured and operated offline, including slicing and installation of firmware updates. The Wi-Fi module can be easily unplugged for environments with the highest level of security. We believe that no matter whether you’re developing a new-generation space shuttle, or just printing toys for your kids, no organization should be interested in gathering information about your prints or your printer’s surroundings.
What's New in the CORE One+
- Automatic Top Vent Operation
- The printer now automatically opens the vent for low-temperature materials (PLA, PETG) and closes it for high-temp materials in a true set-and-forget fashion.
- Easy Flex Loading
- A redesigned filament insertion point makes feeding flexible filaments like TPU quick and simple. No more fighting with soft materials at the entry point.
- New Bayonet-Style Spoolholder
- Accommodates various spool sizes and is ready for a direct-feed drybox setup. Swap spools faster, use any brand without adapters.
- All Firmware Updates
- Every software improvement developed throughout the CORE One lifespan is included - better print profiles, smoother motion, improved sensors. Most refined version from day one.
There is a real risk that data on prints, design models, or production processes could be transmitted to servers beyond the user’s control, including to the territory of the PRC.

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.
Common Questions
I've never printed before. Is this printer too advanced for me?
Not at all - it's actually one of the easiest ways to start. The assembled CORE One+ does automatic calibration, so there's no leveling or tuning. PrusaSlicer has default profiles that work perfectly for most models: just open a file and click print. Over a million free designs on Printables.com mean you don't need to know 3D modeling. And if you ever get stuck, our support team is available 24/7 via live chat. Many of our happiest customers started with zero experience.
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?
No. PrusaSlicer is free and you can download it from our website. It comes with 200+ print profiles (pre-made settings). A standard computer (Windows, macOS, or Linux) is all you need to prepare print files. Or you can use the Prusa app and do everything from your smartphone. The printer connects via Wi-Fi, Ethernet, or USB. No subscriptions, no recurring costs.
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)
The CORE One+ (Gen 2) refines the same proven platform with new GT1.5 belts for smoother-looking surfaces, an integrated nozzle wiper for cleaner starts, redesigned heatbed mounting that significantly shortens print preparation, and a snap-on top panel for easier maintenance. It also benefits from our latest firmware improvements focused on making everyday printing simpler and more automatic.
Is the firmware really open-source?
Yes, fully. The firmware source code is published on GitHub under an open license. The CAD files for the mechanical design are also published. You can modify, compile, and flash your own firmware builds. We've been doing this since our very first printer in 2012 - open source is part of how Prusa works.
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?
Fair question. With CORE One+ you get open-source firmware, free software with no subscriptions, spare parts stocked for years, and 24/7 support from our team members - 3D printing enthusiasts themselves. The printer is built to be repaired with a screwdriver. Everything is included in the price: no recurring fees, no premium tiers. We have developed and manufactured our 3D printers in the heart of Europe since 2012, and we have recently expanded our operation to Delaware, USA. Every time a new model came out, we offered clear and transparent upgrade paths - something you don't see anywhere else in consumer hardware.
