Flawless Precision

Outstanding print quality thanks to the Nextruder

You can be sure that with our internally developed, quality-focused print profiles, your models will turn out exactly the way they were designed, with perfect dimensional accuracy. CORE One+ takes advantage of the upgraded Nextruder with 360° cooling that enables flawless printing of 75° overhangs, saving both time and material.

Maximum Speed without a catch

The CORE One+ is fast with every filament, not just specialized ones

Don’t limit your projects with a small selection of specialized “high-speed” filaments. Use any PLA, PETG or any of the advanced materials. While the CORE One+ is our fastest printer yet thanks to its robust CoreXY kinematics, high-flow nozzle, Input Shaper and factory-tuned print profiles for 200+ filaments, it never sacrifices quality for quicker print times.

Compact Footprint, Large Volume

The perfect fit for any home, workplace or print farm

The Prusa CORE One+ takes up 50% less space than the MK4S inside an enclosure, yet it delivers an impressive 30% increase in print volume. Space efficiency matters - even for us! With a massive 3D print farm of over 600 machines, the CORE One+'s compact footprint and optimized design let us fit even more printers into the same space and boost our production.

The Best Solution for Advanced Materials

Print durable functional models easily and without warping!

The chamber is as compact as possible, with a cleverly designed recess on each side to minimize its volume. This allows the chamber to quickly reach higher temperatures (up to 55°C), enabling you to print ASA, ABS, PC, PA (Nylons), and other advanced materials smoothly, without warping. The automatic ventilation system and active temperature control enable flawless printing of PLA - even with the door completely closed!

Robust Steel Exoskeleton

A design that works and looks the Part

Prusa CORE One+ is built as an all-steel exoskeleton. The enclosure is an integral part of the printer, providing it with outstanding stability and rigidity. However, maintenance is still simple, and if you need to replace a worn part in a couple of years, it’s a complete no-brainer. You can take everything apart with a screwdriver. As usual with us, we hold parts in stock for years.

Reviews and Awards

This is just about the best 3D printer you can get right now.

This machine is extremely fast—20% faster than the MK4S—thanks to Core XY motion, 360° cooling, and the high-flow nozzle. (…) I am excited to continue printing more stuff with this machine.

This is by far the best Prusa 3D printer experience that I've ever had so far.

The 3D printing world wouldn’t be as remarkable without Prusa and their open-source software, community spirit, and the strong community they’ve built over the years.

As you might expect, the print quality is absolutely divine! I’ve tested this across a range of filaments, and the results have been consistently impressive.

Prusa CORE One marked a significant leap forward in the CoreXY market, with TechRadar calling it “by far the most advanced and functional printer of this type on the market at present.” Recognized for its excellent build and professional-grade features, it delivers consistently reliable performance with top speed, accuracy, and versatility – earning it the title of “Best Enclosed 3D Printer of 2025” by All3DP. With a Red Dot Award to its name, it also proves that functionality can go hand-in-hand with standout design.

The app also has full Printables integration, so you can send ready-made G-codes directly into your printer without the need to slice them!

Prusament

We were not satisfied with the quality of filaments on the market, so we started manufacturing our own! Prusament offers top-class manufacturing precision, perfect color consistency and a wide range of materials from PLA to PCCF. Every Prusament material has an in-house tested profile in PrusaSlicer.

Create colorful 3D objects!

Ready for the MMU3

 

The CORE One+ is compatible with the MMU3, the add-on for the fastest single-nozzle printing with up to five filaments at the same time. You can create beautiful, colorful objects, and you won’t have to throw half of your filaments away or constantly clean the surroundings of your printer. Our solution uses an innovative retraction technique and a compact wipe tower to manage filament changes. This not only reduces the wasted filament but also deposits all the waste to a single, tidy block.

 

Make it your own!

Designed for modders

 

No parts of the printer are glued together, everything can be taken apart with a set of screwdrivers and there’s plenty of room for mods, creativity and customization – so go ahead and make the CORE One+ your own! Print magnetic holders, organizers, or just plain fun stuff to make your printer stand out.

Our software and firmware are open-source and you can grab the source codes at GitHub.com. This allows you to modify the code, come up with your own improvements and tweaks. We often cooperate with our community members on new features, and you can become one of them! Or if you don’t want to dig into the code, you can try your hand at modifying the printed parts of the printer. There are dozens of opportunities for all sorts of projects!

Expand it with accessories!

 

You can expand the CORE One+ with useful accessories. We offer an optional USB-C camera, and you can calibrate the Input Shaper profiles on modded printers with an optional accelerometer. Or play with the GPIO hackerboard, an accessory for enthusiasts that enables you to control external devices with G-Code commands. We're also preparing two different types of filtration, a drybox, and more - stay tuned!

 

 

You can install an optional high-resolution camera add-on into the CORE One+'s chamber for remote print monitoring. The camera connects using a USB-C cable directly into the motherboard and it requires an active Wi-Fi connection to function. Find more about the chamber camera for the Prusa CORE One+.

.

GPIO Hackerboard

The GPIO module is an optional add-on for advanced users (basic programming / soldering skills required). It extends functionality of the printer by allowing you to control and receive input from external devices using GPIO pins and G-code commands, so you can, e.g., control LEDs or remote triggers for DSLR cameras. Find more about the GPIO Hackerboard.

Advanced Filtration System

Studies have shown that most of the commonly used 3D printing materials should be safe, but we wanted to take this a step further. 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. Fewer particles and less odor in the air are always better. Find more about the Advanced Filtration System for the Prusa CORE One+.

Ready for the Future

With Exceptional Backwards Compatibility

When you buy the CORE One+, you’re investing into a platform that will continue to grow over time, rather than something that you’ll have to replace in a year or two. Prusa printers are well known for their exceptional reliability, durability and long life cycle. We offer excellent post-launch support with regular firmware and even hardware updates to expand your printer’s capabilities even years after launch. And when a new machine comes out, we publish an upgrade kit.

When new tech comes out, it’s usually exciting but it can also be a little inconvenient due to changes. You may need a new charger or a different phone case because the camera has moved. Not so with the CORE One! If you already own the MK4/S, you can reuse many accessories, such as print sheets, nozzles, and hotends. The CORE One uses many proven MK4S parts, which is why we also offer a convenient conversion kit.

 

Optimized for print farms

Boost your production with Prusa CORE One

 

We run a massive print farm with over 600 of our 3D printers producing parts for new 3D printers, so we know what it takes to run such a massive operation. We designed the Prusa CORE One+ so it fits right in – compact dimensions, doors that open in full 180°, possibility to feed the filament from a spool hanging above the printer, simple maintenance, maximum reliability, easy printing of advanced materials… it’s the perfect machine for mass production!

100% Privacy: Offline Mode without Compromise

You don’t have to connect the CORE One+ 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.
