Prusa CORE One Kit

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.

Seamless Workflow

Everything you need under one roof

When you buy the Prusa CORE One, you’re getting a full experience – a huge free
3D model library, an easy to use software, remote management, native mobile app,
premium quality materials… everything is ready for your convenience!



 

Printables.com

You don’t have to be a designer to use a 3D printer! Our database of hundreds of thousands
of free 3D models is just a click away. Printables.com is actively developed and
ever-growing, so go ahead and get amazing prints by talented creators and even
official printable accessories for a variety of popular products thanks to Printables
Brands. You can send models from Printables.com to PrusaSlicer in a single click!



 

PrusaSlicer

The best slicer out there! An open-source, feature-rich, frequently updated tool 
that contains everything you need to export the perfect print files for your 3D printer.
All official printer and material profiles (over 200 in total) are created and tested
in-house to ensure the best possible printing experience! And you don’t have to
be a pro to use it, the default profiles let you slice most models with one click.
PrusaSlicer is based on Slic3r by Alessandro Ranellucci.



 

Prusa Connect

Our internally-developed highly secure remote print management software is here
to make your printing experience a breeze. It’s fully integrated with PrusaSlicer and
enables you to quickly send your print files to the CORE One, schedule tasks, and
monitor your machine remotely. It’s an incredibly powerful tool with new features being
added all the time.



 

Prusa App

The new streamlined Prusa App gives you a complete overview of your printer no matter
where you are. With no ads, points or other bloatware, the app is easy to navigate and use.
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.

Network Connectivity

Prusa CORE One is equipped with a LAN port and a detachable Wi-Fi module (Wi-Fi can
be set up a with an NFC tap). It integrates seamlessly with both Prusa Connect and
Prusa App, so you always have a complete overview of your printer. However, the printer 
can be operated in a full offline mode without any compromise. You can even flash
the firmware from a USB drive.
 

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!

 

Chamber Camera

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. 
The camera is scheduled to be ready in the same timeframe as the Prusa CORE One,
so stay tuned – we will give you the option to edit your order and add the camera in
case you order the printer before the camera becomes available.

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.

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. The filtration is scheduled to be ready in the
same timeframe as the Prusa CORE One, so stay tuned – we will give you the option
to edit your order and add the filtration in case you order the printer before the filtration
becomes available.
 

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.

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 i
nformation about your prints or your printer’s surroundings. This is why our printers
an be found in top companies, universities and research institutions around the world.
