Prusa CORE One Conversion kit contains all parts you need to transform your Original Prusa MK4Sinto the fully enclosed CoreXY 3D printer, the Prusa CORE One. This kit is compatible with the MK4S only!
The silver PSU is not compatible with the conversion kit.
Transform your Original Prusa MK4S into thebrand new, fully enclosed CoreXY 3D printerand upgrade your printing experience. Once you’re finished with the assembly, your new printer is going to be not only faster, but it will alsotake up less space, print larger models and tackle evendemanding filaments like PCCF or Nylon without warping. In the Conversion Kit, you will find everything you need to perform the entire process and end up with thePrusa CORE One without any compromise.
The Prusa CORE One utilizesmany proven parts from the Original Prusa MK4S. This is why it is possible to convert your existing 3D printer into the new Prusa CORE One, and also why we can offer outstanding backwards compatibility. You can easilyreuse your current print sheets, hotends, nozzles, and many other parts.
xLCD Info
Before you order the upgrade, please check which xLCD electronics your printer came with. This is important for correct compatibility with the upgrade. Depending on the selected options, we can send you additional components to ensure compatibility with the upgrade.
The top image is of theNEWERversion of the xLCD. If you have this version please choose the "MK4S -> CORE One (for newer version of xLCD)" option in the menu on the right.
The bottom image is of theOLDERversion of the xLCD. If you have this version please choose the "MK4S -> CORE One (for older version of xLCD)" option in the menu on the right.
The CORE One is a 3D printing workhorse engineered in the proven Prusa tradition. Designed with a "made to last" philosophy and made from premium materials, the CORE One offers exceptional reliability with minimal maintenance. The enclosed chamber, capable of reaching up to 55 °C, features active temperature control for high-quality printing across a wide range of materials from PLA and PETG (even with the door closed) to more demanding materials like ASA, PC, or Nylon.
Plug and Print!
10 minutes from unpacking to first print
Unpack the printer, perform a one-time calibration, and you’re ready to go. Equipped withadvanced sensors for hassle-free printing, the CORE One is a true “start and forget” machine. Simply start your print and let the printer handle the rest, fromfully automatic first-layer calibrationto pausing the print and sending a notification if the filament runs out.
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 enablesflawless 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 Core XY kinematics, high-flow nozzle, Input Shaper andfactory-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 Onetakes up 50% less spacethan the MK4S inside an enclosure, yet itdelivers 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. Thisallows 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. Theautomatic ventilation systemand 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. Theenclosure 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.
Create colourful 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 onlyreduces the wasted filamentbut also deposits all the waste to a single, tidy block.
Built to Last
