Prusa MK4S to CORE One+ Conversion Kit, xLCD New

Turn your Original Prusa MK4S into the Prusa CORE One+ and take your 3D printing experience to the next level! This comprehensive conversion kit not only makes your printer faster, but also allows it to print larger models and perfectly process demanding materials like PCCF or nylon – without any warping. Everything you need for the conversion is included, so you end up with a fully enclosed CoreXY printer that leaves nothing to be desired.

Proven technology, new level

The Prusa CORE One+ is based on many proven components of the original MK4S - therefore, you can easily upgrade your existing printer and benefit from backward compatibility. Print sheets, hotends, nozzles, and other parts can be seamlessly reused!

► Note: Before purchasing the conversion kit, please check which xLCD electronics are installed in your printer – this is crucial for compatibility with the kit (see photo).

Space-saving and stylish

The all-steel exoskeleton of the Prusa CORE One+ is not only visually stunning, but also a masterpiece of stability and precision. At the same time, the printer is a true space saver: with a footprint 50% smaller than the MK4S, it still offers 30% more print volume. Thanks to its compact design, you can fit more printers in the same space – how about a print farm?

Nextruder quality

With the Prusa CORE One+, you can be sure your models will look exactly as you envisioned. The improved Nextruder with 360° cooling enables flawless printing, even with challenging 75° overhangs. Add to that the quality-oriented print profiles, developed in-house to guarantee maximum precision and dimensional accuracy - all while saving time and material.

Maximum filament flexibility

Whether PLA, PETG, or advanced technical materials, the CORE One+ delivers top quality. Thanks to its high-flow nozzle, input shaper, and over 200 optimised print profiles, it not only prints faster than ever before but also maintains the proven Prusa quality.

The compact print chamber has been cleverly optimised to prevent warping and effortlessly print even challenging materials like ASA, ABS, PC, and PA. Thanks to active temperature control and an automatic ventilation system, you can even print PLA perfectly with the door closed – a true all-rounder!

Perfect for tinkerers and creatives

The Prusa CORE One+ is a modder's paradise! Everything is screwed together, nothing is glued – meaning maximum freedom for your ideas. With a simple screwdriver, you can completely disassemble the printer and customise it to your liking.

If you're more interested in physical modifications, the printed parts of the printer offer you countless opportunities to let your creativity run wild!

Tip: Compared to the CORE One L, the CORE One+ combines high-quality hardware improvements with all firmware optimisations:

► Automatic top venting: The extruder now controls the top venting automatically: open for low-temperature materials such as PLA and PETG, closed for high-temperature filaments. This ensures an optimal thermal environment at all times, even without manual intervention.

► Flexible filaments? No problem: A newly designed filament inlet makes inserting flexible materials quick, easy and reliable.

► New bayonet spool holder: The redesigned spool holder supports different spool sizes and is already prepared for a direct feed drying box, for clean material handling and consistent results.

► Firmware & Performance out of the box: The CORE One+ comes with all software updates from the entire CORE One era. This means noticeably better print quality, optimised workflows, and exceptionally smooth operation right out of the box.

Other features:

• Open-source software and firmware,
• Supports multi-colour printing and is compatible with MMU3
• Doors can be opened a full 180°,
• Option to feed the filament from a spool hanging above the printer,
• Equipped with a LAN port and a detachable WLAN module,
• Seamless integration with Prusa Connect and Prusa App,
• Offline use is possible – the Wi-Fi module can simply be unplugged.
• Ideal for print farms,
• Versatile expansion possible with accessories (e.g. optional USB-C camera, GPIO hackerboard, advanced filtration system, etc.).
