The Original Prusa CORE One+ assembled version is a fully enclosed 3D printer with CoreXY kinematics and active chamber temperature control up to 55 °C. It offers a 250x220x270 mm build volume, a full-metal steel exoskeleton, and an improved Nextruder with 360° cooling. Developed and manufactured in the Czech Republic, it is an ideal choice for beginners and professionals alike.

CoreXY kinematics for fast and precise printing

The CORE One uses CoreXY kinematics, which delivers higher print speed and motion accuracy than a classic bed-slinger design. Combined with Input Shaper technology and a high-flow nozzle, the CORE One can print any filament at full speed - not just special high-speed variants. The firmware dynamically compensates for resonances, so you get smooth surfaces without ringing even at high speeds.

Enclosed chamber with active temperature control

The fully enclosed chamber is actively heated up to 55 °C, making the CORE One an ideal machine for printing advanced materials. It handles ASA, ABS, PC, Nylon, and other technical filaments without warping. An automatic ventilation system also prevents chamber overheating when printing PLA - the printer sets the optimal temperature by itself, even with the doors fully closed.

Nextruder with 360° cooling

The improved Nextruder handles overhangs up to 75° without supports thanks to symmetrical 360° part cooling. Internally tuned print profiles for more than 200 materials ensure maximum dimensional accuracy. The high-flow nozzle enables high flow rates without loss of quality - the Nextruder is also backward compatible with nozzles from the MK4/S model.

Compact dimensions, large build volume

The CORE One takes up 50% less space than an MK4S in the Enclosure box, yet offers a 30% larger build volume - 250x220x270 mm. An ideal choice for a home workshop, office, or print farm. Prusa Research operates a farm with more than 600 printers, and the CORE One was designed precisely for efficient use of space in serial production.

Robust steel exoskeleton

The full-metal outer frame is an integral part of the construction, giving the printer exceptional rigidity and stability at high speeds. No parts are glued - everything can be disassembled with just a screwdriver, which makes maintenance, modifications, and long-term repairability easy. Prusa Research keeps spare parts in stock for many years after a model is released.

Plug and print - from unboxing to first print in 10 minutes

The assembled version of the CORE One+ is ready for immediate use. Just unbox it, perform a one-time calibration, and you can start printing. Automatic first layer calibration, filament detection, and advanced sensors ensure trouble-free operation. Start a print with a single click from PrusaSlicer, Printables.com, or the Prusa App mobile application.

Complete ecosystem: Prusa Connect, App, and Printables

The printer is equipped with a LAN port and a removable Wi-Fi module (setup via NFC). Prusa Connect enables secure remote management, and the Prusa App provides an ad-free mobile overview. Through Printables.com, you have access to hundreds of thousands of free models. Everything also works fully offline - firmware can be updated via USB as well.

Ready for MMU3 and multi-color printing

The CORE One is compatible with the MMU3 multi-material unit, which allows printing with up to five filaments at once from a single nozzle. The innovative retraction system and compact purge tower save material and keep the area around the printer clean. It's also a great way to use colorful PETG or PLA filaments.

Backward compatibility with MK4/S

If you own an MK4 or MK4S, you can reuse the print sheets, nozzles, and the entire hotend for the CORE One. Prusa Research also offers a conversion kit for an upgrade. You're investing in a platform that continues to evolve - firmware and hardware updates arrive even years after release.
