Prusa CORE One+ - FDM 3D printer or kit

The CORE One+ from the renowned company Prusa is presented as a robust and highly reliable platform for additive manufacturing, designed to operate with minimal maintenance requirements. Its design follows the "built to last" product philosophy, reflected in the use of high-quality components that ensure stable long-term performance. The combination of its actively heated enclosed chamber, capable of reaching 55 ºC, and the CoreXY architecture enables fast printing without compromising dimensional accuracy.

The Prusa CORE One+ incorporates a direct evolution aimed at professional applications, integrating hardware improvements derived from the CORE One L along with all firmware optimizations developed throughout the CORE One lifecycle. This combination of enhancements provides more consistent print quality, smoother handling, and a much more autonomous work environment. Its automatic top ventilation opening and closing system adjusts airflow according to the material type—opening for PLA or PETG and closing for higher-temperature polymers—thus maintaining stable thermal conditions. Additionally, the new filament insertion point is optimized to facilitate loading of flexible materials, reducing errors and speeding up changes. The bayonet-style spool holder supports reels of various sizes and is designed to work directly with a drybox. These improvements help reduce setup time, enhance reliability, and increase efficiency in production environments.

Despite maintaining a compact desktop format, the CORE One+ offers a build volume of 250×220×270 mm, making it suitable for multiple professional applications, including printer farm operation. The steel exoskeleton forming its main structure increases overall rigidity and allows quick disassembly with basic tools, facilitating maintenance, cleaning, or component upgrades.

The CORE One+ encourages ecosystem expansion thanks to its fully open software and firmware, allowing function customization, modifications, and development of specific configurations according to production needs. Additionally, there are multiple optional accessories: USB camera, accelerometer, GPIO board for advanced users, advanced air filtration system, and dryboxes for filament storage. For those already using the MK4/S, there is notable compatibility with consumables and common parts—nozzles, print sheets, and hotends—facilitating gradual integration or scaling of the machine fleet without complications.

Intuitive "plug-and-print" design

The CORE One+ "plug-and-print" approach allows for quick start after a single initial calibration. Daily operation is straightforward thanks to its 3.5″ color touchscreen, which centralizes relevant information and simplifies navigation through menus and settings.

Its set of advanced sensors ensures stable operation even during extended print sessions. It includes filament sensor, load cell, power-loss recovery, and high-precision thermistors. The RGB status bar and internal lighting facilitate visual process monitoring, contributing to a more autonomous and reliable user experience.

Exceptional material compatibility

The CORE One+ guarantees very wide material compatibility, covering standard PLA and PETG as well as engineering-grade polymers like ASA, PC, and Nylon. This makes it a versatile tool for both prototyping and functional production.

The active heated chamber maintains stable thermal conditions, essential for materials sensitive to shrinkage or warping. Its magnetic heated bed, capable of reaching 120 ºC, includes removable PEI-coated steel sheets, providing better adhesion, easy removal, and uniform thermal control throughout the process.

Advanced extrusion technology

With its CoreXY kinematics and a vibration-optimized construction, the CORE One+ can achieve high printing speeds while maintaining high precision. The printer has pre-calibrated profiles for over 200 materials, allowing a wide range of filaments to be used without complex adjustments. Key features include high-flow nozzles, 0.9° stepper motors on X and Y axes, and Input Shaper technology, which compensates vibrations to improve surface finish even at high speeds.

The CORE One+ features the direct-drive Nextruder, integrating a 10:1 planetary gear system to improve traction and extrusion precision. Its aluminum heatsink, all-metal hotend, and high-flow brass nozzle (0.4 mm) provide excellent results even for complex parts. The 360° cooling allows handling challenging geometries—like steep overhangs—consistently, while the quick-change nozzle system facilitates maintenance and increases operational flexibility.

Multimaterial printing with MMU3

To expand creative and technical capabilities, the CORE One+ is fully compatible with the MMU3 multimaterial unit, enabling the use of up to five filaments simultaneously. This allows multicolor parts, material combinations, and advanced applications.

The optimized retraction mechanism and compact purge tower work together to minimize waste, improve process efficiency, and keep filament changes under control. This not only increases visual accuracy in multimaterial prints but also promotes more responsible material usage.

Seamless workflow integration

The CORE One+ easily integrates into professional and advanced user environments, providing direct access to the complete Prusa ecosystem. Associated tools include the Printables library, PrusaSlicer slicing software, the Prusa Connect remote management platform, and the Prusa mobile app, providing a complete and cohesive workflow.
