The Prusa CORE One+ is a fully enclosed CoreXY printer with an all-steel exoskeleton, active chamber heating up to 55°C, and fully automatic calibration. With 200+ tested filament profiles ready out of the box, it delivers flawless prints with minimal effort, earning it “Best Enclosed 3D Printer of 2025” from All3DP and a Red Dot Award for design.
Flawless Precision
Perfect dimensional accuracy with Nextruder
The CORE One+ produces dimensionally accurate prints thanks to Prusa’s internally developed print profiles, which are optimized for quality and consistency. The upgraded Nextruder features 360° cooling that allows clean printing of overhangs up to 75°, reducing the need for supports and saving both time and material.
Maximum Speed
Fast Printing with Any Filament
The CORE One+ is built for high-speed printing without requiring specialized high-speed filaments. Whether you’re working with standard PLA and PETG or more advanced materials, the printer is designed to maintain impressive speeds while delivering consistent print quality.
Its CoreXY motion system, high-flow nozzle, Input Shaper, and factory-tuned profiles for more than 200 filaments work together to optimize printing speed and accuracy.
Get faster prints without sacrificing the detail, reliability, and quality you expect from your 3D printer.
