This is a versatile 3D printer for all your projects. With a build volume of 300x300x330mm, an active heated chamber up to 60°C, and a new AC convection heatbed, it effortlessly prints challenging materials while minimizing warping. Suitable for a wide range of environments, from business use, home workshops, shared maker spaces, to design studios. It integrates into an open ecosystem, free from the constraints of closed-off environments. You can print high-quality models with various materials, use any slicer, and even operate completely offline if needed. Choosing Prusa means owning the machine itself, not just a license to use it.
The exoskeleton frame and thoughtful design ensure high rigidity and robustness, directly translating into excellent print quality. With intuitive software and one-click printing, you can start printing your first model just minutes after unboxing. Plus, with over a million free 3D models available on Printables.com, you'll always find something to print for your next project. See the announcement on our blog!Start printing now, upgrade to INDX later
Start with the CORE One L and begin printing right away. When you want to enhance its capabilities further, you can easily install the INDX upgrade.
The INDX upgrade is an innovative tool-changing system developed in collaboration with Bondtech. It allows you to combine up to 8 colors or 8 types of materials in a single print, with automatic switching in seconds and near-zero waste.
Traditional multi-material printing involved long tool-change times, significant filament waste, and frequent adjustments to ensure stable use of different materials. INDX eliminates these issues. Non-contact magnetic induction heating provides almost instantaneous tool changes with minimal oozing and stringing, while the self-adjusting Dynamic Extruder automatically optimizes tension for each filament. The INDX is not yet available for purchase but will be soon. Register for updates to stay informed. 
CORE One doubled!
Large build volume, active thermal circulation, and more features
The CORE One L is more than just a bigger CORE One. It's not a simple scale-up; it builds on existing strengths while adding features to make large-scale printing easier. The body features an effective combination of a robust steel frame and aluminum panels, making the proven exoskeleton design lighter. As a result, its external dimensions are only 10% larger than the CORE One, but it weighs the same and offers twice the build volume.
The standard heatbed has been upgraded to a new AC convection heatbed with active air circulation, providing more uniform heat distribution within the chamber. Additionally, it boasts numerous features such as a removable 1080p night vision camera, two included nozzles, fully automatic chamber temperature management, and easier FLEX filament feeding.
This single unit covers a wide range of uses, from ambitious hobby projects to demanding manufacturing applications.
