PRUSA CORE ONE L

This professional 3D printer is a highly versatile solution for any type of project. With a large 300×300×330 mm build volume, an actively heated chamber up to 60 °C, and a new AC convection heated bed, it delivers warp-free printing even with demanding technical materials. It is ideal for businesses, professional workshops, shared makerspaces, and design studios. Fully compatible with any slicer and usable entirely offline, it offers complete freedom without the limitations of closed ecosystems.

When you buy a Prusa, you become the actual owner of your 3D printer — not just of a license to operate it.

The steel exoskeleton frame and smart engineering choices ensure exceptional rigidity, stability, and outstanding print quality. With intuitive software and true one-click printing, you can start your first print just minutes after unboxing. Access to a large library of free 3D models ensures a constant stream of inspiration and ready-to-print projects.

The CORE One L is far more than an enlarged version of the CORE One. Beyond increasing size, it features structural and functional improvements that make large-format printing simple, efficient, and highly reliable.

The combination of a strong steel frame and lightweight aluminum panels results in a surprisingly rigid yet manageable structure. The external dimensions are only about 10% larger than the smaller CORE One, while the print volume is doubled.

The standard heated bed has been redesigned into a powerful AC convection system with active airflow circulation for perfectly even thermal distribution. The printer includes a removable 1080p camera with night vision, two nozzles, fully automatic chamber temperature control, an improved path for flexible filaments, and much more.

This machine is perfect for everything from ambitious hobby projects to specialized industrial production.

Think Big. Print Big.
The 300 × 300 × 330 mm build volume allows you to create large functional parts, production tools, architectural prototypes, cosplay helmets, and more — all in a single piece. The upgraded heated bed provides ideal heat distribution for flawless edge-to-edge printing.

New AC Convection Heated Bed
The massive solid-aluminum AC bed provides perfectly even heating and eliminates cold spots entirely. Two fans beneath the bed create a convection airflow that quickly brings the chamber to 60 °C, making advanced-material printing far easier and more reliable.

Unbox and Print!
From unboxing to first print takes only a few minutes. All calibrations are handled automatically, and the printer optimizes the internal environment by itself. Simply prepare a model using your preferred slicer and start printing.

“Switch On and Forget” Machine
The expanded build volume supports both large models and multiple simultaneous prints. Ideal for overnight jobs and small-batch production runs. The integrated night-vision camera enables remote print monitoring at any time.

Impeccable Precision
Thanks to professionally tuned print profiles, every model prints true to the original design with excellent dimensional accuracy. The Nextruder with 360° cooling ensures flawless performance even on overhangs up to 75°.

Superior Surface Quality
With the latest slicer improvements and optimized profiles, surfaces are smoother than ever — greatly reduced VFA and minimal vertical banding. Prints come off the bed ready to use as final products.

Maximum Speed Without Gimmicks
The CORE One series delivers top-tier speed with any filament, not just “high-speed” specialty materials. The robust CoreXY motion system, high-flow nozzle, Input Shaper, and factory-tuned profiles ensure fast prints without sacrificing quality.

Effortless Printing With Advanced Materials
The actively heated chamber makes printing ASA, ABS, PC, PA (nylon), and other engineering polymers easy and highly reliable — no warping, no cracking, no lifted corners.

Flexible Filament Management
A dedicated feeding mode opens a wider and less restrictive filament path for flexible materials by temporarily disabling the side sensor. A second sensor inside the print head continues to monitor filament presence.

Rigid Steel Exoskeleton
The fully steel frame provides exceptional stability and durability, while still allowing easy maintenance. Every component can be replaced with basic workshop tools, and spare parts remain available for years.

All-in-One Package
CORE One L includes an accelerometer, guided belt-tension setup, and complete factory calibration. Two nozzles are provided (high-flow and abrasion-resistant) to cover the full range of printing needs.

Optimized for Print Farms and Industrial Use
Designed for demanding production environments, the printer ensures minimal downtime and consistent reliability even in large-scale workflows.

No Vendor Lock-In
The printer works fully offline with no required accounts or cloud dependency. It is truly yours to use however you want, for as long as you want.
