Prusa CORE One L

The Prusa CORE One L is the logical evolution of the popular CORE One 3D printer - taking everything you loved about its predecessor and giving you even more of it! More space, more power, more convenience!

With a huge build volume of 300 x 300 x 330 mm, an actively heated chamber and the innovative AC convection heating bed, the CORE One L offers professional print quality in a compact, easy-to-maintain housing!

Comparison CORE One vs. CORE One L:

Large size, perfect control - 300 x 300 x 330 mm

With twice as much build volume (63%!) as the Core One, the CORE One L gives you plenty of room for big models, functional parts, and complex prototypes without any warping or adhesion issues.

The rigid steel-aluminium frame ensures maximum precision and minimal vibration.

New AC convection heating bed

The solid aluminium heating bed guarantees even heat distribution over the entire printing surface. Two integrated fans create a convection effect that heats up the chamber quickly and ensures stable temperatures of up to 60 °C - perfect for demanding materials such as ASA, ABS, PC or nylon.

Precision at the highest level

Thanks to the proven Nextruder system with 360° cooling and finely tuned printing profiles, models can be printed with maximum dimensional accuracy and excellent surface quality - without any reworking.

Fast, strong, reliable, versatile and compatible

The robust CoreXY kinematics, a high-flow hotend and the integrated input shaper enable high printing speeds with consistent quality - for over 200 supported filament types.

A dedicated switch on the filament sensor makes switching to Flex Mode effortless, allowing flexible materials to be processed more easily and reliably. A second sensor in the print head monitors material flow in real time.

Ready to use in 5 minutes

Unpack, click in the display, switch on - and off you go! The Core One L calibrates itself automatically and creates the optimum print conditions all by itself. No manual tuning, no test runs - just start printing!

Perfect for tinkerers and creatives

Like its predecessor, the Prusa CORE One L is a dream come true for modders! Every part is screwed, not glued - giving you full freedom to customise, modify, and rebuild to your heart’s content.

Prefer to do physical modifications? The printer’s printed parts open up endless opportunities for creativity and experimentation.
