Original Prusa Core ONE L (Assembled Printer)

This is the versatile 3D printer for every kind of project. Thanks to the print volume of 300300330mm, an actively heated chamber up to 60C, and the new AC convection heatbed, it is perfect for effortless, warp-free printing of demanding materials. Its the best tool for every kind of business, home workshop, shared makerspaces, or design studios – all in one package. You can integrate it into our open ecosystem while remaining completely free from the limitations of a walled garden. Print in top quality with any material, use any slicer, and run the printer completely offline if you choose.The exoskeleton frame and smart design choices ensure maximum firmness and robustness, which translates directly into outstanding print quality. With intuitive software and one-click printing, users can begin printing their first model within minutes after unpacking. Plus, access to over one million free 3D models on Printables.com guarantees a constant supply of exciting projects. You will always have something to print!CORE One – Doubled!Huge print volume, active heat circulation, and more!The CORE One L is much more than just a larger CORE One. We didn’t just scale it up; we took everything that worked great and added features for effortless large-format printing.For the body, we have chosen an effective combination of a solid steel frame and aluminum panels to create a lightened version of our proven exoskeleton design. And the results are compelling: the machines outside dimensions are only 10% larger than the CORE One, yet it maintains the same weight, and the print volume is doubled!The standard heatbed has been replaced with our new AC convection heatbed with active air circulation for flawless heat distribution in the chamber. The printer comes with a detachable 1080p camera with night vision, two nozzles in the package, fully automatic chamber temperature management, easier FLEX filament feeding, and much more.This machine covers everything: from ambitious hobby projects to highly demanding manufacturing!Think Big. Print Big.Because now everything fits!The 300300330 mm print volume (CORE Ones volume doubled) is the sweet spot for any kind of project. It lets you print large functional parts, production fixtures, architectural models, full-size cosplay helmets,and other massive objects all in one piece. And the best part? The new heatbed has the best heat distribution possible thanks to the materials used, so you can effortlessly print from edge to edge.New AC Heatbed with Convection HeatingNo cold corners, fast heat upThe new massive AC heatbed is made of a thick block of aluminum for the best possible heat distribution. This results in perfectly uniform heat distribution from edge to edge – no cold spots, no cold corners. You can place your model anywhere in the print area without worrying about lifted corners or warping. Two fans on the underside of the heatbed create a convection effect – they bring cold air in and blast it across the massive heated surface to quickly bring the chamber all the way up to 60 C.Flawless PrecisionWhat You Design is What You GetYou can be sure that with our internally developed, quality-focused print profiles, your models will turn out exactly how they were designed, with perfect dimensional accuracy as proven by CT scans. CORE One L utilizes the proven Nextruder with 360 cooling for flawless printing of 75 overhangs, saving both time and material.Maximum Speed without a CatchFast with every filament, not just specialized onesDont limit your projects to a small selection of specialized high-speed filaments. Use any PLA, PETG, or many advanced materials. The CORE One series represents our fastest printers yet: robust CoreXY kinematics, high-flow nozzle, Input Shaper, factory-tuned print profiles for 200+ filaments – its all there. However, we never sacrifice print quality to chase speed records. The prints are always solid, durable, and wont crumble in your hand.Robust Steel ExoskeletonA design that works and looks the PartPrusa CORE One is built as an all-steel exoskeleton. The enclosure is an integral part of the printer, providing it with outstanding stability and rigidity. However, maintenance is still simple, and if you need to replace a worn part in a couple of years, its a complete no-brainer. You can take everything apart with a screwdriver. As usual with us, we hold parts in stock for yearsCreate colorful 3D objects!Ready for the MMU3*The CORE One L is compatible with the MMU3, the add-on for the fastest single-nozzle printing with up to five filaments at the same time. You can create beautiful, colorful objects, and you wont have to throw half of your filaments away or constantly clean the surroundings of your printer. Our solution uses an innovative retraction technique and a compact wipe tower to manage filament changes.This not onlyreduces the wasted filamentbut also deposits all the waste to a single, tidy block.*In upcoming MMU upgrade.Make it your own!Designed for moddersNo parts of the printer are glued together,everything can be taken apart with a set of screwdriversand theres plenty of room for mods, creativity and customization so go ahead and make the CORE One L your own! Print magnetic holders, organizers, or just plain fun stuff to make your printer stand out.Our software and firmware areopen-source and you can grab the source codes atGitHub.com.This allows you to modify the code, come up with your own improvements and tweaks.We often cooperate with our community members on new features,and you can become one of them! Or if you dont want to dig into the code, you can try your hand at modifying the printed parts of the printer. There are dozens of opportunities for all sorts of projects!Technical ParametersMeasurementsBuild Volume300 x 300 x 330 mm | 11.8 x 11.8 x 12.99 inFilament diameter1.75 mmLayer height0.05-0.30 mmPrinter dimensions21,9 kg, 469521635 mm; 18.520.525 in (WDH)ElectronicsMainboardCustom 32-bit xBuddy electronics with STM32Stepper DriversTrinamic 2130Stepper motors1.8 Stepper motorsExtruderExtruderNextruder, Direct Drive, E3D V6 compatible (with adapter)Extruder electronicsCustom breakout board for connecting fans, thermistors and other parts.Filament pathAluminum heatsink, all-metal hotendDrive systemNextruder Planetary Gear System, 10:1 gearbox ratioCooling fanHigh-performance turbine, 360 cooling systemNozzleHigh-flow Prusa Nozzle brass CHT – 0.4 mm + Abrasive-Resistant 0.4mm nozzle in the boxMax. operating temperatureMax nozzle temperature290 C / 554 FMax heatbed temperature120 C / 248 FMax chamber temperature60 C / 140 FControlsLCD screen3.5 graphic 65k color screenTouch controlYesFirmware update interfaceUSB drive, Prusa Connect, Prusa Mobile AppPrusa Connect supportYesPrusa App for iOS and Android supportYesQuick-Swap nozzle systemYesLightingYesAccessoriesInternal cameraIncluded in the box, installation optionalMMU3 supportYes.MMU3 (available Jan 2026)Advanced Filtration Systemoptional addonGPIO Board compatibilityYesAccelerometer compatibilityYes, built-inConnectivityEthernet connectionYesOther connectivityNFC receiverSensorsFilament SensorYes (2 sensors)Loadcell sensorYesThermistors5 high-precision thermistors (genuine Semitec)Fan motors monitoringYesDoor sensorYesPrintingPrint mediumUSB drive / LAN / internet via Prusa Connect or mobile Prusa AppPrint surfaceMagnetic heatbed with removable PEI spring steel sheetsFirst layer calibrationFully automatic (thanks to the Load Cell sensor)Bed calibrationAutomatic, Mesh Bed Leveling (only on print area)Input shaperYesSupported materialsPLA, PETG, Flex, PVA, PC, PP, CPE, PVB and when using the optional Advanced Filtration System ABS, ASA, HIPS, PAPhase SteppingYesDocumentsCore ONe L – Declaration of conformity
