Prusa CORE One L

Think big. Print big.

Prusa CORE One L builds on the award‑winning CORE One model and adds double the build volume of 300×300×330 mm in a compact body. Thanks to active heat circulation in the chamber and the new AC convection bed, it distributes heat evenly across the entire surface – from edge to edge without “cold corners” and without warping of parts.

Key advantages for your production

• Enclosed and heated chamber up to 60 °C for trouble‑free printing of ASA/ABS, PC, PA etc. (with optional filtration).
• AC convection heated bed (up to 120 °C) with two fans for fast chamber heating and perfect temperature homogeneity.
• Nextruder (Direct Drive) with 10:1 gearing, 360° cooling and automatic first layer calibration via Load Cell.
• Two nozzles in the package: 0,4 mm High-Flow (brass CHT) + 0,4 mm durable for abrasive materials.
• Robust CoreXY kinematics in a steel exoskeleton for top‑class surface quality and dimensional accuracy.
• Start & Forget: the printer is factory‑assembled and pre‑calibrated; from unboxing to first print in just a few minutes.
• Operation without cloud: full functionality even completely offline; removable Wi‑Fi module, Ethernet and printing from USB/LAN.
• Integrated 1080p camera with night vision for remote monitoring (installation optional).
• Open ecosystem: no vendor lock‑ins – any materials, slicers and offline workflows.

Who it is suitable for

• Manufacturing and prototyping: jigs, covers, holders or functional parts from engineering materials.
• Schools and research: safe enclosed space, teaching with multiple materials and reliable operation.
• Makers & design: large models, cosplay helmets or architectural models in one go.

Software and management

• Open‑source PrusaSlicer and the new EasyPrint for quick setup.
• Prusa Connect and Prusa App for print management, notifications and monitoring (can be used even without cloud).

Materials

Basic: PLA, PETG, Flex, PVA, PC, PP, CPE, PVB. With the advanced filtration system (optional accessory): ABS, ASA, HIPS, PA (Nylon) and other materials for enclosed chambers.
