Prusa CORE One L+ Single-Toolhead Enclosed 3D Printer

Original Prusa CORE One L+ Single-Toolhead 3D Printer | 300×300×330 mm Heated Chamber, Air Filter Ready

Think big. Print bigger. The Original Prusa CORE One L+ is the large-format enclosed CoreXY printer built for shops that are done cutting models apart and gluing them back together. You get a 300 × 300 × 330 mm build volume — about 29.7 liters, roughly double the CORE One+ — inside an actively heated 60 °C chamber, with plug-and-print setup and more than 200 validated material profiles. Unpack it, press Print, and the part on the bed is meant to be the finished product, not a prototype you have to hide the seams on.

This is the L+ generation of Prusa’s proven CORE One L platform. Compared with the original CORE One L, the L+ adds an integrated nozzle wiper for cleaner print starts, new GT1.5 belts for smoother surfaces, and the latest firmware refinements. It ships assembled, factory-tested, and pre-calibrated. First print is typically about five minutes after unboxing.

Built for large parts and engineering materials

Enclosed CoreXY kinematics with Input Shaper and Phase Stepping keep layers clean at speed, with travel up to 500 mm/s. The Nextruder direct-drive extruder uses a 10:1 planetary gearbox and an all-metal hotend. A 0.4 mm Prusa brass high-flow CHT nozzle ships installed for throughput; a 0.4 mm abrasive-resistant nozzle is in the box for carbon- and glass-filled filaments. Nozzles swap without tools. Maximum nozzle temperature is 290 °C, or up to 400 °C with the optional HT hotend for PEKK-CF, PPS-CF, PPSU, and PPA-CF.

The all-aluminum dual-loop AC heatbed holds temperature evenly across the large plate — within about 2 °C across most of the surface — up to 120 °C. LoadCell first-layer calibration and mesh leveling measure the real nozzle-to-sheet distance automatically. Automatic chamber vents open for PLA and PETG and close for high-temp materials, so large ASA, ABS, PC, and nylon parts stay flat instead of warping at the corners.

Open materials policy: any brand of 1.75 mm filament, no chips, no lock-in, no subscriptions. Ready out of the box for PLA, PETG, flex, PVA, PC, PP, CPE, and PVB. With the optional Advanced Filtration System, add ABS, ASA, HIPS, PA, and other technical filaments that need cleaner air as well as heat.

Air filter option: Advanced Filtration System

The CORE One L+ is fully enclosed from the factory. Add the official Advanced Filtration System when you print materials that release more ultra-fine particles and fumes:

• HEPA filter at 99.9% efficiency plus activated carbon
• High-pressure blower integrated with the printer firmware
• Cuts UFPs, VOCs, and odor on ABS, ASA, nylon, and similar
• Controlled from the printer menu during and after a print
• Filter life rated around 600 hours; replacement is straightforward
• Can also be ducted into HVAC or shop extraction for production use
• Sold separately and compatible with the CORE One family, including CORE One L+

You do not need the air filter for everyday PLA and PETG. Add it for engineering filaments, shared workspaces, and longer unattended runs where air quality matters.

Ready on day one, serviceable for years

Ships assembled. Connectivity is Ethernet, NFC, and Wi-Fi, with a physically removable Wi-Fi module for fully offline or high-security setups. A 1080p night-vision chamber camera is included and can be detached. Prusa Connect and the Prusa App are optional. USB printing works with no cloud account. Firmware is open source. The steel-and-aluminum frame is user-serviceable with a screwdriver — nothing glued, no proprietary locks. Spare parts are intended to stay available for years. Designed and manufactured in the EU.

The CORE One L+ is a single-tool Nextruder machine. Start there for large enclosed single-material work. An INDX toolchanging upgrade is planned later if you need multiple colors or materials in one job with near-zero purge waste.

Who the CORE One L+ is for

• Workshops that need one-piece parts up to 300 × 300 × 330 mm without moving up to the XL+ toolchanger
• Product design, fixtures, architecture, healthcare models, and cosplay
• Shops printing ASA, ABS, PC, nylon, and composites in a 60 °C heated chamber
• Teams that want an enclosed, offline-capable production printer with an optional HEPA + carbon air filter

If you need 360 mm cubic volume and a multi-head toolchanger now, look at the Prusa XL+. If you want enclosed CoreXY speed, a 60 °C chamber, and double the CORE One+ volume on a compact bench, the CORE One L+ is the right machine.

Highlights

• 300 × 300 × 330 mm enclosed CoreXY 3D printer — about 2× the CORE One+ volume
• Active 60 °C heated chamber with automatic vent control
• All-aluminum dual-loop AC heatbed for even heat on large parts
• 10–15% class upgrade over CORE One L: nozzle wiper, GT1.5 belts, latest firmware
• Optional Advanced Filtration System (HEPA + carbon air filter) for ABS, ASA, PA, and more
• Open 1.75 mm filament, offline-first, user-serviceable, EU built
• Future INDX multi-material upgrade path
