Prusa CORE One L+ — Double the Volume, Refined for Everyday Use

The Prusa CORE One L+ is the large-format sibling of the CORE One+, now updated with the same round of usability improvements introduced across Prusa’s 2026 lineup refresh. It keeps the CORE One L’s headline feature — double the build volume of the standard CORE One in only a 10% larger footprint — while adding cleaner print starts, better-looking surfaces, and easier day-to-day maintenance.

Assembled and pre-calibrated from the factory, it’s ready to print out of the box.

300 × 300 × 330mm — Large-Format Without the Bulk

The CORE One L+’s build volume is approximately 30 litres — double the standard CORE One — opening up large single-piece prints, tall models, and high-volume batch runs that don’t fit on smaller machines. The rigid steel-aluminium exoskeleton frame maintains dimensional precision across the full build area, with minimal vibration even at speed.

What’s New in the L+ Refresh

New GT1.5 Belts

Finer-pitch belts than the previous CORE One L, reducing fine repeating surface patterns on large, smooth flat walls — a particularly noticeable improvement given the L+’s larger print surfaces.

Integrated Nozzle Wiper

One of the most requested community features, now standard across the refreshed lineup. The wiper automatically cleans the nozzle before every print begins, so loose strands and small blobs don’t get carried onto the build sheet. It’s a standard, easily replaceable part.

Redesigned Bayonet Filament Path

A reworked filament feed path reduces friction and dramatically cuts the buckling and jamming issues that have historically made flexible filaments like TPU frustrating to print. The bayonet spool system also enables one-handed spool changes — a small detail with real day-to-day impact, especially on long print jobs or when swapping materials frequently.

AC Convection Heatbed

The CORE One L+ uses a cast aluminium AC convection heatbed with dual-loop heating, delivering less than 2°C temperature variance across 99% of the print surface. Two fans mounted under the bed create a convection effect that heats the chamber significantly faster than passive heating alone. The result is even first-layer adhesion, warp-free printing on engineering materials, and faster heat-up to working temperature.

Active Chamber Heating — Up to 60°C

The enclosed chamber with active heating reaches up to 60°C for warp-free printing with ABS, ASA, PC, PA, and other engineering materials. The active system manages temperature in both directions, keeping the chamber cool enough for PLA and PETG with the door closed while providing warmth for demanding filaments.

Nextruder with 360° Cooling

The proven Nextruder toolhead delivers flawless overhangs up to 75° without support structures, dramatically reducing material waste and post-processing time. The high-flow nozzle handles fast printing across virtually all filament types.

Automatic Venting

An automatic top vent removes one of the most common user error points on enclosed printers — no manual adjustment needed between low-temperature and high-temperature material jobs.

Upgrade Path & Ecosystem

MMU3 Multi-Material

Fully ready for the MMU3 add-on, printing with up to 5 filaments simultaneously.

HT Hotend Upgrade

The optional HT Hotend enables nozzle temperatures up to 400°C for high-performance polymers like PEKK-CF and PPS-CF.

Open Ecosystem

PrusaSlicer with factory-tuned profiles for 200+ filaments, Prusa Connect for remote management, and full modder support — every part is screwed, not glued. No walled garden, no locked firmware, no forced filament vendor.

Supported Materials

PLA, PETG, Flex/TPU, PVA, PC, PP, CPE, PVB — standard setup
ABS, ASA, HIPS, PA — with Advanced Filtration System
High-performance polymers — with HT Hotend Upgrade (up to 400°C)
