Prusa CORE One L+ 3D Printer

Double the build volume of the CORE One with a 60°C heated chamber, now upgraded with an integrated nozzle wiper and GT1.5 belts for cleaner starts and smoother surfaces.

What's New in the L+

The CORE One L+ takes the proven large-format CORE One L platform and folds in the latest hardware from Prusa's 2026 lineup refresh, at the same price as the outgoing model.

• Integrated nozzle wiper cleans the nozzle before every job for reliable, tidy first layers
• New GT1.5 drive belts with a finer tooth pitch reduce repeating surface patterns for visibly smoother walls
• Every firmware improvement from the CORE One family comes pre-installed, so day-to-day operation needs less babysitting

Think Big. Print Bigger

With 300 × 300 × 330 mm (30 litres) of enclosed build volume, the L+ prints big functional parts, jigs and fixtures, architectural models, cosplay props and helmets in one piece instead of gluing sections together. The all-aluminium heatbed with dual-loop heating holds the surface within 2°C across 99% of its area, so large flat parts stay stuck and come out without warping.

Materials

Optimised out of the box for PLA, PETG and flexibles, while the 60°C heated chamber unlocks reliable ASA, ABS, polycarbonate blends and nylon. The included abrasive-resistant nozzle handles carbon and glass fibre composites, and the optional Advanced Filtration System (HEPA + active carbon) is recommended for heavy ABS/ASA use. The optional HT Hotend upgrade takes the nozzle to 400°C for advanced engineering polymers.
