What changed from the CORE One L to the L+?
The main change is a silicone brush that wipes the nozzle. Earlier Prusa machines cleaned the nozzle by tapping it on the bed before bed leveling, which left small dots of filament on the plate. With high-temperature filaments that ooze, the wiping step failed more often, and the printer then switched off bed heating while waiting for the user. The reviewer says the brush makes the machine dependable for unattended printing.
The L+ also gets GT1.5 timing belts and drive gears with tighter tooth spacing, which the review links to smoother surfaces. The machine is calibrated at the factory, so the first print can start about five minutes after unboxing. It is sold only as a fully built unit, with no kit option.
How does it perform in long-term use?
The reviewer ran the earlier CORE One L for more than 1000 hours, printing abrasive carbon and glass fiber filaments without problems. The build volume is 300 x 300 x 330 mm, and the frame is metal with a heated chamber. The bed is a thick aluminum plate that switches automatically between 110 V and 220 V. The hardened steel nozzle is included next to the installed brass CHT nozzle. The machine can also be used entirely offline, which the review notes is useful for businesses and public bodies with strict data rules.
What are the limits and options?
The hotend still tops out at 290 °C, below the 300 °C common in this class, and below the Bambu H2S at 350 °C and the Qidi XPlus 5 at 370 °C. Prusa lists an optional HT hotend reaching 400 °C for $199, but it was out of stock at the time of the review. An optional filtration add-on with HEPA and activated carbon filters is available and can be connected to an HVAC system. The L+ is also compatible with the Prusa INDX conversion kit, priced at $799 for four tools or $1,079 for eight.
