What happened
Prusa announced the CORE One L on October 31, 2025, as a larger enclosed CoreXY sibling to the CORE One. The launch focused on printing bigger parts with fewer joins.
The announcement described an actively heated chamber, a revised heatbed and optional connectivity. A Critical Infrastructure Edition was also offered with a mainboard designed without Wi-Fi circuitry.
This is a retrospective on the original L announcement. Later L+ upgrades and shipping updates are separate stories, so launch-era specifications and plans should not be confused with every current configuration.
