The Sweet Spot of Volume 300×300×330 mm build area
The Best Setup Is No Setup
Top Quality Across All Filaments
PETG, ASA, Nylon… CORE One L’s precision remains consistent.
Convection heatbed Uneven heating? Solved!
CORE One L solves the biggest pain point of large‑format printing – unstable heating. No cold corners or warping.
A+ Heat distribution
Dual fans beneath the bed blast air across the massive hot surface, while special deflectors spread it evenly throughout the chamber. This ensures perfect distribution of heat.
Edge-to-Edge Uniformity
Most printers heat unevenly – this one doesn’t. The dual‑loop heating element delivers uniform heat across the entire surface. Fill it to the edges; nothing warps or peels off.
New Convection AC Heatbed
The CORE One L features a convection heatbed made from a cast aluminum block for perfect heat transfer. It reaches 60 °C in no time.
Back‑to‑Back with the Prusa CORE One
CORE One L doubles the print volume of CORE One with only a 10% larger footprint and adds many refined features.
