Watch It in ActionCORE One L Reviews

Uneven heating? Solved!

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.

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.

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.

Edge-to-Edge Uniformity demonstration

Made to Run Forever.

Unrivaled exoskeleton steel frame for maximum rigidity.
Heavy‑duty components built to handle continuous 24/7 operation.
Long‑term support – spare parts guaranteed 5 years after release.

Prusa is the secure option

95% of desktop 3D printers sold are made by Chinese companies. Prusa is the remaining 5%. Does origin matter? Yes.

All Chinese companies are required to cooperate with state intelligence (National Intelligence Law, 2017), hand over encryption keys (Cryptography Law, 2020), and provide data to authorities regardless of where it's stored - even on EU or US servers (Data Security Law, 2021). Product designs and 3D models a legitimate target too (2023 Counter-Espionage Law update).

“There is a real risk that data on prints, design models, or production processes could be transmitted to servers beyond the user’s control, including to the territory of the PRC.”

2025 — NÚKIB
NUKIB Quote

“Really, if anyone in the product design world were to come to me and ask which 3D printer they should buy for prototyping, the Prusa CORE One L would instantly be my recommendation.”
