## Watch It in Action CORE 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](https://assets.prusa3d.com/cdn-cgi/image/width=2898,height=1638,quality=85,format=auto/866c5f7d-0e35-4215-b70d-bda64e399ae5.jpg)

## 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.”
