yup with PEI bed you can go up to 120°C on the X1

<p>Most PEI sheets are rated for use at temperatures up to around 170–180 °C on a continuous basis. The actual maximum safe temperature that a PEI sheet may be subjected to might vary with the exact formulation and thickness of the PEI sheet. For temperatures above this range, PEI beds may deform or discolor due to material degradation. It is also important to consider the maximum temperature ratings of any adhesives or mounting materials used to fix the PEI sheet to the print bed, as sometimes these have lower temperature tolerances.</p>

# Do PEI beds have a maximum safe usage temperature?

(Asked by: username_0 on 2023-07-26)

I have a generic smooth PEI bed and a Bambu PEI textured bed. I've never used this bed material before and so have no experience with it.

Does PEI have a maximum safe usage temperature or at least one that I could reasonably reach during 3D printing on an X1 Carbon?

I don't want to accidentally toast it printing with a high-temperature setting, as there don't seem to be any trips or safeguards against it in the software.

The X1 Carbon is given for a max hot bed temp of 120 °C as per the manufacturer specs.

In fact, the PEI material itself can sustain temp up to 170 °C continuously. (Source: [Duratron® U1000 PEI data sheet](https://www.theplasticshop.co.uk/plastic_technical_data_sheets/polyetherimide_pei_1000_technical_data_sheet.pdf))
