<p>So I’m kind of a newbie to 3D printing. I got my Ender 3 about 3 days ago and some PETG filament to accompany it. These are the slicer settings:</p>
<ul>
<li>Hotend: 235 °C</li>
<li>Initial bed temperature: 80 °C</li>
<li>Bed temperature: 70 °C</li>
<li>Layer height: 0.12 mm</li>
</ul>
<p>I also use a brim on the outside of the prints. Every time I print, some of the bottom layers stick onto the bed. I’ve seen somewhere that if you heat it to 70 °C you can scrape it off, but that doesn’t work for me.</p>

This reason for this to happen has been answered in other questions, see e.g. [this question](https://3dprinting.stackexchange.com/q/14783). Your nozzle is probably too close to the bed. Furthermore, you could use a bed adhesive spray as a release agent, a common brand is 3DLAC, but there are many others.

In contrary to other plastics, PETG is generally sticking too well to the buildplate. I had good experiences by using a structured PEI spring steel build plate. It prevents making any mess with glue or other mentioned release agents.
