Printing on Glass with your Prusa i3 MK2 – Ohhh So Smooth
Scott Smith

Any of you that love printing on glass because of the beautiful “Smooth as glass” surface will love printing on glass with your MK2.

This short video will show you how easy it is by adding a few lines of code to your start up script within your slicer. I would recommend going to you’re hardware store with the measurements of your print bed and have a couple pieces cut by someone familiar with cutting glass and even have them smooth the edges to help prevent cracking and the possibility of cutting yourself.


You’ll also need a few chip clips or some method to hold the glass securely to the hotbed.

Follow along by watching the short video below. The Gcode for your start up script can be copied from the text display below the video.

Note: You must accurately measure the thickness of your glass and change the value in the gcode before running the script.

Update: I have also checked the bed temp with a laser thermometer and the temp of the glass is about 7 degrees cooler than the hotbed so adjust accordingly for your environment.
