I'm having a really hard time printing on my aluminum heated bed... Cleaning it just results in it being scratched (trying to scrape dried hairspray/glue/etc off) and I don't think it is particularly flat either.

I was thinking of stopping by the dollar store on my way home and getting several picture frames and using the glass from them as interchangeable glass beds - this would also make it easier to take them off the printer to clean without needing to re-level the bed every time as the aluminum base would stay-put.

Do you guys think the quality of it would be okay to print on? (withstand the heat, be flat enough, etc) I'm planning to coat it in purple-glue-stick as I have heard that works well for adhesion purposes.

For reference: Printing PLA, Prusia i3 printer.

I use normal glass plates on top of my heated borosilicate glass bed all the time.


  • very cheap (about €3 where the borosilicate glass bed of my printer costs about €80 to replace)
  • no need to wait till the bed cools down to start a new print. Just put on an other sheet of glass and start over. (I use 3dlac to make my prints stick better so trying to remove a print from a hot borosilicate glass bed often results in a chipped glass)
