Posted · T-glase tore glass out of my UM2 bed

so I was printing a cookie cutter for my mom with some red T-glase and when I removed it from the print bed it left some wierd marking which after touching them I realized were chunks of missing glass which are now imbedded in the cookie cutter i printed

the build plate was at 60 degrees

hotend at 240

no special adhesive surface, just straight glass.

when removing the print, i just squeezed the print a little bit and it snapped off. no rough housing or use of any tools.

I've printed 3 spools of t-glase so far and this has never happened, I'm at a loss for words.

    Yeah this has happened to a few people using XT. I havent experienced it myself but it was happening quite a lot a while back.

    Good thing the glass has 2 sides :)

    Yeah I always try to leave my prints till they are ambient. I ended up with a spare glass anyway so I can just swap them if I want to do another print straight away.

    I believe this is what causes glas chipping.

    So it says to remove the print at 35c.

    Interesting as this seems difficult to me. At least with XT I often had to put my glass in the fridge to get the print off.

    the recommended bed temp is quite low at 45deg so I guess this would make it easier to get off
