T-glase tore glass out of my UM2 bed

Recommended Posts

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 :)

why would something like this happen? is the filament sticking too strongly to the glass? it seems odd that I've printed multiple spools of this and it has never happened before

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
