I’ve had a weird experience with ABS on a glass print bed, it basically melted the glass. I posted details on the 3dhubs talk forum with the same title. There is a picture now too. Any clue what is going on?

No, your glass bed did …not…melt !

there was no puddle of glass !

You print was stuck to the glass bed, and when you removed it you took a part of the top layer of your glass bed,

time to turn it over, and next time buy a new glass bed :slight_smile:

happy printing.

If it actually melted, you might not be using a glass bed, it could be an acrylic bed, which is dissolved by acetone in the same way as abs.

I appreciate the response. I am not imagining what I experienced, and it was most certainly a malleable blob of glass that returned to a rigid state after some time. I touched it and it deformed around my finger. I do not believe it was melted as in got up to a temperature that would melt glass, but there was some sort of reaction with the ABS or something on my print bed.

I guess this is the most plausible explanation, but I bought the glass bed from FlashForge, which claims of the glass: “The Pro-Formulated Thermal Glass is a heavy-duty glass plate…”, so I’m pretty sure it is glass. When it hardened, the shards that came off the raft broke like glass when I pushed on them with the tip of my pen.
