Broke my glass plate for the first time, what kind of glass


#1

looking to replace my glass sheet that broke. Note to anyone tinkering, dont rearrange all your cabling and forget to check your end stops. :frowning:

Anyway, does anyone know what kind of glass ships with the WIlson II kit? Is it straight up window glass or is it borosilicate?


#2

It’s borosilicate. I got mine from EBay (listing here).

Thanks Walter. I went down to the local hardware store and had them cut me two sheets of regular double strength 1/8" glass. have done a few prints on it since and doesnt seem to have much problem with heating and cooling. time will tell if it gets fragile. ordered a borosilicate one as well, so i’ll just use these until that comes.

Thanks folks.

I had a local glass shop cut a piece of 6mm plate glass for me. It cost me $15 Canadian, which is about $10 USD. I have been printing on it pretty regularly for over a year now. I use an electric paint stripper heat gun to heat it up to 70 or 80 ,it takes 3 or 4 minutes for the heat bed to become ready and heating switch to the hot end. I print mainly PETg on hairspray.

Shipping from the US to Canada is ridiculously expense, especially when eBay sellers use the eBay’s Global Shipping system which is a particularly big ripoff.
So buying a chunk of Pyrex is too expensive.

I think Pyrex is overkill, regular plate glass is plenty good enough given the temperatures involve.
FWIW that’s my two cents.
