1 pcs of 235x235mm Borosilicate glass perfect for a completely level build platform.
Long time heat resistance of 450° C
ThermaI shock of 270° C
The thickness is 3mm and the corners and all edges are sanded.
For getting PLA and ABS to stick to the glass, we recommend using some adhesive.
To print with ABS we suggest a heat bed underneath.
PETG sticks very well to clean glass, and when finished printing and the glass is cooled down, the printed part will come off quite easily.
Please note a piece of glass is never completely flat and it can bend as much as -+0.1mm/100mm.
