BALITENSEN 235x235x3mm Borosilicate Glass Plate for Creality Ender 3 Ender 5 CR20 Glass Bed
BALITENSEN 235x235x3mm borosilicate glass plate for Creality Ender 3, Ender 5 and CR20 glass bed upgrades.
Flatness and glass type lead the decision. Borosilicate glass resists thermal warping better than ordinary float glass and stays flat across many heat cycles. Thickness of 3mm to 4mm holds shape without flexing, and some beds add a special coating that grips filament without glue. Check the dimensions against your heated bed, whether corners are clipped for bed clips, and if edges are smoothed so you avoid cuts during handling. These guides suit printers who want a perfectly flat surface and a glossy part bottom, especially for large flat prints prone to warping on flexible sheets. Plain glass needs an adhesion aid like glue stick or hairspray for many materials, while coated glass grips on its own. A practical tip: let the bed cool fully before removing a part, since prints often release on their own with an audible click once the glass contracts, sparing you the scraper entirely.
