Product Review

If you want to make your printing platform flat enough, ideal stuff is glass sheet. Borosilicate glass is rated for higher temperatures than normal sheet glass making it a better material for use as a heated bed. After cracking a few sheets of normal glass from rapidly cooling or heating, borosilicate glass will quell your frustrations.

Note
Please note that this glass is about 1/4" short on all sides when use on CR-10, 10S 300 series due to CR-10 heat bed size extension.

Features:
* Borosilicate is a very high temperature glass. It has a melt temperature of about 800° C and a very low thermal expansion coefficient.
* Resistant to thermal shock compared to regular glass.
* Prepare a second plate and quickly switchplates when a model finishes printing. This significantly reduces printer idle time between prints.
* Reduces warping, however platform has to be properly leveled as is the case with any platform on a 3D printer.
