The ideal surface for 3D printing, borosilicate glass can be rapidly heated and cooled. Borosilicate glass is resistant to thermal shock as well as thermal expansion. (200 mm x 214 mm)
A piece Borosilicate glass meant for use on the bed of a 3D printer. Its thermal properties make it useful for printing ABS and PLA, especially in conjunction with a heated bed. With ABS we recommended adding some Kapton tape and when printing in PLA we recommended adding blue painter's tape to the surface.
