SITALL GLASS HEATBEDS
Sitall is a Russian glass works, specializing in premium packaging products. Based in Roslav, 400km (250 miles) southwest of Moscow.
Sitall Glass is something they developed for the 3D Printer market and for RepRap print Heat platforms.
Without any other adhesives Sitall glass work likSte Wolfbite its molecules start moving and of course expanding slightly which when heated up keeps the prints glued.
All normal Filament types works on this glass bed. Its hard to rip even with significant force when still above 85C. But when printing ends and HeatBed cools to 70-80C, ABS model will unstick by itself.
Here is a demonstration of printing on Sitall glass
Sitall glass is also an extremely tough, chemical and heat resistant build surface which lets you print directly onto the glass surface, without Tape, glue stick, hairspray or any other adhesives. Unfortunately the Bulldog clips are not included with the orders but can easily be bought separate
A little strength demonstration on Youtube
Excellent build surface for both ABS, PLA, FLEX

Resistant to thermal shock / temperature cycling far in excess of intended use
Cut for almost all heated bed platforms
