The Dual Zone heated build plate set consists of 3 parts:
1. KEENOVO silicon heating pad with dual heat zones: inner zone 200*200mm, outer zone 400*400mm.
you can turn off the outer zone when printing small objects or turn it on for large objects,
so as to save power for you effectively.
moreover, it's integrated with a precise digital controller, plug into the wall directly.
it can control the speed of heating and provide Display in Fahrenheit(Celsius by default) as well as timer function.
2. Borosilicate Glass: it won't deform even heating to 500℃, so as to ensure a very flat printing surface.
3. Custom Print Surface: it can improve bed adhesion obviously, even don't need to heat bed at all when printing PLA.
