Talk:Heated Bed Insulation

I too think it's a good idea to use some kind of thermal insulation under the heatbed. I noticed that the MK2B heatbed I am using can easily reach 60C or 65C when printing PLA, but it's an entirely different story trying to reach 100C when printing ABS (I am using a 12V power supply and RAMPS electronics).

I am going to try the cork sheet method and will report here on how much of a difference that makes.

Silicone Cooking Mat is a heat conductor, not insulator

Silicone rubber is a good heat conductor, it shouldn't be listed as an insulator!

I used this because RigidBot folk recommended it, but silicone rubber and Silpat in particular are good heat conductors. Of course you want that for cookies, you don't want the bottom colder! :)

Melamine is far, far better though I can't find it less than 1/2" which is a bit thick and almost doesn't fit my printer.
