Heated Bed Insulation
Revision as of 04:26, 4 November 2015 by Mc2lagrange (Silicone cooking mats conduct heat, but I'm not going to remove it since this is my first edit. Melamine is awesome and hard to beat, can easily get me to 110C now when I couldn't make 100C with silicone sheet (conductor not insulator!))
It's a good idea to insulate the underside of the heatbed in order to get a faster heat up time and a overall better thermal performance. For higher temperatures, an insulation might even be required.
Solutions found to work are:
- Cork plate (more dense wood (eg plywood) is better than nothing, but tends to conduct heat away too quickly).
- Cotton batting.
- Rescue sheet, see e.g. Robert's Heated Bed ie the silver or gold rescue blanket used by hikers.
- Glass fibre soldering/plumbers/welding mat (approx £3 on ebay)
- Silicon cooking mat
- Teflon cooking sheet (doesn't insulate very well, but doesn't melt/burn, and can keep glass fibre contained)
- Melamine Foam (Excellent insulator but thinnest is typically 1/2", easily laminated to heated bed with 468MP tape. Doesn't burn and high temperature tolerance.)
