Heat bed insulation

[Pappy3831]

Has anybody used heat bed insulation such like TH3D sells?  Thinking about it and seeing if anybody has first hand experience in using it and the pros and cons.

I bought some insulation for this purpose. I saw a video that suggested it with Voron 2's because the plastic sheet on the bottom warps at higher temperatures. However, I have not installed it yet and have not seen any other detail on this subject. I'm curious if anyone has experience with this as well.

I have installed the neoprene foam with aluminium foil insulation layer on my Voron 2.4 because of the bottom plastic sheet warping. Once installed the area below the heatbed is MUCH cooler and there are now heat issues below the heatbed at all. I also found that it heats up faster, retains heat better. I would do the same again in future.

Thanks for the info. Think I’ll get some.

I'v put a stainless steel sheet under my bed as a heat shield:

I used a cheap baking pan with the right dimensions and did a bit of metal work on it to fit it. It looks good and is surprisingly heavy and stiff.

I've seen some discussions suggesting the use of a panel made from Aluminum Composite Material (ACM).

Any one have any thoughts about using such?

I use ACM and automotive firewall wrap keeps my enclosure at the perfect temp for nylon
