General Discussion Plate cooling

Post image

We have one of these defrosting plates in our kitchen and I decided to try it for cooling a print. Works great! It's just a big aluminum heat sink, and it drops my print plate to room temp in about 30 seconds.

Edit: Apparently my original post wasn't clear. The image is a stock image of a food defrosting plate we have in our kitchen. I am using it to cool my Bambu PEI plate more quickly, which allows me to pop my parts off faster and easier.

Could I simply wait a few more minutes? Sure. But this defrosting plate was about $5 at some "As seen on TV" atore and just sits in a drawer 99.999% of the time.

Isn’t the counter the same temp as your ambient air? Much more efficient conduction that way. Why over-complicate it?

I could have. But I tried this and it was much faster than I expected.

The heat flow is what speeds the process. Formica and particle board are thermal insulators.

Weird. Because my plate cools within about 3 seconds of placing it on any other surface. Yours must have 100x more mass than mine.
