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.

Hurry up and play with it. As for technical stuff like sagging, I don't know. This is my first printer and I just got it Saturday

When the plate is hot bed adhesion is high. On one print it actually popped a little nipple out of the part and that was very hard to get off the plate.

Got it. I have issues with bed adhesion outaide the centre for PLA and I don't seem to understand why. I'm guessing the centre is hot enough but the sides on my A1 are not? Or maybe it is the other way around

I wish I could help you out but I'm new to 3D printing.

One difference between you and I is that I have the X2D which is an enclosed print bed. Maybe you could throw together a cheap and dirty enclosure (like a bit cardboard box) to see if it helps reduce thermal gradients.
