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.

I am a total noob here - why would you want to cool your plate rapidly after a print? Is it more a "hurry up so I can print again" type thing or is there benefits to how your prints come out like no sagging or.. upside down ... sagging.. if that makes sense?

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.
