Some filaments stick hard to some build plates. For some objects that is a desired result and the object is easily released from the bed when the plate cools down and/or when the plate is flexed. I find that the base of the prime tower is difficult or even impossible to remove from the build plate. The not very dense prime tower first layer flexes with the plate cool down and flexing and does not release.
I would like a setting that would put the first few layers of the prime tower down as solid (100% infill) layers. The number of solid layers should be user select-able. This would allow the layers to release when the bed cools and/or is flexed. The feature could also be useful for brims.
Just tell us which filament you’re using, and you’ll get plenty of tips that make this a breeze. Depending on the filament, the solution can range from putting the print plate in the freezer for five minutes after printing - to using isopropyl alcohol with certain materials.
For almost every filament, there’s a way to make things easier. If it’s PLA, for example, try putting the print plate in the freezer for a few minutes after printing.
I know about those solutions that can be used after the problem exists. And some preventative measures like glue on the bed. But some plates could be damaged by freezing or alcohol. My freezer may be full. Glue has it’s own problems. Etc.
I think my suggestion would prevent the problem at the cost of a few pennies of filament (maybe not even a penny). And, though I am not familiar with the coding architecture of slicers, it seems like it would be pretty easy to implement such a feature.
This might be slightly off-topic, but that’s actually the first time I’ve heard that. You’re not supposed to leave it in there for ages, just about five minutes to cool down.
As I said, you don’t seem willing to tell us which filament or even which build plate you’re using. That’s perfectly fine, and I respect that if you’d rather not share those details.
Bambu is probably not going to implement that. You’ll likely have a much better chance of improving your workflow than waiting for changes to the software.
The main issue is that this would likely introduce new problems, because the prime tower serves a specific purpose right from the very first layer. There are quite complex calculations going on in the background, so it’s not as simple as it might seem at first glance.
Why Freezing Isn’t Recommended: Manufacturers do not rate the frosted polymer coating for sub-zero temperatures. Extreme thermal shock or moisture condensation from a freezer can degrade the delicate surface texture or cause the coating to delaminate from the steel sheet.
The JUUPINE GECO Plate is great for PLA for most models, but the prime tower sticks hard. Again freezing is a workaround for a problem I think could be prevented.
I totally don’t know how complicated it is. I was just guessing. But I think it is a good idea, and I would love to see it get on the developer’s feature request list. Then experts can make a cost benefit analysis.
I specifically said “cooling down,” not “freezing”. By the way, I checked the manual, and that text you posted doesn’t appear there at all? On the contrary, it says exactly what I’ve been writing all along:
Prints difficult to remove: Ensure the plate has cooled completely. Gently flex the plate as described above.
Print Removal: If prints are particularly stubborn, ensure the plate is completely cool before attempting removal. The flexibility of the plate is key; gently bend it to pop off prints.
