Question: Humidity controlled cabinet (lemmy.world)

Hi all,

I'm doing an experiment with a cabinet for filament with a small dehumidifier in it. I can get it to sit at 35%, but not much lower. I've sealed the cabinet with foam tape, and dried most of the filament first.

Are there any tricks to help improve performance of the mini dehumidifier? Maybe adding more heat to the cabinet?

The goal would be to use Home Assistant and the humidity sensor to turn things on and off as needed.

Thanks!

I remember an article a few years ago about an experimental tube system that just rapidly dehydrated segments of filament in line on the way to the printer. Was hoping to see a commercial version of something like that by now as it just sounds so efficient. This setup looks extraordinarily unefficient on the other hand. I understand your efforts for better work flow, but to heat and dehumidify this properly will be a significant energy sink.

    Assuming I can get it working, not really. Your described method would be good for occasional prints, but terrible for higher volumes. Keeping an area at a target humidity (especially a small one) is much more efficient than a constantly running device.
