Dealing with humidity

[jonohoff1988]

I have a Bambu A1 printer. I invented something that i make out of 85A TPU, which everyone knows sucks up water really bad. I got a dehumidifier for the room, but I think it has a sensor that throttles the amount of humidity it captures to keep the room at a level that is considered "comfortable for humans". I have a tiny bedroom designated to printing, and this thing sucks up like an ounce or 2 of water a day. I believe it could suck up 12 oz a day if it wasn't trying to accommodate human comfort. Does anyone know anything about these things? I was considering finding the sensor that it uses, and tricking it with a small vessel of water in front of it so it thinks the air in the room is wetter than it is. The parts I want to make, if I can figure out the humidity, will run for 20 hours straight then I would swap in a spool from my drier box and put the first spool in that box. and just alternate. But with as wet as the air is, I can only print 3 of these (6 hours) before I start getting pretty bad stringing Eventually I will move to having these injection molded these when there is enough demand for them, but don't really wanna spend 40,000 dollars on that until I know this product is going to be popular. I live in Kansas City, and it's just humid as hell here even with the AC running. I considered building some sort of "tent" that the printer and dehumidifier are in to minimize the space it needs to dry, but I think it would still try and maintain the people comfort level.

I would love some feedback on how to deal with this.

I posted this a few weeks ago and didn't get any relevant feed back, so I'm trying again. your box feeding PLA while printing does not mean the TPU will. i need someone who has made this work with TPU 85A or softer to chime in

Dry your filament in a food dehydrator that gets hot enough to dry it out... Build an enclosure for the printer, and keep the room at 70-72 degrees with a window ac. I live in Philadelphia, no place more humid that Philly other than FL!

Keep youf rolls that are open in a vacuum bag (kind you put blankets in) when not in use. I print with ABS/PETG/TPU and Nylon .. Nylon needs to be run for 12-24 hours in the dehydrator before every use.
This is what I use, you have to cut some of the screen sections but you can put 2 rolls in at once. https://www.gopresto.com/product/pre...hydrator-06301
