Filament drying experiment. Place a spool of filament in a theoretical air sealed box along with a thermometer & hygrometer at room temperature. Now, heat the air/filament to 150 deg F. Read the hygrometer. Now, let the filament cool down to room temperature without opening the box. See the hygrometer reading return to similar room temp humidity? The RH went down when heated and returned when cooled. Any loss of water in the air is due to it now being more in the filament. Run the save experiment with dry packs instead of filament, and the air RH should be lower because the packs are designed to hold more water than air. Same goes for types of filament holding more water than other's.
The best drying filament inside whichever designed container requires air to absorb water inside the filament. This is done by heating the air & filament to make the air more attracting. This condition mostly occurs on the outermost filament winding and especially the unwrapped portion. The optimum designed dryer would have heated air circling the filament with cool plate. The cool plate would condense the vapor to water and drain it. This device would be cost prohibited and, in some filament types, unnecessary, even harmful (too brittle). The best filament storge is sealing it in a container while still warm. Include dry packs and vacuumed with a humidity measuring device or strip.
Huh? Sorry, but I have to say to anyone watching this channel's suggestions about drying filament ... follow the mfg instructions. Don't follow this channels advice. I'll explain the effects of "dryer" volume by asking to run an experiment. You'll need a plastic bag, 2 paper towels and a room. Wet the 2 paper towels under a faucet until soaked. Squeeze out excess water and place 1 towel into the plastic bag. Close the bag. Leave the 2nd paper towel next to it on a dinner plate. Check both paper towels for wetness in 3 hours. You are likely to find the towel inside the bag is wetter. Both were drying in equal air temps, showing that a larger volume enclosure could hold more water vapor. Room relativity changed little while the bag's relative humidity soared. Maybe to 99% RH.
Drying filament is about relative humidity within a given space. Relative humidity is about temperature. The higher the temperature, the more humidity air can hold and vice versa. Air conditioners control humidity by lowering air temperature which lowers the amount of actual humidity the air can hold. A/C's condense the air's above 100% humidity... as does a glass of cold beverage. Heated air can hold more humidity than room air, which is how we dry our clothes. Now, what would happen if you turned the clothes dryer on and left the door wide open (I mean, besides clothes falling out)? It takes longer to dry your clothes, right? Well, putting a gap in a filament dryer's lid has the same effect as well as making the heater work harder to heat the new air/humidity coming in while the heated air leaves.

Also with the P1S?

The P1S doesn’t seem to have this option.
you dont have the button and timer, just get in bambu sutdio, 50-70°C Bed temp and 50% chamfan. same Effekt.
Isnt 70°C a little high to dry PLA?
Probably if it was a regular size filament dryer but I’d imagine 70 for the whole Bambu lab chamber isn’t too bad

Cheaper, easier , better option than the X1C as a dryer: Buy an Anycubis Kobra 3 combo....its ACE does all 4 rolls at once and keeps them dry
I’ll have to check it out
