I agree with user "heartless"'s opinion: The filaments will inevitably absorb moisture, and their placement doesn’t really make a difference. It's best to use them with a filament dryer, or if you're as lazy as I am, just bake them in the oven before use.

simply put, if it is out in the open, it is absorbing moisture. period. there is no getting around that.

places with high humidity (Florida) are going to be worse than places with low humidity (southern Arizona), but the filament will absorb moisture regardless - just a matter of how much and how quickly.

Most likely not, as the humidity has soaked in to the filament. The only way is to assume there is humidity in it and dry it. I make it a practice to dry every spool a minimum of 12 hours before use. Even new spools that where sealed as I have had new sealed spools have moisture in them as well. I don't want to run out mid print and put on a new spool only to find out it has moisture in it and now my print looks like a sponge.

I would like your honest opinion. If i take a piece of Bowden tube about 3 feet long and seal a humidity probe in one end would it read the amount of moisture in the filament when inserted into the tube?

Thanks
