If you are concerned, keep the raw material dry and sealed, then add it a few hundred grams at a time (a few hours worth) to the hopper - that way it has less time to be exposed to moisture for extrusion.

I plan on getting a food dehydrator to pre-dry pellets before trying to extrude anything. However, my local humidity is 65% !
If it takes several hours to extrude a batch of pellets, then doesn't that put them at risk of absorbing water from the air while extruding? Do I need to take extra steps to make the pellets safe from the humidity?

I know for PLA/ABS this probably isn't a major issue, but I am planning on trying to extrude Polycarbonate and Nylon, which are both more hydrophilic.
