DIY filament dryer
Hi,
I'm looking for the best way to dry filament that tend to hold moisture over the time. I already tried using an oven at 75°C for 2 hours, but the result was deceiving: The filament was properly dyed, but a nasty odor of plastic remained for some days and the plastic of the filament pool was deformed :/
I'm looking for other ways.
I found an interesting project to make a filament dryer, based on a food dyer ( http://www.instructables.com/id/DIY-3D-Printing-Filament-Dryer/?amp_page=true ). Do you know other way to efficiently dye filament with no or limited drawback ?
I'm like Jon Snow, I know nothing.

Hi Christophe
So far, I have not had any printing issues when using filament which has not been stored properly, and I have some which has been left around for over a year.
However, I did have a problem with the printer (filament drive gear):
It seems that steam has been driven back up the PTFE tube and corroded the gear. The hole in the gear occurred exactly at the flat of the motor spindle. I have since purchased some stainless steel gears, but they are slightly larger diameter than the brass one supplied by Prusa Research, so until I can reprint the extruder housing with a the motor moved over a little, I am using the brass replacement from PR.
PLA has a glass transition temperature (the point where it moves from a solid state) is only 60 to 65 degrees, so any drying must be carried out at less than 60 degrees in order to retain the filament shape.
