    I have had limited success heating the filament to dry it out. I have managed to dry the filament successfully. I purchased a couple of army surplus night vision goggle cases with a purge valve. The cases are sealed and made of aluminum and are strong enough to withstand a vacuum without imploding. The cases hold 7 rolls of filament each. I removed the purge valve and tapped with a 1/2 NPT tap. The aluminum is just thick enough for this to work. I put in a 1/2 npt male to 3/8 hose fitting. I had an old vane type vacuum pump lying around and attached to hose fitting via a gas valve.

    I took the case down to 25 inches of vacuum overnight with rolls of plastic that just would not print well. In the morning I took out a roll and printed. To my surprise the roll of plastic that was the worst had no problems. The amount of stringing was markedly reduced.
