Drying out filament

Temperatures and times needed to dry various filaments

As a rule of thumb, filaments shall be dried below the glass transition temperature (Tg) of a material-type to prevent crystallization / softening of the material that could cause the filament to stick together.

TYPE  	  	Temperature
---------------------------
PLA 	  	40 to 45°C
Tough PLA 	40°C
Nylon 	  	40 to 70°C
TPU95A 	  	40°C
Breakaway 	40°C
PVA 	  	50°C
PETG 	  	65°C
CPE 	  	65°C
CPE+ 	  	70°C
PC 	  	70°C
ABS 	  	60 to 70°C
PP 	  	Not needed
===========================
Dessicants
---------------------------
Silica Gel      65C (149F) at least 3 hours

Note that though calcium chloride can be dried out it requires a more complex method that just sticking it in an dehydrator oven and because of that it is not recomended to do at home.
