Topic: PLA and moisture
I've read that the moisture can lead to bubbles in the the extruded filament and that it can affect the mechanical properties of the filament but I've not seen much about how it affects the extrusion process itself. There are plenty of warnings about the need to pre-dry PLA pellets prior to extrusion. So what exactly is the effect of moisture on PLA extrusion? Does it make it harder to extrude or make the filament diameter more difficult to control or what?
Has anyone had any success extruding PLA without pre-drying?
