PVA support material crackles as it extrudes

Recommended Posts

It is not ruined. It is just going to crackle and pop a bit and tend to produce more carbon on the nozzle. It is what it is. But I would not junk the spool. But, if you are using a space heater, it can still absorb moisture from the open air. At least with space heaters I am used to using.

 

An oven with tight controls or a food dehydrator works best.

 

But as long as it continues to print and provide support, use it. That stuff is expensive.

When your PVA has too much moisture, we recommend heating the filament for 2 hours at 45-55 °C. The easiest way to do this is by putting the spools on the heated build plate (for example in a carton box) at the required temperature (45-55 °C). Warning: do not use a household oven. Make sure that the PVA filament has cooled to room temperature before inserting it into the 3D printer.
