Known Issues

Absorbs moisture in hours

Cause: Polyvinyl alcohol is extremely hygroscopic

Fix: Print directly from a heated dry box and seal between sessions

Clogs at high temp

Cause: PVA degrades and chars above 215°C

Fix: Keep hotend below 200°C and never leave it idle hot

Slow water dissolution on big parts

Cause: Cold tap water is slow

Fix: Use warm water 35-40°C and gentle agitation; avoid boiling
