Technical Data Sheet
PVA Filament
PVA is an FFF 3D printing ﬁlament, which is produced using a thermoplastic polyvinyl
alcohol modiﬁed material. PVA oﬀers excellent dimensional stability, no warping orcracking and is easy to print. It is commonly used as a support material in 3D printing due
to its water-soluble nature.

Cautions:In order to prevent moisture absorption and contamination, supplied packaging should
be kept closed and undamaged. For the same reason, partially used ﬁlaments should bere-sealed before storage.
PVA is a water-soluble material. Exposure to moisture, oxygen in the air, and UV light will
accelerate its aging. In order not to aﬀect the ﬁnal printing quality, the PVA ﬁlament after
its package being opened should be used up as soon as possible.
