Technical Data Sheet
Flexible Filament
Flexible is an FFF 3D printing ﬁlament, which is produced using PBAT, a biodegradable
material known for its safety and environmental friendliness. Flexible ﬁlament has
excellent ﬂexibility and good ﬂuidity. It oﬀers good dimensional stability, no warping, nocracking and strong layer adhesion, with the ability to be printable on various FFF 3D
printers.

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.
PBAT is a polymer 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 Flexible ﬁlament
after its package being opened should be used up as soon as possible.
If issues like bubbles or severe stringing occur during printing Flexible ﬁlament, please
dry the ﬁlament in a hot dry air oven at 60℃ for at least 5 hours before use.
