Technical Data SheetPBT-GF Filament
PBT-GF is an FFF 3D printing ﬁlament, which is produced using BASF Ultradur® B 4300 G2.
PBT-GF is a polyester modiﬁed material containing 5-10% glass ﬁber, characterized bytemperature resistance, low shrinkage and easy-to-print property, with the ability to beprintable on non-heated chamber FFF 3D printers. It has excellent rigidity and tensile
strength, along with good insulation properties, allowing continues use up to 150°C.

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.
In case the ﬁlament has become wet, it should be dried before being used. Using a hot
dry air oven at 80℃ for at least 12 hours is recommended in order to ensure the print
success rate and quality.
If PBT-GF is used as the support material for itself, please remove the support structure
as soon as the model cools down. Otherwise the support structure can be permanently
bonded to the model due to excessive moisture absorption, which will make the support
hard to remove.
After the printing process, it is recommended to dry the model in the oven at 80-100°C
for 1-3 hours to increase the strength of the model.
