Why Choose S3DPS PBT Filament?
PBT, a member of the polyester family, features a semi-crystalline structure similar to PET but with enhanced mechanical durability and thermal stability. When combined with glass fibre reinforcement, it provides:
Higher tensile strength
Increased flexural strength
Greater impact resistance
Enhanced print stability
This makes S3DPS PBT PRO an excellent choice for engineers, manufacturers, and makers needing strong, reliable, and temperature-resistant prints without the extreme difficulty of printing nylon-based composites.
