Why Choose S3DPS PBT Filament?
PBT is part of the polyester family and offers semi-crystalline structure with properties similar to PET. When reinforced with glass fibre, it significantly improves tensile strength, flexural strength, and impact resistance, making it ideal for demanding, load-bearing components. This filament provides professional-grade results with reliable printability on most FDM printers.
