SUNLU TPU 1.75 mm, 1 kg 3D Printer Filament, Gray

The SUNLU TPU 95A Flexible Filament Grey 1.75 mm 1000 g is a grey thermoplastic polyurethane material designed for Fused Filament Fabrication (FFF) and Fused Deposition Modeling (FDM) 3D printers. It combines rubber-like flexibility with structural strength, making it suitable for functional parts that need to bend, compress, or absorb impact. Typical applications include gaskets, seals, and protective covers. The spool contains 1 kg of filament and is intended for users who need elastic printed parts.

The manufacturer specifies a nozzle temperature of 210 °C and a build plate temperature of 50 to 60 °C. The material supports print speeds of up to 80 mm/s. Its specific gravity of 1.21 g/cm³ is consistent with standard TPU density. Printers must have an extrusion system capable of feeding flexible material reliably to prevent clogging or filament buckling. Direct-drive extruders feed flexible filaments most consistently. Users should check their hardware compatibility before printing.

• Shore 95A hardness: Indicates the material's flexibility and resilience for functional applications.
• ±0.02 mm diameter tolerance: Maintains dimensional accuracy for consistent extrusion.
• 900% elongation at break: Allows printed parts to stretch extensively without fracturing.
• 47 kJ/m² impact strength: Absorbs sudden mechanical shocks for durable use.
• 31 MPa tensile strength: Resists pulling forces before permanent deformation or breaking.
• Not AMS compatible: Requires a direct-drive or short Bowden extruder setup for reliable feeding.
