SUNLU TPU 95a 1.75mm 1kg Black Filament

The SUNLU TPU 95A 1.75mm Black Filament combines the flexibility of rubber with the durability of plastic, delivering exceptional performance for applications requiring elasticity and impact resistance. With a Shore hardness of 95A, this thermoplastic polyurethane strikes the perfect balance between flexibility and structural integrity, making it ideal for functional parts like phone cases, automotive components, shoe soles, gaskets, and protective gear. The advanced formulation provides excellent layer adhesion and smooth surface finish while maintaining superior wear resistance, chemical resistance, and anti-aging properties.

Engineered for reliable printing with both standard and high-speed capabilities, this TPU filament offers consistent extrusion and dimensional accuracy that produces professional-quality flexible parts. The classic black colorway provides a sleek, professional appearance perfect for industrial applications, consumer products, and prototyping where aesthetics matter as much as performance.

Key Features:

Optimal 95A Shore Hardness: Perfect balance of flexibility and firmness, providing rubber-like elasticity with enough structural integrity for functional parts and mechanical components that need to maintain their shape under stress.

Superior Material Properties: Excellent wear resistance, oil resistance, chemical resistance, and anti-aging characteristics ensure long-lasting performance in demanding applications and harsh environments.

Exceptional Layer Adhesion: Advanced TPU formulation delivers outstanding interlayer bonding and smooth surface finish, eliminating common flexible filament printing issues like delamination and poor surface quality.

High-Speed Printing Capability: Engineered for printing speeds up to 3x faster than standard TPU filaments (80-120mm/s) while maintaining excellent print quality and dimensional accuracy.

Professional Black Finish: Deep, consistent black color provides a premium appearance ideal for consumer products, automotive parts, electronics enclosures, and industrial applications.

Easy Printing Performance: Excellent flow characteristics and clog-free operation work reliably with most FDM printers, making flexible printing accessible to users of all experience levels.
