FLEXIBLE
TPU 64D
A high-hardness thermoplastic polyurethane used for durable FDM parts requiring rigidity, impact resistance, wear resistance and controlled flexibility.
Material Overview
TPU 64D is a high-hardness thermoplastic polyurethane that bridges the gap between flexible elastomers and rigid engineering plastics. It provides substantially greater rigidity than soft Shore A TPU grades while maintaining a degree of elastic deformation and impact absorption. The material is suitable for industrial components exposed to wear, repeated loading, oils, greases and demanding mechanical service. Final performance depends on the selected formulation, wall thickness, infill structure, part geometry, print orientation and production parameters.
APPLICATION
Typical Part Types
Impact-resistant machine components and protective parts
Durable jigs, fixtures and manufacturing tools
Wear-resistant guides, stops and contact components
Semi-rigid wheels, rollers and drive components
Bushings, couplings and vibration-resistant mounts
Protective housings, guards and equipment covers
Clips, retaining components and flexible locking features
Components exposed to oils, greases and repeated handling
Material Selection Note
TPU 64D is suitable when a component requires greater rigidity than conventional flexible TPU while still benefiting from impact absorption, abrasion resistance and limited elastic deformation. It should not be treated as equivalent to soft TPU 82A. Gramm reviews the required stiffness, deformation, loading, wear conditions, chemical exposure, operating temperature, geometry and dimensional requirements before manufacturing.
