Description
The eSUN eFlex TPU is a high-performance, transparent, and soft elastic material designed for advanced 3D printing applications. Often referred to as “soft PLA,” this professional-grade TPU (Thermoplastic Polyurethane) boasts high flexibility, exceptional mechanical strength, and superior resistance to wear, aging, chemicals, water, oil, and solvents.
With a Shore A hardness of 87A, eFlex is engineered for durability, offering waterproof, cold-proof, and anti-ultraviolet properties. It is an ideal choice for creating functional flexible parts, seals, gaskets, and protective casings. Note: Because this is a soft/flexible filament, please ensure your 3D printer’s extruder setup is calibrated and capable of handling flexible materials to ensure a smooth and successful print.
