eSUN eLastic TPE-83A
Product Description
eSUN eLastic TPE-83A is a high-performance flexible 3D printing filament with a Shore hardness of 83A, offering an excellent balance of softness, elasticity, and durability. Compared with TPU-95A and eFlex materials, printed parts are noticeably softer and provide a smooth, skin-friendly touch with reduced surface friction.
Its matte finish, high elasticity, and outstanding toughness make it ideal for applications requiring flexibility, impact resistance, and long-lasting performance. Whether used for wearable products, protective covers, grips, seals, or soft-touch prototypes, eLastic TPE-83A delivers reliable results with excellent resilience and comfort.
