eSUN eLastic (TPE-85A) is a flexible 3D printing filament produced by eSUN. It is designed on the base of Thermoplastic elastomers then mixed with hard plastic. It is characterized by a high level of elasticity, while the 85A identifies its shore hardness. This means you can stretch and flex the material without the risk of breakage.
Non-toxic and highly flexible, eSUN eLastic grants good impact resistance and a dimensional accuracy of up to 0.05mm. It comes in a natural white shade resulting in a soft matt finish. It can be printed on any FDM 3D printer preferably equipped with Direct Drive extruder. Printing at a low-feed rate is strongly suggested to achieve optimum print results.
eSUN rubber-based filaments are commonly used to produce objects with a high degree of flexibility, such as wheels, smartphone covers, shoes, insoles, and many more. eSUN eLastic features a uniform diameter of 3mm (2.85mm) and comes coiled around clear spools of 1kg.
