We track 10 eSUN PEBA listings, with prices checked every 4 hours and normalized to a true cost per kilogram. Below is every listing, sorted by price per kg.
PEBA (polyether block amide, often sold under the Pebax name) is a high-performance flexible filament positioned above standard TPU: lower hysteresis, more energy return, and better fatigue resistance under repeated flexing, which suits midsoles, springs, and wearables. It stays flexible down to very low temperatures. It is also harder to dial in than TPU, so it rewards printers already comfortable with flexible filaments rather than a first attempt at one.
