Eolas Prints TPU pellets are 100% virgin, dye-free thermoplastic polyurethane in granule form for pellet-fed 3D printers. With a Shore 93A hardness rating, these pellets sit in the semi-rigid range of the TPU spectrum — flexible enough to absorb impact and compress under load, firm enough to hold geometry and resist permanent deformation. They are the pellet-format equivalent of standard TPU filament, with the cost and throughput advantages that pellet-fed printing provides at volume.

Shore 93A — What It Means in Practice

Shore A hardness measures the resistance of flexible materials to permanent indentation. At 93A, this TPU is on the firmer side of the flexible spectrum — comparable to a shoe sole or a firm rubber gasket. It bends and compresses under manual force but springs back cleanly without permanent deformation. For comparison: a standard eraser is around 60A, a car tyre tread around 65–75A, and a hard hat liner around 90–95A. Applications that suit 93A TPU include phone cases and protective covers, flexible hinges and snap-fit enclosures, anti-vibration mounts, wearable device components, and any part requiring impact absorption with dimensional stability.

Processing Notes

TPU requires dry pellets — moisture in the material causes bubbling and stringing during extrusion. Store in sealed bags with desiccant between uses and dry at 70–80°C for 4–6 hours before printing if pellets have been exposed to ambient humidity. TPU prints best at moderate speeds on pellet-fed systems; too high a throughput rate can cause inconsistent flow with flexible materials. Direct-drive screw extruder configurations handle TPU significantly better than Bowden-style pellet systems. For tuning help, see our PETG, TPU & ASA settings guide; new to pellets?
