A phone case wants a hardness the spool actually publishes. These comments do not choose one. [Flexible filament](/answers/flex), [TPU hardness](/answers/tpu_hardness), and [shoes](/answers/shoes) are the pages with the grade and the print setup. The table is shore 85, shore 90, and a 95A name. It is not a drop-test ranking.
## The hardness that is stored

[Bambu TPU 85A](/brand/bambu-lab/tpu-85a) lists 200–250 °C (392–482 °F), a bed of 30–35 °C (86–95 °F), drying at 70 °C (158 °F) for 8 h, and shore 85. [Bambu TPU 90A](/brand/bambu-lab/tpu-90a) lists the same nozzle, bed, and dry cycle, and shore 90. [Prusament TPU 95A](/brand/prusament/tpu-95a) lists 220–240 °C (428–464 °F) and a bed of 55–75 °C (131–167 °F). The shore field is empty. Drying at 60 °C (140 °F) for 6 h is the Prusa material default, not a figure this page copied off a 95A impact test.
