Technical data sheet, drying checked 18 October 2026, lists a nozzle of 200–250 °C (392–482 °F), a bed of 30–35 °C (86–95 °F), and drying at 70 °C (158 °F) for 8 h. This catalog stores shore 85. The phone-case comments do not compare 85 with 90. | |||||

A phone case wants a hardness the spool actually publishes. These comments do not choose one. Flexible filament, TPU hardness, and 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 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 lists the same nozzle, bed, and dry cycle, and shore 90. 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.
Pros and cons
Pros
- Hardness stays on the row that publishes it.
- The jokes stay jokes. They are not rewritten as a material test.
Cons
- No comments names TPU, PLA, or a brand. A best-case ranking would be invented.
Printer considerations
- Shore 85 and shore 90 are catalog fields on the Bambu rows. 95A is a product name on the Prusament row.
- The Bambu bed stops at 35 °C (95 °F). Prusament's bed starts at 55 °C (131 °F). Those beds are not interchangeable.
- They do not say TPU.

Questions
So is 95A the phone-case grade?
Not from this batch. Prusament TPU 95A puts 95A in the name and does not store a separate shore field. Bambu's stored fields are 85 and 90. TPU hardness is the grade page. Flexible filament is how TPU prints. Shoes is the other flex-against-a-body question. None of the comments here picks a grade.
Did anyone in the comments actually name a case material?
No.
