Rigidity of Thermoform
Quote from Hengyi Jiang on 2022-01-07, 00:10:20Hi,
Has anyone been successful with other thermoform materials that is rigid?
I've tried PC up to 0.8mm but i realise that i start losing details. Same with PET 0.8mm though more details i lose rigidity.
Not sure if i should try acrylic or other materials.
Thanks!

I do not recommend the use of acrylic because it is more tough than PC, and therefore you will lose more details. I would suggest PETG. I did form 3.0mm PETG and got a great result.
