Guide for Rigidity vs Thickness

I want to give some guidelines for choosing materials for students and I’d like to be able to say for instance “If you want a rigid part in Durable you need a minimum thickness of ___.” We print for a lot of students and they assume everything is going to be rigid unless they choose Flexible which is definitely not the case. Especially with Durable I am finding many prints are coming out very soft. Any guides for this?

This is a bit tricky to make guidelines for because the definition of rigidity can be geometry and application dependent. Have you seen our Flexible Resin sample part? Making a small swatch with different thicknesses like the Flexible Resin sample might serve as a good guide for your students. We also have datasheets and mechanical property comparisons on our Engineering Materials page that you might find useful.
