Blister pack material choice?

[Andrew_W 8]

What would be the most suitable to printing prototype blister pack packaging that has a flexible hinge on it? PP, TPU95? Colour or transparency is not important as we're just checking for fit and function.

I think that is way to thin to print with FDM, and you will not get the material properties you are after by directly printing this. What you could do is use FDM printing to create prototype formers for vacuum forming (eg https://mayku.me/formbox)

I ended up using UltiMaker Polypropylene Natural for my prints.

 

Images of a section of the part printed to check for function and fit. Wall section is 0.5mm. I had to use a gyroidal support pattern of 80%, and also a support interface for roof and floor. The default zig zag support didn't work where the paths crossed over each other due to the material being so soft that the crossing layer pushed the lower layer out of position.
