I have a question about retaining the structure of a material. I'm working on a project at the moment and I was wondering if there are ways to laminate cylindrical objects through a desktop laminator. The key idea is for it to remain cylindrical after lamination. I've tried inserting some materials inside and around the cylinder object to help it maintain its shape after lamination. This has had some success. I'm wondering if there are any other ways to achieve this or any methods that produce better results. Please provide input with a straw as an example and provide results (i.e., proof via photos, etc.). I know there are shape memory polymers out there. What is a simple way to fabricate it or acquire it?
