Can you provide any guidance on reflective materials we can use?
Sadly, our testing has shown that off-the-shelf mirrors do not have the curvature required.
We have tested many materials attached to 3D printed bases we’ve designed and have had problems with each. For example, some once heated and shaped onto our base are no longer reflective and others we cannot deform enough to fit the curvature.
Looking at last years’ posters that are published in this forum shows very interesting designs, but little insight into the actual materials. For example, one team shares that they’ve used vinyl acetate - but our samples loose their reflective properties once shaped. Other teams simply list that they have formed the reflective material - but do not indicate what it is.
This seems like it is such a simple concept, but our team has been stuck on it for months.
Any advice would be appreciated.
