I'm wondering which plastic would be best suited to sunlight exposure, and not deform or distort. The mechanical stability in most important but continued UV exposure is also a consideration. Discoloration is not a real concern.
None of the detail plastics are suitable, they are set with UV and continue to be UV sensitive. So far my WSF prints are holding up very well to abuse and exposure, but admittedly I haven't left any of them out in the elements yet.
