I justed 3d printed a boat and glued it together, however it warped in the sun. I was using PLA filament. Does anyone else know of a strong, and heat (UV) resistant filament that I could use. My printer can print almost any filament so i need suggestions.
I would try ABS or PETG, both of which have higher glass transition temperatures than PLA and are common filament types. Although it should not warp in the sun, ABS (not sure about PETG) is prone to warping on the print bed so a heated bed is a must.
