My right side of my bumper was off it’s broken when I got my accident what can I used to put it together …? I try the epoxy but didn’t work
Epoxy does not work on many plastics. Your best action would be to replace the bumper cover. A quick look online found them under $100.
Some will paint them for you.
If you still want a temporary fix, you may need to use a metal strap with bolts or screws. Then there is alway duct or gorilla tape.
3D printer solution of the problem
I suspect 3D scanning of the area and printing of a patch might be as costly as replacing the bumper cover.
BTW, those prices were aftermarket. New from Toyota appears to be less than $300.
It would be great if you could post some pictures
