People find polyurethane more convenient (i.e. Original Gorilla glue). I guess it is more convenient comparent to mixing the two exposy components. It dries in 1-2 hours and cures in 24 hours. It will also work for PLA.
Cyanoacrylate can be used, but tends to be brittle. I see reports of trouble using it with PLA
