I apologize if this isn't the most relevant question for this forum but I was hoping someone might know how to repair fractures along layers in a PLA print. I've heard super glue is a good option but does anyone know a method that works well? Thanks!

I use super glue and epoxy to join my PLA prints. You can also use a soldering iron to weld the parts together as long as you can control the temperature.

Ethyl acetate (also marketed as MEK substitute in the US) also works. It dissolves the PLA like acetone does for ABS and works well for re-fusing cracked faces.

Thanks guys for the suggestions. I went ahead and tried the super glue and it seems to have done the trick!
