Soldering PLA together? Will it work?

[TheOrganist]

I use a soldering iron all the time to join PLA together and it is STRONG, what I do, is, I get a small length of filament and u(s)e that as a kind of solder. SO you put the filament on(l)y the area you want to join, put the soldering iron to it and just follow it down where you want the join. It is very strong and sturdy too.

If you are fusing parts together that are printed in PLA... You should consider using Weld-On #4.

I use it all the time to glue (FUSE!!!!) PLA parts together.

I remember using this stuff in the sign making trade, we used a syringe to apply it. But using a soldering iron works well too.

This might be a good application for one of those "3D printing pens" - which are actually more like 3D drawing pens that spit out hot plastic.

Has everyone forgotten where the filament for 3D printing originally came from? It was first made as the fillet for plastic welding, the plastic was softened by a hot air blower which later gave rise to the reflow tool used for smd circuits.
