Home made PLA and PLA+ Strong Adhesive
I need an strong way to bond PLA+ parts for my last project, a fully printed Electric Car (More info here: https://www.youtube.com/playlist?list=PLJfG3HktqdD5y3SG_rDiSx5rBmsbD77oQ)
And I managed to design a glue for PLA plastic that actually creates stronger bondings than epoxy ones.
More than a glue is a chemical welding product. It is made with a solvent (Dichloromethane) PLA as filler.
It really works well in PLA, PLA+ and PETG but need some more testing in this last one.
I am now working in the proportions (Filler/Solvent) in order to get the best results and easy to use. I will make a short of a manual of how to make it when finished.
Hope this helps to others.
Made a vido comparing different bonding systems:

So it is similar to 3D Gloop?
Yes, I suppose so. I do not know what solvent/s they are using but I suppose that it is Dichloromethane or maybe Trichloromethane.
But it is actually different, Gloop is very thin almost like if it was solvent only.
I was able to try it some time ago and it cures/dries very fast, and produces very strong bondings, I believe as strong as this home made glue or CA (Runout of it before I made the video...)
But that fast curing speed makes it not usable for my project;
What I mean is that the parts are quite big and it dries up before I am barely able to apply it to both parts surfaces to be bond. Also it happens that as soon as the surfaces get in contact they weld so strong that is imposible to reposition them in the case of misalignment. (Similar happens with contact glue or CA)
The one I made is slower. It also quickly creates a strong bond but it takes some minutes to do so, then it is posible to realign parts if necessary, the parts can be handed in a few minutes, but it takes some hours to fully dry. So it is easier than Gloop to use for me in this project.
