Sometimes printing certain objects saves a lot of time (and material) to print them as separate pieces then join them after printing.
In some circumstances, I've been able to design snap clips into my objects so they permanently snap together.
But in many cases, that's tedious or not an option. That's where the ability to BOND or FUSE the objects together would be great.
I've (unsuccessfully) attempted to bond numerous PLA pieces with various "welding solvents", glues and adhesives.
So far nothing has formed a permanent, strong bond. I'm wanting the pieces to fuse together and re-harden as one solid piece.
Here is a short list of the exact things I've tried....
Testors Cement for Plastic Models (Red tube with white lettering)
Of everything I've tried so far, this has worked the "best". But still, with enough pressure, I can always cleanly separate the joints.
The depth of the bond is too shallow it appears.
Plastruct Plastic Weld - 2oz Clear bottle with Orange label
Very disappointed with this product. This is the ONE I had highest hopes for. It seems to wick between joints nicely as it is very thin, like alcohol.
But I believe that is exactly the problem. I think it evaporates so fast that the solvent doesn't have time to sufficiently melt the hard PLA plastic.
The resulting bond is VERY weak and easily broken with little pressure.
Plasti-ZAP - .33oz small white bottle
This product is similar to Crazy Glue.
No luck at all with this product. May not be suitable for PLA plastic.
Worst of all, it smelled the worst, made me cough and I got a headache after using this one.
Does anyone know of anything that will definitely FUSE two pieces of PLA together without destroying the model?
