How to glue PLA plastic together?

How do I glue PLA plastic together?

Crazy glue
Epoxy
Correct kind of Plastic Cement
3D Printing pen
Piece of PLA filament in Dremel tool

I use uhu all purpose clear glue.

Solvet based and as well as glueing I reckon the solvent does a little dissolving as well.
Makes a really strong bond anyway :-)

Super/crazy glue I find is too brittle.

print pen is a bit awkward.
Not sure how ytou'd glue the middle of a piece with a dremel ?

From searching the Internet, I found out that there are many ways of gluing PLA plastic pieces together. Which uhu all purpose clear glue on Amazon.com in USA?

I use this: http://www.ebay.com/itm/SCIGRIP-4-Ac...0AAOSwpRRWoJ8g

It is a solvent that melts the two sides together.

We use either epoxy or an all purpose contact adhesive.

Something like standard UHU or UHU Por works very well.

I tried everything.

This is the only thing that worked....at least for my applications. I needed a VERY strong permanent bond.
This stuff melts a thin layer on both parts, fuses the melted plastic together then hardens. Once done it's one piece. Cannot separate.

I have been using Loctite Super Glue Professional Liquid and it worked. I'm trying to find lubricants that is compatible with plastic and plastic putty. Any suggestions?

Very nice, it makes me understand more.

This is what I use. It fuses the pieces together and is very strong.
