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?

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