Making your own filaments

[Kingoddball]

I have never done my own filament but always wanted to out of water/coke bottles (PET IIRC).

I was looking at using something like;
http://www.filabot.com/
(plus some on thingiverse)

But in the end I didn't buy and wanted to build something (reprap style!) but laziness beat me and I stopped

On a different but related note; Pellets/RM! (Raw Materials)
Have you looked at this?

Rich has built an extruder which uses raw pellets.

Printing in RM will require similar heat to filament, but its a very different printing medium (method?) and for me I'd be worried about extruding air bubbles.
