Looks like the stuff of legends :P
Now, if there were any nice colors like Faberdashery's, it would seem to be the perfect filament...
Gotta try it out myself at some point..

I've heard good things about Proto-Pasta but haven't tried their stuff yet

Well I wanted to get some orange nGen to try out and it seems very few resellers here in the USA have nGen yet

I managed to get my nGen samples through today, but before I test it I need to sort out my print head.
I need to strip it down as I'm having a feed problem at startup, and some occasional under extrusion for a few layers. I put a new coupler on last week and with the Spring replacement it's not running at 100% :-(

I have been using some cheap PETG now, and it really is a great answer to ABS. I great the same great surface quality that I never seem to manage with PLA, and it is far tougher than ABS or PLA. It can bend quite far before it breaks. In one case I bent some PETG over 240 degrees, and bent it back and forth a few times and it still did not snap, even though there was a lot of visible damage, of course.

Where do you get the PETG from? Is it possible to chemically polish PETG like ABS with Acetone fumes?

The PET that I use is from Refil http://www.re-filament.com
Temp: 228 degrees, bed 60
Like XT, nylon etc, it is 'sticky', it sticks to the nozzle real easy, leaving burned blobs if you don't remove them.

Is PET and PETG the same? My understanding is that the G in PETG makes it easier to print than pure PET.

The base is PET and 'something' is added to make it easier to print, I guess (not being a chemist..)
The Refil Pet states: 90% recycled PET
100% PET has a higher melting point: 254 degrees
PETGs (or copolyesters) are glycol modified PETs used for injection molding etc.

There are a couple of words about that in the 3D Printing Filament Guide -- but I'm not a chemist either :roll:
