Yeah - I've just spooled a very generous sample roll of filament that i got from the colorfabb people at the tct show. I have no clue what it is. I 'think' it's pet.
But he didn't say and they were busy so i didn't hassle him. :-)

I've got some proto pasta stainless steel pla, some soluble pva and some 3dxnano pet coming - that's supposed to be conductive.

Fun times :-)
