to follow up on this. i did get the replacement spool of copper filament from reprapper quite a while ago. its just been sitting here until now. i havent had a chance to try it with anything. the extrusion of the new spool is right on the money and smooth unlike the picture i posted before. the stuff prints great. no jamming or clogging from the particles. i printed this twisted star vase for someone. the stuff prints super clean and has a really nice look. the metallic in it really shows off the polygons in the model which is actually kinda cool.

Very nice! That one looks like it was worth sticking with.
