TRex printed with woodfil, the left-hand Tesla logo with Carbon Fiber and the Right-hand one with the Bronze. Just an example of some of the exotic filament types. They work well.
PLA variants?
Yes. All basically print like PLA. The woodfill wants a slightly bigger nozzle but prints OK with a 0.4mm
Bu-bu-bu… The Carbon Fibre filament isn’t going to be strong like true CF, is it? Doesn’t have the fibers intertwined properly???
Correct. It is not 100% CF and the bronze fill is not 100% metal. 60% for the bronze…not sure on the carbon fiber, but still neat 
I’m kinda meh on the cf. Super interested in the bronze, though. What’s the extrusion temp? What’s the finish/weight/feel like?
The CF is actually black (my picture colors kinda suck). The bronze weighs like metal, and feels like metal (once it cools) and the extrusion temp for it is 195-220C (I used 200 – it was fine). You have to let it cool for a few minutes as it is still soft and bendable initially.
