Used for the first time today and it went well...after some initial issues getting it stick down the initial layers. Heatbed with clean glass.....thats it ! 260°C print temp, 105°C bed, NO FAN and 0.2 Layers @ 50mm/sec and it printed sweet!

One Tamiya RC Car owner happy with new part! :-)

I kept all my normal PLA settings for this filament and it prints really well at 200c with no heated bed. I honestly didn't expect such I strength increase over standard PLA but for mechanical parts this stuff makes it far more viable to print working prototypes without having to bulk up and reinforce the design so much.

Finished prints have a nice matte look you would expect from carbon fiber with a slightly textured surface, really impressed with this one.
