One more time I’m testing another carbon fiber reinforced filament. After Colorfabb’s XTCF-20 and Fiberforce Nylforce Carbon arrives the PETG carbon fiber from “technologyoutlet”. My first print, just five minutes after openning the spool bag, was a mini vice. I used the same parameter as for nylforce carbon, 240°C, heated bed at 70°C, 60mm/s with a 0.4 nozzle (E3D V6 hot end) This filament it’s not good for high detailed parts due to the rough surface finish but the prints are really strongs. If you are looking for a quality material to print fuctional parts, any one of those could be your choice.
