Bests & Worsts Reviews from Amazon

Overall, I like this filament. It’s pretty strong, has a nice matte finish, and seems to be consistent through more than 20hrs print time, varying print sizes and types. I’d give 4.5 stars if I could... Patience is key. Be sure to get that 1st layer down correctly, on a well calibrated printer. Also, verify your slicer settings to avoid weak walls or poor adhesion or Layer bonding of perimeters to infill, else the print can crumble easily. A good print will be strong but slightly more flexible than PLA, stiffer than ABS or Nylon. Rigidity is good without being too brittle, or too much flex. For printing quadcopter frame and other parts, some slicer (Slic3r) settings that worked well on my Cartesian are: Bed - 100 1st Layer, then 90-95 (probably don’t even need this much heat, depending on build surface) Hotend - 255-260 1st Layer, then 250 Layer 1 - .35-.4mm (for .4 or .5mm nozzle, respectively) Other layers - .2-.25mm for .4 or .5mm nozzle respectively Print speeds - 40/perimeters, outer at 50%, infill 45, solid fill 20, travel 150, 1st Layer 30 Layer cooling - None Retraction (MK8 direct) 2.5mm, 50mm/s, .8-1.0mm Z hop - no wipe or anything fancy Flow multiplier 1.0 (though I did increase flow rate to 105% on the printer for some prints) Brim - 0 distance, 1-3mm width depending on build surface adhesion Infill - 30-50 is plenty for most printed parts 2-3 outer layers depending on layer height, 3 top and bottom Lastly, make sure the filament is stored in an airtight bag or container so it doesn’t absorb moisture. I still use CF PLA most times for strong prints, but I like this CF PC much better than CF Nylon, PETG, ABS, etc., assuming it passes the test of time. Stiffness between PLA (this CF PC filament is less stiff) and ABS/PETG/Nylon (this CF PC is more stiff). Hope this helps someone save the time I lost with the 1st few prints (basically junk due to not taking the time to fix minor printer and slicer settings).
