RANKI Polycarbonate Filament 1.75mm 1KG, Outdoor Use Tough PC 3D Printer Filament, High Temperature Resistance, 1 KG Spool, (Black)

This filament isn't terrible, but it's not good either. It appears to be a PC/PETG blend that's catered to people with printers that can't handle higher end PC blends or pure PC. It blobs worse than most PETG filaments, and it's more temperamental to print than decent PC filament, it's the worst of both worlds.Polylite PC is better than this in every way, it's cheaper, stronger, stiffer has higher heat resistance, and for me at least, it's easier get a decent print.Personally I've had the best results with larger nozzles and layer heights. Nothing under .3mm layer height and .8mm widths prints well for me, not that unusual for a filled filament, but I think the PETG in it exasperates the issue. Really need to slow down the print speed with this stuff, around 30mm/s seems to be the sweet spot to get clean prints without it taking an eternity to print. This can tolerate little bit of part cooling, though that's in a heated chamber, not sure about poorly insulated or unenclosed printers.All in all, this is not worth the current asking price, even the sale price I bought this at is a bit much. I wouldn't buy this unless it was closer to $15-20 a roll.

Great filament. Very easy to print with once you know the correct parameters.I used:Nozzle: 0.6mmLayers: 0.12 - 0.2mm (you can see in some photos how the quality difference is very noticeable, even when its just a flat wall)Nozzle: 250 °CBed: 70 °CSpeed: 50mm/s

I was needing a tough filament for a cantilevered table top extension.I ran it through my dryer (pretty standard for me to do that) and it printed quite nice. No real changes made from using my standard PETG, except I printed near the 250C mark. Also used a 0.6 nozzle to eliminate the risk of clogs due to filament additives. Part came out looking quite nice, with a fantastic feel to it, rock solid and super rigid.I’ll definitely be keeping a roll of this product around.
