Polymaker PA6-CF Nylon Filament 1.75 Black Carbon Fiber Nylon Filament 1.75mm 2kg Spool - PolyMide PA6-CF Warp Free Nylon 3D Printer Filament

Working on Freeskate trucks with PA6-CF requires intensive experimentation with different filament makers, design, and print settings. Polymaker has outperformed 4 other manufacturers in respect to the most important mechanical properties for this application with is ultra demanding in torsional, tensile, and impact strength. In the photo above, Polymaker is the smoother cleaner print on the left, printed at 292 degrees with a .4 hardened steel nozzle with .16mm layer height, 2mm retraction, 60mm/s speed. It's ultra critical to have your filament enclosed in a heated chamber or dessicant box while printing, and keep your nozzles clean between every 8 prints or so. You can flame a hardened steel nozzle with a MapGas torch without damaging it. The other filament makers like Esun or Sainsmart have not achieved the level of smoothness and stength that Polymaker has. Sainsmart truck plates cracked and delaminated after blunt impact testing of the skate. I will be working with Polymaker for years to come as long as they do not change their formula like Sainsmart recently did, lowering the CF content to make parts look nicer, but perform much worse.

Dont buy this junk, they dont have the template files for 3d printers. cant use it
