Nylon CF is one of my favorite filaments to print with. It’s tough, durable, and prints accurately. This stuff is stringy so I use coasting in the settings and it helps to dry the filament in the oven or a filament dryer. I dry this filament at 70°C for a minimum of 12 hours before printing. A 230°C print temperature is fairly low for nylon CF so feel free to boost that up. I print at 260°C for functional parts and 230°C for low stress parts and quality surface finishes.
