There are a lot of considerations here. Nozzle size and material are the biggest considerations. I have used tungsten carbide nozzles with apparent good results, it printed PLA+ as good as brass. However, I did have clogging issues when printing with carbon fiber Nylon, I think that the rough internal surface catches the fibers. I have better results with the E3D NozzleX, though they conduct heat more slowly and can’t print PLA+ quite as well as brass, but they still do fine. 0.4 MM nozzles are a good all around option, but a 0.5 MM nozzle will clog less with carbon fiber Nylon while still maintaining detail. My newer lower designs are optimized for using 0.5 MM nozzles, be sure to check the README to see if the design is compatible.
