Creality K1 Filament Settings After fiddling about so I could use my esun silk filament I discovered you can down load the correct settings for my printer from esun website then import them in to the printer to get perfect settings every time. So you can use any filament in your K1. I did notice that Creality Hyper is not the only high speed filament the K1 can use for fast speed printing just need the correct settings.
