To change the filament color, simply pause the printing process, remove the current filament and replace it with the desired one. You need to know at what layer you're going to switch filaments - for that, enter your 3D software of choice, in my case "Cura2," segment the design, then go to the preview mode, where on the right-hand side a bar will appear allowing you to scroll down and see how each print layer is being made.
