From the words of the project creator :  "The SMuFF (Smart Multi Filament Feeder / Extruder) is a highly scalable tool for multi-color / multi-material 3D printing...."  

From me : the SMuFF is an incredible project that allows you to enhance any 3D printer and is also an incredible community of users and makers ready to help and improve each other.
