In the effort to create “multimaterial 3D printers,” the printers often only “allow printing of one material at a time, with limited ability of mixing multiple materials.” In this paper, researchers describe a “new 3D printer which eliminates the above shortcoming by merging the Fused Filament Fabrication and Direct Ink Write in one compact system.”
