"research seeks to loosen the bottleneck by exploring the relationship between 3D-printing process parameters and nanomaterial morphology in nanocomposite printing inks... uses carbon nanotubes (CNTs)—known for their high tensile strength and lightness. This revolutionary ink could replace epoxies... junction of material type and morphology—size, shape, structure—in polymer nanocomposite inks is the ultimate in form meeting function...
