A material set that can be used for making high aspect ratio lines includes a sacrificial feedstock comprising an organic polymer, a solvent, and one or more optional additives, and a functional material that forms a ribbon with the sacrificial feedstock without the sacrificial feedstock and the functional material substantially intermixing, wherein the sacrificial feedstock has a yield strength of greater than about 100 Pa or a viscosity of greater than about 104 cP at a shear rate of less than about 10 sec-1 to enable the ribbon to maintain structural integrity, and the sacrificial feedstock can be removed from the ribbon, leaving the functional material in place with an aspect ratio of greater than about 0.3.
