The present invention relates to a method of printing features with an ink comprising a material precursor. In some embodiments, the material includes an electrically active material, such as a semiconductor, metal, or a combination thereof. In another embodiment, the material includes a dielectric. Embodiments provide improved printing process conditions that allow for more accurate control of the shape, cross section and dimensions of printed lines or other features. The composition (s) and / or method (s) improve control of pinning by increasing the viscosity and mass load of the components in the ink. Thus an exemplary method includes printing an ink comprising a metal precursor and a solvent in a pattern on a substrate; Depositing a precursor in the pattern to form a pinning line; Sufficiently evaporating the solvent to form a feature of the material precursor formed by the pinning line; And converting the material precursor into a patterned material.n n n n Patterned conductors, semiconductors, dielectrics, printing processes |
