In an embodiment, there is a method of preparing a conductive ink formulation. The method can include dissolving a stabilizer in a first solvent, adding a reducing agent to the first solvent, adding a metal salt to the first solvent and forming a slurry by precipitating stabilized metal nanoparticles in the first solvent. The method can also include forming a wet cake of the stabilized metal nanoparticles and adding the wet cake to a second solvent. The second solvent can include at least one of a polyvinyl alcohol derivative. The wet cake may not be actively dried prior to being added to the second solvent.
