A method (200) for depositing an aluminum film or contact (124). The method includes providing (230) a substrate (120) with a surface for receiving the aluminum film (124). The substrate (120) is heated (240) to a printing temperature such as over C., and the method (200) includes depositing (250) a volume of ink upon a surface of the substrate (120). The ink (136) includes an organometallic aluminum complex or precursor, and the substrate surface temperature is selected or high enough to decompose the organometallic aluminum complex or precursor to provide aluminum of the film (124) and a gaseous byproduct. The depositing or printing (250) of the ink may be performed within an inert or substantially oxygen-free atmosphere (144). The ink (136) may be a solution of the organometallic aluminum complex and a solvent. The aluminum complex or precursor may include an amine compound and alane.
