A metal film for use by an additive manufacturing apparatus is described herein. The metal film has a support structure and metal voxels removably attached to the support structure by respective junctions. When a metal voxel in the metal film is impacted by an energy pulse from an energy source of the additive manufacturing apparatus, one or more junctions that attach the metal voxel to the support structure are broken, resulting in the metal voxel detaching from the metal film (at a desired location in a two-dimensional plane).
