Within the field of additive manufacturing, direct sound printing is limited to a voxel-by-voxel printing. Here, the authors overcome this limitation with a holographic direct sound printing technique in which the information printed part is stored in an acoustic hologram and the printing material polymerizes instantly therefore improving the printing speed and allowing to print multimaterial objects even behind optically non-transparent media.
