Abstract: A method for three-dimensional printing includes dithering a set surface of the printing object and printing the printing object with the dithered surface. The dithering includes determining the set surface of the printing object, providing a spatially high-frequent dithering signal, and modifying the set surface as a function of the dithering signal. A non-transitory computer-readable medium includes instructions that implement the method. A 3D printing device includes a printing device and a control unit configured to control the printing device using the method.

Abstract: A method is described for selecting voxels for producing a three-dimensional object with an additive manufacturing device. The additive manufacturing device has a building space that is discretized into virtual voxels. The method includes receiving a voxel-based approximation of a surface of the object. The voxel-based approximation includes multiple voxels. The method includes determining, for each voxel of a non-empty subset of the voxels, a signed distance value describing a distance between the voxel and at least one point defined by the voxel-based approximation. The signed distance value of the voxel is determined based on a displacement value describing a topographic characteristic of the voxel-based approximation. The method includes selecting voxels at which material should be added to produce the object. The selection is performed based on the signed distance values of the voxels.

Abstract: A computerized method for filtering a digital audio file to generate an output audio file that induces optimal health and cognitive ability in a listener of a playback of the output audio file is described herein. The method includes the steps of identifying a plurality of target frequencies that span within an octave, identifying a plurality of mid-point frequencies that are situated at mid-points between any two adjacent target frequencies, applying a peaking filter to the digital audio file centered around the plurality of mid-point frequencies to produce highest frequency attenuation at the plurality of mid-point frequencies, and generating the output audio file.
