Abstract: A system for producing an audio file comprises a non-transitory computer-readable medium with instructions stored thereon, that when executed by a processor perform the steps of converting an additive manufacturing design file to a text-based file, converting the text-based file to a series of binary values, converting the series of binary values to a series of integers, calculating a normalization factor for the series of integers, dividing each of the series of integers by the normalizing factor to produce an array of floating point numbers known as the design string, multiplying the design string with the normalizing factor and comparing the resulting arrays with the original array of integers to generate the error string, converting the design string to an audio file, and converting the normalizing factor and the error string to a text file. Systems for verifying the authenticity of, identifying, and compressing AM design files are also described.
