Automated three-dimensional (3D) printing work flow through a network is provided. A network server receives through the network a request to convert 3D segmented medical image data to information print-ready for printing on a 3D printer. The 3D segmented medical image data is converted to a converted data file in a medical image data file format that allows multiple sub-segmentation of a particular human anatomy or region of interest. The medical image data file format allows for storage of mask segmentation information. Identifying information, including patient information, is removed from metadata of the 3D segmented medical image data when converting to the converted data file.
