Overall modular workflow described in the text for A. Transforming 2D images to 3D models and B. Desktop 3D Printing brains and skulls.

We highlight, in each table cell, software or hardware that we have found produces reliable prints, noting the slight variations in our workflow process for MRI based brain models compared to CT based skull models. The modular nature of the workflow process allows for alternative methods to be used at each step. Each step and potential alternatives are described more thoroughly in the text. Step A4. Crop 3D model is italicized because this step is optional, primarily for use when one only needs to print a subset of the organ of interest.
