title: Matlab patch - 3D printing format with color
body: <blockquote>
    <p>Has anyone had experience in exporting Matlab coloured patches to STL or another format that can be used for 3D printing?</p>
  </blockquote>
  
  <p>I have a mesh with values associated to each point of the mesh. In this way I can colour the surface and obtain something like in the figures below. I would like to try and print a colour 3D model corresponding to the mesh with the colors. However, I did not manage to use any of the available tools on the Matlab file exchange in order to do this. No matter what I do I do not manage to get the color information in the file. </p>
  
  <p>Do you have any suggestions regarding which format I could use to store the mesh with colours attached to vertices so that the resulting file could be used by 3D printers?</p>
  
  <p>Here's an example of object I'd like to print:</p>
