Post-Printing

After printing any holes in the model were filled. It was then painted with acrylics and inks to match the colors visible in the HiRISE color pictures of the region. The colors have been exaggerated for artistic effect. Real colors can be seen here.

How I Designed This

The DTM (digital terrain model) image found here was opened in Blender, following the instructions provided here.

I then selected an interesting segment for printing and cropped a 19 x 19cm area, which equals 3 x 3km of terrain at this resolution. The model is scaled 200% in the vertical axis so that the sand dune ripples are visible when printed at 0.1mm layer height. If you wish to print it at real scale, then reduce the vertical scale to 50%.
