As per my other space based prints, used Rhino3D, used the heightfield heightfield command to convert an grayscale converted image from laser altimetry data (http://www.nasa.gov/images/content/565693main_lroc_wac_dtm_tycho.jpg), converted the heightfield to a mesh and applied it to a box structure to give it some height. Printed on a Replicator. Some warpage in my print (there is still a weird issue with slab like prints on the platform not sticking well).
