3D model description

This is Greenland with and without the present day ice sheet. The ice sheet and bedrock topography come from etopo1, see also http://www.ngdc.noaa.gov/mgg/global/relief/ETOPO1/data/

3D printing settings

Same as my other relief maps, the DEMs and the STL generation software is public domain as far as I know. To print this model you have to tell your gcode generator to completely fill in everything in the model. This is the difficult part of printing the model:

First attempt I tried to trick slic3r but it left holes in the model

Second attempt I used Cura with a 25% fill-in. Perhaps it needs a little bit thicker walls, total print time: 5h 50min. I only get to see the printing defects after many hours.

Third attempt, back to slic3r and change the option to fill-in a full layer for every so many (20) layers printed, and that tricked the fill-in algorithm to reach the roof of the model which is what you need.
