This model of Earth is based on a 48K displacement map to show all of the terrain on our globe. It is intended to be used as desk decoration for all Earth lovers & explorers! This is great for showing kids and friends a fun example of the power of 3D printing.
The land masses will be visible when printed in single color or multicolor, because of the terrain - but it really shines as a multicolor print! Both 2 colors or 3 colors work really well.
That being said - the print time gets high when you do a multicolor print, so if you want a quick earth, it is certainly recommend to print as one color. :)
