I have a DEM in ArcGIS 10.1 that I would like to get into STL format for a 3D printer. Does anyone know some software that will allow me to make this conversion?

I have to use the STL format because that is the format required by my university's 3D printer.

I think Global Mapper will be perfect solution for you. Please check this page for details and go through STL commend details also

You can check this link also for second alternative (Some commercial tool is available)

I am going to mark this as the best answer since it worked. Converting using Global Mapper was pretty dang easy. But, I wish there was a free/open source equivalent. Additionally, I was not able to print out the surface due to the printer being too small. –  jwx Apr 20 '13 at 22:35
