This is a 3d topo map of the south corridor area of the Grand Canyon of the Colorado River. This map covers the area of the Village, Phantom Ranch, and the South Kaibab and Bright Angel trails.
The sample was printed using Prototype Supply PLA on a Printerbot Metal Simple. The print was finished with oil-rubbed bronze color Rustoleum spray paint and dry-brush highlighted with silver Guilder's Paste.
We talked about this finishing technique and a whole lot more about 3d printing on the 3D Printing Today podcast available on iTunes, Stitcher radio or direct from the source at http://threedprintingtoday.libsyn.com/
