Yosemite Valley's Cathedral Spires 3dTopo

myminifactory

This is a super detailed 3D topo of Yosemite Valley's Cathedral Spires. The model shines with such incredible detail that you can easily spot the ledge on the classic climbing route on Lower Cathedral Spire. I built it from a LIDAR dataset collected to study nitrogen export and made available at http://opentopo.sdsc.edu/. The LIDAR point cloud was transformed into a 0.5m resolution grid. You can catch my tutorial video at https://www.youtube.com/watch?v=t4-ICkvyJv0. The print took 22 hours to complete. It was sliced with Simplify3d at default high quality settings and printed in PLA on a FlashForge. The print settings included six shells, no infill, and no bottom. Those trees take an enormous amount of time to print. This thing was featured on the 3D Printing Today podcast available on iTunes, Stitcher radio or direct from the source at http://threedprintingtoday.libsyn.com/.
