Modeling Topography and Erosion with 3D Printing by roberthemlich

Last crawled date: 3 years ago
"Modeling Topography and Erosion with 3D Printing" is a project that will demonstrate the effect of river erosion on the Grand Canyon. This model will act as a visual aid for studying geography and earth science.
The included 3D printable files will allow students to create a scale terrain model of this region and all the accessories needed to simulate a water source.
By using rigid plastic PLA to print the Grand Canyon and water soluble PVA to print a River Valley that fits within, water poured through the river will dissolve the PVA and gradually expose the canyon underneath. During the experiment, participants will observe natural formations that will appear and identify geographic terms to understand how and why these structures come to be.
Update #1 - 4/12/2018: I have uploaded an experimental two-part mold for the PVA river, in case you would like to cast the river insert out of a different material (or from liquid PVA). This is still in the very early testing phase, so please use at your own risk. The mold has four mounting holes for standard M3 (x12mm or longer) bolts.
Update #2 - 3/28/2019: Included in the files now is a text document which goes into the details of exactly how I made the Grand Canyon and PVA insert in Blender 2.78. If you are an advanced user and would like to try to make your own topographic model, be sure to check it out.
Update #3 - 6/27/2019: The source Blender 2.78 file used to make all the terrain model pieces is available in the files now. This includes the original geometry, the starter river shape, a blank PVA insert (before the river was booleaned), and boolean cubes which can be adjusted to make a new insert or deeper river. For people who don't want to manually program the color changes, there is a Grand Canyon model separated into 6 colors in the file too. In the Thing Files, the raw geometry of the starter river, an extruded starter river for booleans, and the blank PVA insert are uploaded for making custom molds for new erosion substrates.
Feel free to share any images, videos, tips, tricks, or suggestions from your experiment and experience with the project!
