3D printable river system. The SLT file can be printed on many 3D printers. Personally I have printed it on a Sovol Printer. It takes approx 8 hours to print. Once printed you can paint it, add LED lights etc, to make it more interactive.
When designing a 3D-printed river model, remember that rivers increase in size and volume as they flow from their source to their mouth.
LED light points
- Source - near the top of the model - mountain and glacier.
- Waterfall - near the second drop in the river system.
- Tributary - to the right of the model
- Lake - right side of the model
- Flood Plan - center of the model
- Delta - near the front, raised piece of land
- Mouth - near the front center
- Ocean - near the front left of the model.
They always flow downhill due to gravity, taking the path of least resistance. This causes rivers to meander (bend and curve) around obstacles like rocks and hills. The river’s flowing water erodes the land, forming features such as waterfalls, valleys, and gorges. Further downstream, as the river slows down, it deposits sediment, creating features like oxbow lakes and deltas. These elements can be modeled in 3D to show how rivers shape the landscape over time.
