Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large amounts of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth’s surface is made up of the ocean, dwarfing Earth’s polar ice, lakes, and rivers. The remaining 29% of Earth’s surface is land, consisting of continents and islands. Earth’s surface layer is formed of several slowly moving tectonic plates, interacting to produce mountain ranges, volcanoes, and earthquakes. Earth’s liquid outer core generates the magnetic field that shapes Earth’s magnetosphere, deflecting destructive solar winds.
What can I use a 3D model in STL format for?
STL model of Earth can be used for various purposes:
- Making physical models from plastic or photopolymer using 3D printers
- Making models of wood or metal using CNC machines
- Making a high-resolution relief using 3D laser markers
- Making of “master forms” for duplication of products using foam polystyrene or concrete
- Creating computer graphics
- Creation of low-polygonal models for computer games
What is the resolution of the 3D model of Earth?
With the development of technology, it is becoming possible to produce more and more precise relief models.
For example, there are 3D printers that can print models with a layer height of 0.16 mm, 0.1 mm, 0.05 mm, or even less. These devices require high-quality models. But a higher-quality 3D model contains more polygons and has a larger file size. One of the challenges is to find a compromise between the file size of the STL model, which would be convenient to work with, and the desired quality of the finished product.
The 3D model of Earth has a fairly large size and many polygons.
