Once you have mastered the basics of modeling and have become familiar with the software, you can start exploring how to create your own model. You are only limited by your imagination…and the specifications of the machine, material, and printing technique you choose!
This head is made up of hundreds of triangles
The STL format
The STL file format (for STereoLithography) has become the norm in 3D printing. Most machines and modeling software support it.
Such files contain, most often in plain text, the list of triangles (facets) that make up the object with their 3D coordinates (X, Y, Z axes). So, to design a cube, you need 12 triangles as demonstrated in the example below:
