You will need to use slicer software to convert the STL file to G-CODE, a plain text script that tells a 3D printer what to do. Note: The STL file cannot be used to proceed with 3d printing right away. Some 3d printers also do not support high resolution, so even if you set up a high-resolution STL file, the machine will not be able to handle it. However, it should be noted that the more triangles are used, the larger the size of the STL file will be.

The greater the number of triangles, the smoother and more beautiful the surface of the object will be. The number of these small triangles acts as the resolution of the model. The model surface in the STL file is created by linking many small triangles. STL is an acronym for “Standard Triangle Language” or StereoLithography. If you are involved with 3d printing, you will be very familiar with the STL file format.
