Before creating an STL file and G-code file in the additive manufacturing process, it is essential for engineers or operators to create a 3D CAD model of the part. The STL (Stereolithography) file format is specifically used to represent 3D geometries, and it is generated directly from a 3D CAD model. The CAD model serves as the digital blueprint for the part, detailing its shapes and dimensions in a format that additive manufacturing systems can interpret.

Once the 3D CAD model is complete, it can be converted into an STL file, which prepared for slicing into G-code, a language understood by 3D printers. This conversion process ensures that the printer accurately reproduces the design as intended. Without a properly designed CAD model, the STL file cannot accurately represent the geometry needed for successful manufacturing.
