• After designing a model in a CAD program, the model need to be saved as an STL file
• STL is the standard file type used by most or all rapid prototyping systems.
• The STL file approximates the surfaces of a solid model with triangles
• The number and size of the triangles determine how accurately curved surfaces are printed. The more complex
the surface, the more triangles produced
