Introduction to STL Files
STL files, also known as Stereolithography files, are 3D model files used in 3D printing and other computer-aided design (CAD) software. These files contain the surface geometry of a three-dimensional object, represented as a mesh of triangular facets. STL files are widely used in various industries, including aerospace, automotive, healthcare, and consumer products.
📝 Note: STL files are not the same as OBJ files, although both are used in 3D modeling. STL files are specific to 3D printing and rapid prototyping, while OBJ files are more versatile and can be used in various applications.
