File format information for IGES and STL

Full NameInitial Graphics Exchange Specification
Mime Typeapplication/iges

IGS, which stands for Initial Graphics Exchange Specification, is a widely used file format in the realm of computer-aided design (CAD) and computer-aided manufacturing (CAM). It was developed in the 1980s to enable the seamless exchange of 2D and 3D geometry data between different CAD software systems. The IGS file format serves as a neutral intermediary, allowing various CAD applications to communicate and share complex geometric models without compatibility issues.

IGS files are essentially text-based representations of geometric data, describing not only the shape and structure of objects but also attributes such as colors and layers. These files can encompass a wide range of information, including points, lines, curves, surfaces, and solids, making them versatile for sharing complex engineering and design information. One of IGS's key strengths is its ability to preserve geometry and topology regardless of the software used, ensuring that intricate details of a design are accurately conveyed.

Over time, IGS has been largely succeeded by more modern and capable file formats like STEP (Standard for the Exchange of Product Data) and native formats used by specific CAD software. However, IGES still retains relevance in certain industries and for legacy data conversion due to its wide adoption and compatibility. Despite its limitations in handling advanced features compared to newer formats, IGS remains an important piece of CAD history, playing a vital role in the evolution of data interoperability.

An STL file, short for Stereolithography, is a widely used file format in 3D printing and computer-aided design (CAD) applications. It serves as a standard method to represent the surface geometry of a three-dimensional object. The format was first developed by 3D Systems in 1987 and has since become a fundamental file type in the additive manufacturing industry. STL files are essential in the process of converting digital 3D models into physical objects through 3D printing technology.

STL files consist of a collection of triangular facets that approximate the shape of the 3D model. The surface of the object is divided into numerous small triangles, forming a mesh representation. Each triangle is defined by three vertices in 3D space and possesses information about its orientation and size. Since STL files store only the outer surface of the model, they are often referred to as "mesh" files or "surface" files, as they lack information about the object's internal structure or color.

When using STL files for 3D printing, slicing software processes the 3D model by dividing it into layers and creating the instructions for the 3D printer to build the object layer by layer. Despite its simplicity and widespread usage, STL files have some limitations. They do not support color or texture information, and the triangle-based representation can lead to larger file sizes and reduced accuracy compared to other file formats. Nonetheless, STL remains a vital format in the 3D printing ecosystem due to its simplicity and compatibility with a wide range of 3D printers and software.
