STL is a file format native to the stereolithography CAD software created by 3D Systems. [3] [4] [5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography, [6] although it is also referred to as standard triangle language or standard tessellation language.
The lack of support for complex data like color and materials means that STL files are best suited for basic 3D printing tasks. Additionally, because STL files use an approximation of the model's surface, a printed STL file may be inaccurate compared to the CAD geometry, and high-resolution models can result in very large file sizes.

The STL was created as the first library of generic algorithms and data structures for C++, with four ideas in mind: generic programming, abstractness without loss of efficiency, the Von Neumann computation model, [2] and value semantics. The STL and the C++ Standard Library are two distinct entities. [3]
Standard Template Library, originally for the C++ programming language.stl, a file format for subtitles; STL (file format), a file format for 3D CAD models; Statement List, programming language for Siemens SIMATIC S7
The time required for printing a completed part from a data file (.stl or .obj) is calculated as the sum of time for the following stages: Pre-processing stage, which spans the preparation process of both part and printer. This is required before the actual printing starts.
Model-based definition (MBD) is a method of product specification using elements within 3D models as defined by ASME Y14.41-2012. ASME Y14.41-2012 is based upon ASME Y14.5-2009 symbols and definition methods, such as Geometry Dimensioning and Tolerancing (GD&T).

Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.
