Information about STEP and STL file formats

Name STEP STL
Full name Standard for the Exchange of Product model data Stereolithography File Format
File extension .step .stl
MIME type
Developed by ISO 3D Systems
Type of format
Description STEP is a neutral file format that allows the transfer of files between different CAD softwares. The development of STEP started in 1984 as a successor of IGES, SET and VDA-FS. STEP format (Standard for the Exchange of Product Data), is an ISO standard exchange format It is used for representing three-dimensional data in a format that can be recognized by multiple programs. ISO standard number: 10303. STL is a file format native to the stereolithography CAD software created by 3D Systems. This file format is supported by many other software packages. It is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact.
Technical details STEP formats can be used to exchange data between CAD, Computer-aided manufacturing, Computer-aided engineering, Product Data Management/EDM and other CAx systems (Computer-aided technologies). STEP is the same as STE and STP. The disadvantage is that a STEP file is not editable and the design tree of the model is not available either. An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced and negative coordinates are commonly encountered in STL files today. STL files contain no scale information, and the units are arbitrary.
