It does not save mesh topology, which can lead to file sizes larger than can be supported by the 3D printer, and it can introduce roundness errors, which will usually result in a 3D print failure. For example, STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes.
3D printing technology has advanced and offers features and capabilities that STL was never developed to translate. In the years since it’s introduction it has been used by a number of 3D printing technologies, including extrusion and jetting.īut STL is more than 30 years old. STL (STereoLithography or Standard Tessellation Language ) was first developed to translate CAD data into data suitable for use by a stereolithography 3D printer.
