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.
STL Converter Capabilities
Our STL converter can both convert from and to STL files and our developers are working to improve our STL conversion tools in future versions.When converting 3D Model/Mesh files using our STL converter we will attempt to convert color materials into a suitable format for use in the converted file.
Our STL conversion tool can convert most 3D geometry including mesh vertices and faces with no loss of detail. Any color materials contained within the 3D model file will be converted where possible.
No, due to the different methods of assigning textures to a 3D model textures are not currently supported. If your STL model contains textures or references to external texture files, these will be ignored.
Yes! Our STL conversion tools are 100% free to use.
No, you can convert as many files as you wish. We do not impose any conversion limits on our STL conversion tools.
We aim to process all STL conversions as quickly as possible, this usually takes around 5 seconds however this can be longer for certain files and significantly longer for some larger file formats, so please be patient.
Once your STL file has been uploaded and we know the file format you wish to convert it to our bespoke conversion software will convert your STL and make it available for you to download with a unique download Url.
Yes, of course it is! Your STL, once converted is deleted 1 hour after upload and the download link will expire after this time.
Yes! Our STL conversion tools will run on any system with a modern web browser.
If you are having difficulty converting your STL you can contact us and we will try to help where possible.
