The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.

The ZIP file is one of the most common types of compressed file types available and is widely used to compress any file type and give great compression results leading to smaller file sizes. ZIP files were originally released in 1989 and over time the format has received many revisions.

ZIP archives can contain any number of folders and files and can use many different compression algorithms to perform the file compression, though DEFLATE is the most common one in use. The format has built in support in many operating systems including Mac OS and Microsoft Windows.
