File format information for 7Z and STL

Extension7Z
Full Name7z Archive
TypeArchive
Mime Typeapplication/x-7z-compressed
FormatBinary

A file with the 7Z extension is a compressed archive. It was created by Igor Pavlov in the late 1990s with the intention of making it easy to allow many files to be grouped together and compressed into a single, easy-to-distribute archive.

Along with individual files, the 7Z format allows multiple files and whole directory structures to be compressed and packed into a single container format. The compression algorithm used enables high compression ratios without any data loss.

To open 7Z files, there are several archive processing applications available. Some examples, such as 7-Zip and WinRAR, are able to open 7Z files.

ExtensionSTL

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.

STL files come in two flavours: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.

The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.

Information for converting from 7Z to STL

Our 7Z archive converter will examine the contents of your 7Z file and will look for any 3D model file that it may contain, and this, once found, will be extracted and converted to a 3D STL file ready for download.
