Convert Your IGS CAD Files to 3MF

Our free and fast tool will convert most IGS (Initial Graphics Exchange Specification) CAD files to a standard 3MF (3D Manufacturing Format) 3D model file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple IGS files; up to 25 files at a time can be converted.

To convert your IGS file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a 3MF file and will be ready for download shortly afterwards. For more information about the IGS to 3MF conversion process, see the conversion information section below.

IGS is an open file format used within CAD applications as a means of saving data in a format that can be opened and edited in other CAD applications. Its roots can be traced back to the mid-1970s, when it was used by the United States Air Force.

The format itself is a human-readable text-based format and contains data that can represent many different CAD elements, such as points, lines, arcs, and much more. IGS files can be opened with many modern CAD applications, such as FreeCAD.

3MF files are a modern 3D file format designed specifically for use with 3D printable models (additive manufacturing). It was designed to be the successor to the popular legacy STL format (also a common format in 3D printing) to overcome the limitations of that format.

The format of 3MF files is XML-based and compressed with standard Zip file compression, resulting in small, easily transferable files. The format supports 3D meshes along with associated materials and textures, all contained within the Zip file.

3MF Notes

3MF files support material and color information. If your uploaded model contains color information, our tool will attempt to save this in the 3MF file at the end of the conversion process. Textures are supported and will be included in the final 3MF file.

Supported Features

  • Mesh geometry
  • Face and vertex colors
  • Textures
