File format information for 3MF to OFF

Extension: 3MF

Full Name: 3D Manufacturing Format

Type: 3D Model

Mime Type: application/vnd.ms-package.3dmanufacturing-3dmodel+xml

Format: Binary

Description

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 that are compressed with the 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

If your 3MF file contains textures, these will be ignored. If a material contains color information this will be translated where possible.

Supported Features

  • Mesh geometry
  • Face and vertex colors

Unsupported Features

  • Textures

Extension: OFF

Full Name: Object File Format

Type: 3D Model

Mime Type: text/plain

Format: Text

Description

The OFF file format is a simple text-based format capable of storing 2D and 3D geometry and was originally developed for the Geomview application. There is also an extension to the OFF format used by the Stella4D application to enable storage of four-dimensional data.

The format can contain common vector information such as vertices, faces, shape, edge information and also has support for including color information. As the format is text based the files can become rather large with no built-in compression options available.

OFF Notes

OFF files support per face color information. If your uploaded model contains color information our tool will attempt to save this in the OFF file at the end of the conversion process.

Supported Features

  • Mesh geometry
  • Face colors
