3MF 3D Manufacturing File

An open-source XML file format developed by the 3MF Consortium, a collaboration of companies and organizations in the 3D printing industry. It was designed to overcome the limitations of older formats, such as STL, which only store geometric data, by providing a more comprehensive and extensible framework for additive manufacturing workflows.

Main Advantages Over STL

Unlike STL, 3MF can store additional information, making it a more advanced and versatile choice for additive manufacturing:

  • Color Support:

    Defines the color of individual triangles, enabling more realistic and visually detailed prints.
  • Transparency:

    Specifies opacity levels for triangles or vertices, allowing for the creation of transparent or translucent objects.
  • Textures:

    Supports texture mapping by associating 2D images with 3D models, enhancing realism in prints.
  • Metadata:

    Allows embedding custom data such as author, title, description, and license, facilitating better file management and sharing.

3MF File Conversion

Our products, Autoconverter and Automesher Application, are fully compatible with the 3MF file format. They utilize the official lib3mf library to enable seamless import and export of 3MF files. A significant limitation of the 3MF format is its lack of support for group hierarchies. When converting a 3D model containing nested subgroups - often used for organizational purposes - these structural relationships are not preserved in the 3MF file. Despite this, 3MF remains a powerful and modern format for 3D printing, offering a rich set of features that go beyond traditional STL files.


JSON CityJSON File

A modern, JSON based (JavaScript Object Notation) file format designed for storing 3D city models. It efficiently represents buildings, roads, bridges, and other urban features with support for textures, semantics, and metadata.

Key Features of CityJSON

  • JSON-Based:

    Lightweight, human-readable, and easy to parse (no complex XML like CityGML).
  • Semantic Richness:

    Preserves object attributes (e.g., building heights, roof types, road classifications).
  • LOD Support:

    Stores multiple Levels of Detail (LOD1 - LOD4) for flexible use cases.
  • Web-Ready:

    Works seamlessly with JavaScript, APIs, and 3D web viewers (like Cesium or Three.js).
  • Open Standard:

    Developed and maintained by the 3D Geoinformation Group (Delft University).
