U3D Universal 3D File

An open standard for 3D data exchange, originally developed by the 3D Industry Forum to enable universal 3D visualization across platforms. As a compressed, binary file format, U3D efficiently stores three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates.

Key Features of U3D

  • Open Standard:

    Royalty-free format maintained by ECMA International (Standard ECMA-363).

  • PDF Integration:

    U3D enables the generation of PDF documents that contain interactive 3D data (ISO 32000). This means that you can view, rotate, zoom, and manipulate 3D models within a PDF document.

  • Compact Size:

    Optimized compression for web and document embedding.

  • Cross-Platform:

    Viewable across major operating systems without proprietary software.

U3D File Conversion

Our Autoconverter and Automesher Application utilize Intel's powerful open-source IFX conversion library to deliver robust U3D file conversion capabilities. This technology enables seamless two-way conversion between the U3D format and various industry-standard 3D formats including STL, OBJ, SKP, DAE, STEP, IGES, DWG, 3DS, FBX and X3D. The solution provides reliable transformation of 3D data while maintaining optimal file structure and visual fidelity throughout the conversion process.

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.
