OBJ Alias Wavefront Object File

A text-based file format, open standard for storing and exchanging 3D geometry data, widely used across 3D modeling, animation, and rendering software. Unlike binary formats, OBJ files store mesh data in human-readable text, making them highly compatible but less storage-efficient.

Main Benefits and Features

  • Named Group Objects:

    OBJ files can store multiple objects with different names in a single file, which can be useful for organizing complex 3D scenes.
  • Surface Materials:

    The OBJ file format supports surface materials with transparent colors and texture images, providing more realistic and detailed 3D models.
  • Geometry Primitives:

    OBJ files can store geometry primitives in the form of quads or triangles. However, during the OBJ file conversion using our converters, any quad primitives will be simplified into two triangles, as only triangular facets are supported.
  • OBJ File Size:

    Due to its textual format, OBJ files tend to have larger sizes compared to binary file formats like 3DS (3D Studio) or SKP (SketchUp). This means that OBJ files may take longer to load or transfer, and may require more storage space.

OBJ File Conversion

Autoconverter is the best OBJ file converter due to its high accuracy, fast processing speed, and wide 3D format support. It ensures lossless conversions while preserving model details, offering a user-friendly interface for seamless file conversion. If you need to handle OBJ files in AutoCAD, you can use our Automesher Application, which allows for seamless import and export of OBJ files directly in your CAD environment.


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.
