GLTF to 3MF Conversion

Step-by-step instructions to help you transform GLTF into 3MF with ease:

  1. Install Autoconverter

    Download and install Autoconverter on your system. Launch the software to convert GLTF files to 3MF format.

  2. Import GLTF File

    Click Open... to load your GLTF (.gltf, .glb) file, or drag and drop it into the application window.

  3. Export to 3MF Format

    Use Save As... to export your file to the 3MF mesh file format (.3mf).

GLB GLTF and GLB 3D File Format

The GLTF (GL Transmission Format) and GLB file types are modern open standards developed by the Khronos Group for efficient storage, transmission, and rendering of 3D models. Designed for the web, gaming, VR/AR, and real-time applications, these formats enable compact, high-performance 3D asset workflows across platforms.

Key Features of GLTF and GLB Files

  • GLTF Versions:
    • GLTF 1.0: Supports basic geometry, textures, simple materials, and skeletal animations with joint hierarchies.
    • GLTF 2.0: Adds advanced features like PBR (Physically Based Rendering) materials, Draco compression, morph targets, skinning, and enhanced animation capabilities.
  • ASCII vs Binary: GLTF files are human-readable (JSON format), while GLB files combine 3D data, textures, and materials into a compact, binary format for faster loading and easier distribution.
  • Embedded Textures: Both GLTF and GLB can embed textures directly, creating self-contained 3D assets ideal for web and mobile applications.

Convert GLTF and GLB Files

With Autoconverter and Automesher Application, you can easily import, export, and convert GLTF and GLB files to formats like OBJ, FBX, STL, and more. Our software supports Draco compression, enabling significantly smaller file sizes while preserving the quality and performance of your 3D assets.

3MF 3MF (3D Manufacturing Format) File

The 3MF (3D Manufacturing Format) is an open-source XML-based file format developed by the 3MF Consortium - an industry group composed of leading companies in the 3D printing sector. 3MF was specifically designed to address the limitations of older formats like STL, offering a richer, more extensible framework for modern additive manufacturing workflows. With 3MF, you can store not just the model geometry, but also color, textures, material properties, and metadata within a single file.

Key Advantages of 3MF Over STL

Unlike traditional STL files that store only basic 3D geometry, the 3MF format provides a wide range of enhanced capabilities:

  • Color Support: Enables full-color 3D printing by defining colors per triangle or per object, enhancing model realism.
  • Transparency and Opacity: Supports adjustable transparency for parts of the model, allowing the creation of translucent and transparent objects.
  • Texture Mapping: Associates 2D image textures with 3D surfaces, producing highly detailed and visually realistic prints.
  • Embedded Metadata: Includes detailed information such as author, copyright, licensing, description, and more—improving project management and file documentation.

3MF File Conversion and Workflow

Our Autoconverter and Automesher Application offer full support for importing, exporting, and converting 3MF files. Powered by the official lib3mf library, our software ensures high compatibility and reliable file processing across various 3D printing and CAD workflows.

Note: A current limitation of the 3MF format is its lack of support for nested group hierarchies. When converting complex 3D models with subgroup structures, the hierarchy will be flattened during export. Nevertheless, 3MF remains a highly advanced and preferred format for professional 3D printing, providing significant advantages over older standards like STL.
