3D File Format Knowledge

Common 3D Formats

OBJ is widely supported and stores geometry data, while FBX preserves animations and materials. STL is popular for 3D printing but only stores mesh geometry without textures or colors.

Game Development

GLTF (GL Transmission Format) is considered the "JPEG of 3D" and optimized for web applications. It supports animations, materials, and textures while maintaining smaller file sizes.

CAD Formats

STEP and IGES are industry standards for CAD data exchange between different software. They preserve precise geometry needed for manufacturing, while formats like OBJ approximate surfaces with triangles.

3D Printing

STL is the most common format for 3D printing, but newer formats like 3MF include additional data such as colors, materials, and print settings in a single compressed file.

Fun Facts About 3D File Formats

  • •The OBJ format was developed by Wavefront Technologies in the 1980s and remains one of the most widely supported 3D formats despite its age.
  • •STL was created for stereolithography, the first commercial 3D printing technology, by 3D Systems in 1987.
  • •FBX (FilmBox) was originally developed by Kaydara for motion capture, before being acquired by Autodesk in 2006.
  • •GLTF was developed by the Khronos Group, the same organization behind OpenGL and Vulkan graphics APIs.

Did You Know?

Converting between 3D formats isn't always lossless. Some information might be lost when converting:

  • Animation data might not transfer between certain formats
  • Material properties can be simplified or lost entirely
  • High-precision CAD geometry can be approximated when converting to mesh-based formats
  • Some formats support scene hierarchies while others flatten everything
"Choose your 3D file format based on your workflow's end goal, not just what's convenient at the moment."

Why Convert Between 3D Formats?

Converting between 3D file formats allows you to:

  • Import models into software that only supports specific formats
  • Optimize file sizes for web or mobile applications
  • Prepare models for 3D printing or manufacturing
  • Archive work in industry-standard formats for long-term preservation
  • Share models with clients or collaborators using compatible formats
