About This Tool

GLB is a common 3D format on the web, while 3MF is a modern 3D printing format that supports colors and textures. Mesh geometry, UV coordinates and base color textures carry over from GLB into the 3MF file, so major 3D printing slicers can print it in color.

Frequently Asked Questions

View all FAQs

Will the converted 3MF file retain the original model's colors and textures?

Yes, the tool packages the base color texture along with UV coordinates from the GLB into the 3MF file, supporting color printing and preview. However, other surface details such as bump maps and reflections will not be retained because 3MF is primarily focused on color and shape.

Can I preview the converted 3MF on Windows without extra software?

Yes. Windows has built-in preview support for 3MF, so you can double-click the file to see the model. Slicers such as Microsoft 3D Builder, PrusaSlicer, Cura, Chitubox, Fusion 360, and the Any3D 3MF viewer also open it for printing.

My GLB model has animations: will they be preserved in the conversion?

No. 3MF is a static model format. Only the original shape, materials, and textures are retained. Animations, bones, and other dynamic content will be discarded.

Is the converted 3MF file suitable for multi-color 3D printing?

If the model has a color texture, the converted 3MF file can be used for texture-mapped color printing. However, for multi-color printing that assigns different materials to different regions, we recommend using a dedicated slicer for setup.

My GLB contains multiple objects: will they become separate parts in the 3MF?

Yes. Each mesh is converted into its own object in the 3MF with its position and transform preserved, so the parts stay independent for slicing, coloring, or printing.

My GLB has no color texture: what will the converted 3MF look like?

Without a color texture, the 3MF contains the untextured geometry with the material's base color. You can still assign colors or paint the model in your slicer afterwards; color is optional in 3MF.

Up axis

Determines the 'up' axis of the exported model. Different 3D software uses different conventions. Selecting the wrong system may cause the model to lie on its side.
  • Y-up: Convention used by OpenGL, Three.js, and most Web 3D engines. Choose this for models from web or game engines.
  • Z-upRecommended: Convention used by Blender (default), 3ds Max, and some CAD software. Try this if the model appears sideways.
Z-up

Rotation X

Rotate the model around the X axis (degrees). Useful for correcting axis misalignment or print orientation.0°-180° – 180°

Rotation Y

Rotate the model around the Y axis (degrees). Useful for correcting axis misalignment or print orientation.0°-180° – 180°

Rotation Z

Rotate the model around the Z axis (degrees). Useful for correcting axis misalignment or print orientation.0°-180° – 180°

Rotation Application

Choose how rotation is written to the exported model. Baking into vertices rewrites all vertex coordinates so every export format (including geometry-only formats such as STL and STEP) applies it consistently; root node transform keeps the original vertex coordinates, which is friendlier to animated or skinned models, but formats that ignore node transforms (such as STEP) won't apply the rotation.
  • Bake into vertices: Rotation is written into all vertex coordinates and applies consistently to every export format; geometry data is rewritten.
  • Root node transformRecommended: Rotation is written as a root node transform while vertex coordinates stay unchanged; better for skinned or animated models, but formats that ignore node transforms (such as STEP) won't apply it.

Input format

Extension:
glb
Full Name:
GL Transmission Format Binary (glTF 2.0)
Type:
3D Model
Format:
GLB
Tools:
Three.js、Babylon.js、Blender
Open With:
3D Model Viewer、GLB Viewer
Description:
GLB is the binary glTF 2.0 format from Khronos Group, packing meshes, materials, textures, and animations into one file. It is the standard for Web 3D and AR/VR, used by Three.js, Babylon.js, model-viewer, and e-commerce previews for self-contained, reliable distribution. GLB supports PBR materials, skeletal animations, Draco and Meshopt compression, suitable for web, AR, and cross-software use. However, it loses CAD parametric history when tessellated from STEP or native CAD. For 3D printing, use STL or 3MF as slicers cannot import GLB.

Notes:

  • Some 3D printing slicers cannot directly import GLB files
  • Not suitable for CAD parametric editing

Supported Features:

  • Single self-contained binary file
  • PBR material support (base color, metallic, roughness, normal maps)
  • Skeletal animation, skinning, and morph targets
  • Draco mesh compression and KTX2 texture compression
  • Multi-mesh nodes and scene hierarchy

Description:
3MF is a modern 3D printing format from the 3MF Consortium, based on XML and packaged as a ZIP container. It preserves mesh data and supports per-part color, material, texture, and print properties. It is recommended for multi-color and multi-material printing. Major slicers (Bambu Studio, PrusaSlicer, OrcaSlicer) have native support. Compared to STL, 3MF carries richer information but is more complex. Some older slicers and printers may not recognize it. When converting from other formats, color and material mapping depend on source data. For simple single-color printing, STL remains sufficient. For multi-color, multi-material, or print parameter transfer, choose 3MF.

Notes:

  • Some older slicers and printers may not support 3MF
  • More complex than STL but carries richer information

Supported Features:

  • Per-part and per-vertex color support
  • Material and texture preservation
  • XML-based with ZIP compression
  • Native support in Bambu Studio, PrusaSlicer, OrcaSlicer
