Convert DAE to 3MF Online (Free & Secure)
iLove3DM converts DAE files to 3MF online and free: .dae in, .3mf out. DAE is verbose XML following the Khronos COLLADA schema, while 3MF is a zip package of XML model data and thumbnails; the converter bridges the two using GLB as an intermediate scene.

iLove3DM converts DAE files to 3MF online and free: .dae in, .3mf out. DAE is verbose XML following the Khronos COLLADA schema, while 3MF is a zip package of XML model data and thumbnails; the converter bridges the two using GLB as an intermediate scene.
Modelling and animation formats carry far more data than a printer needs, so the converter keeps the surface and drops everything else. DAE (.dae) is verbose XML following the Khronos COLLADA schema. It holds polygon meshes with scene graph, cameras and lights and is most often opened in SketchUp, Blender, and Google Earth. 3MF (.3mf) is a zip package of XML model data and thumbnails, holding indexed triangle meshes with build items and component assemblies, and is typically used in Bambu Studio, PrusaSlicer, and Cura.
Because DAE uses COLLADA effects (Blinn, Phong, Lambert) with image references while 3MF uses base materials, colour groups and multi-material assignments, the converter reads your scene, applies the mapping described below and writes a clean .3mf file. Everything runs in your browser or an isolated, auto-purged instance, so models stay private.
.daeAbout DAE (Collada)
ISO-standard XML schema for exchanging digital assets between graphics software applications.
- Structure: verbose XML following the Khronos COLLADA schema
- Materials: COLLADA effects (Blinn, Phong, Lambert) with image references
- Units: a unit scale declared in the asset header (often meters or inches)
- Axis: either Y-up or Z-up, as declared in the file
- Opens in: SketchUp, Blender, Google Earth, Gazebo or Rviz
.3mfTarget format: 3MF (3D Manufacturing Format)
Modern successor to STL for additive manufacturing. Contains color, materials, multi-part assemblies, and slice data.
- Structure: a zip package of XML model data and thumbnails
- Materials: base materials, colour groups and multi-material assignments
- Units: millimeters (declared in the model file)
- Axis: Z-up, matching the print bed
- Opens in: Bambu Studio, PrusaSlicer, Cura or Windows 3D Builder
What happens to your data in DAE → 3MF conversion
Conversion route: DAE → GLB → 3MF (parsed into a GLB scene, then exported as 3MF).
| Aspect | Result | Outcome |
|---|---|---|
| Geometry | Preserved | DAE stores polygon meshes with scene graph, cameras and lights; 3MF stores indexed triangle meshes with build items and component assemblies. Surfaces are retriangulated where needed and positions, normals and UV coordinates are carried across. |
| Materials | Preserved | DAE uses COLLADA effects (Blinn, Phong, Lambert) with image references and 3MF can represent the same information, so base colour and surface settings are preserved. |
| Textures | Preserved | In DAE, textures are referenced as external image files. 3MF can reference or embed textures too, so images and UV mapping stay linked. |
| Vertex colours | Preserved | Per-vertex colours in DAE are written to 3MF as vertex colour data. |
| Animation | Not supported | DAE provides skeletal animation, controllers and kinematics, but 3MF is a static format and animation is not exported. |
| Units & scale | Adapted | DAE uses a unit scale declared in the asset header (often meters or inches); 3MF uses millimeters (declared in the model file). Check the scale in your target application, and use the Scale tool if the model looks too big or too small. |
| Orientation | Adapted | DAE is either Y-up or Z-up, as declared in the file and 3MF is Z-up, matching the print bed. The converter writes a consistent orientation, but verify the up axis in your target software. |
Expect the 3MF file to be roughly 3.8x smaller than the DAE source, since 3MF is compact, because the XML is zipped.
Why convert DAE to 3MF?
Why leave DAE
People most often convert from DAE when they are retiring an XML-heavy archive into a compact format. Other common cases include opening a SketchUp or robotics export in a modern pipeline and making a legacy Collada asset viewable on the web. In DAE → 3MF specifically, preserved: geometry, materials, textures, and vertex colours; adapted: units & scale and orientation; not supported by 3MF: animation. Expect the 3MF file to be roughly 3.8x smaller than the DAE source, since 3MF is compact, because the XML is zipped.
Why choose 3MF
3MF is the right target when you are replacing STL with a smaller, richer print format. It also fits scenarios such as multi-colour and multi-material 3D printing and delivering a model with correct millimeter scale to a slicer. Modelling and animation formats carry far more data than a printer needs, so the converter keeps the surface and drops everything else.
Where the result opens
After conversion you can open the .3mf file in Bambu Studio, PrusaSlicer, Cura or Windows 3D Builder.
Step-by-Step Guide: DAE → 3MF
- 1
Upload your .dae file
Drag your DAE model onto the converter or click to browse. Textures are referenced as external image files; zip the model with its textures and companion files if you want them included.
- 2
Check your free quota
Free accounts can run a few conversions per day; signing in unlocks tracking of your remaining uses. No watermark is ever added.
- 3
Convert to 3MF
Press the Convert to 3MF button. The pipeline follows DAE → GLB → 3MF (parsed into a GLB scene, then exported as 3MF), which usually takes a few seconds for models under 100 MB.
- 4
Download the .3mf file
Your 3MF file downloads automatically. Open it in Bambu Studio and PrusaSlicer to confirm scale and orientation.
Tips for DAE → 3MF
- External texture paths break when files are moved (DAE source).
- Multi-material assignments rarely map to other formats (3MF target).
- Always verify real-world size: DAE is a unit scale declared in the asset header (often meters or inches), while 3MF is millimeters (declared in the model file).
- Since DAE is much heavier than 3MF, converting is also a good way to shrink your asset.
Frequently Asked Questions
How do I convert DAE to 3MF without losing quality?
Upload the .dae file and press convert; the route is DAE → GLB → 3MF (parsed into a GLB scene, then exported as 3MF). Geometry is carried over exactly; materials are preserved, and textures stay linked through UV coordinates.
Does DAE to 3MF conversion keep textures?
In DAE, textures are referenced as external image files. 3MF can reference or embed textures too, so images and UV mapping stay linked.
Why does my 3MF model look the wrong size or rotation?
DAE uses a unit scale declared in the asset header (often meters or inches); 3MF uses millimeters (declared in the model file). Check the scale in your target application, and use the Scale tool if the model looks too big or too small. DAE is either Y-up or Z-up, as declared in the file and 3MF is Z-up, matching the print bed. The converter writes a consistent orientation, but verify the up axis in your target software.
Will the 3MF file be bigger or smaller than my DAE file?
Expect the 3MF file to be roughly 3.8x smaller than the DAE source, since 3MF is compact, because the XML is zipped.
What software can open the converted 3MF file?
3MF files open in Bambu Studio, PrusaSlicer, Cura or Windows 3D Builder. If you need to go back, use the 3MF to DAE converter.
Is it safe to upload my DAE model?
Yes. Files are processed in your browser or on isolated instances and purged right after conversion. They are never used to train AI models, and no watermark is added.
