⚡ AI Summary & Quick Answer
3MF to DAE conversion on iLove3DM takes one upload and no account. Your 3MF model, built from indexed triangle meshes with build items and component assemblies, is rewritten as DAE with its materials intact.
Moving a print-ready mesh into a general modelling format lets you re-sculpt, retexture or rig a part that started life as a printable file. 3MF (.3mf) is a zip package of XML model data and thumbnails. It holds indexed triangle meshes with build items and component assemblies and is most often opened in Bambu Studio, PrusaSlicer, and Cura. DAE (.dae) is verbose XML following the Khronos COLLADA schema, holding polygon meshes with scene graph, cameras and lights, and is typically used in SketchUp, Blender, and Google Earth.
The converter parses the 3MF scene graph, normalises meshes and materials, and re-exports them as DAE. Units change from millimeters (declared in the model file) to a unit scale declared in the asset header (often meters or inches). Everything runs in your browser or an isolated, auto-purged instance, so models stay private.
.3mfAbout 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
.daeTarget format: 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
What happens to your data in 3MF → DAE conversion
Conversion route: 3MF → GLB → DAE (parsed into a GLB scene, then exported as DAE).
| Aspect | Result | Outcome |
|---|---|---|
| Geometry | Preserved | 3MF stores indexed triangle meshes with build items and component assemblies; DAE stores polygon meshes with scene graph, cameras and lights. Surfaces are retriangulated where needed and positions, normals and UV coordinates are carried across. |
| Materials | Preserved | 3MF uses base materials, colour groups and multi-material assignments and DAE can represent the same information, so base colour and surface settings are preserved. |
| Textures | Preserved | In 3MF, texture and colour support exists but is mainly used for print colouring. DAE can reference or embed textures too, so images and UV mapping stay linked. |
| Vertex colours | Preserved | Per-vertex colours in 3MF are written to DAE as vertex colour data. |
| Animation | Not applicable | 3MF is a static format, so the DAE result is a single static pose. |
| Units & scale | Adapted | 3MF uses millimeters (declared in the model file); DAE uses a unit scale declared in the asset header (often meters or inches). Check the scale in your target application, and use the Scale tool if the model looks too big or too small. |
| Orientation | Adapted | 3MF is Z-up, matching the print bed and DAE is either Y-up or Z-up, as declared in the file. The converter writes a consistent orientation, but verify the up axis in your target software. |
Expect the DAE file to be roughly 3.8x larger than the 3MF source, because DAE is large because of XML overhead.
Why convert 3MF to DAE?
Why leave 3MF
People most often convert from 3MF when they are extracting geometry from a multi-colour print file. Other common cases include previewing a sliced project or print model outside a slicer and repurposing a printable part in a render or web scene. In 3MF → DAE specifically, preserved: geometry, materials, textures, and vertex colours; adapted: units & scale and orientation. Expect the DAE file to be roughly 3.8x larger than the 3MF source, because DAE is large because of XML overhead.
Why choose DAE
DAE is the right target when you are importing into SketchUp, Google Earth or ROS simulations. It also fits scenarios such as supplying assets to engines that still expect Collada and archiving a scene with its hierarchy in an open XML standard. Moving a print-ready mesh into a general modelling format lets you re-sculpt, retexture or rig a part that started life as a printable file.
Where the result opens
After conversion you can open the .dae file in SketchUp, Blender, Google Earth, Gazebo or Rviz.
Step-by-Step Guide: 3MF → DAE
- 1
Upload your .3mf file
Drag your 3MF model onto the converter or click to browse. Texture and colour support exists but is mainly used for print colouring; no extra files are required.
- 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 DAE
Press the Convert to DAE button. The pipeline follows 3MF → GLB → DAE (parsed into a GLB scene, then exported as DAE), which usually takes a few seconds for models under 100 MB.
- 4
Download the .dae file
Your DAE file downloads automatically. Open it in SketchUp and Blender to confirm scale and orientation.
Tips for 3MF → DAE
- Slicer-specific metadata is not part of the standard geometry (3MF source).
- Z_UP files appear lying on their side in Y-up tools (DAE target).
- Always verify real-world size: 3MF is millimeters (declared in the model file), while DAE is a unit scale declared in the asset header (often meters or inches).
- DAE files grow quickly; compress or decimate the source with the Compress tool if size is a concern.
Frequently Asked Questions
How do I convert 3MF to DAE without losing quality?
Upload the .3mf file and press convert; the route is 3MF → GLB → DAE (parsed into a GLB scene, then exported as DAE). Geometry is carried over exactly; materials are preserved, and textures stay linked through UV coordinates.
Does 3MF to DAE conversion keep textures?
In 3MF, texture and colour support exists but is mainly used for print colouring. DAE can reference or embed textures too, so images and UV mapping stay linked.
Why does my DAE model look the wrong size or rotation?
3MF uses millimeters (declared in the model file); DAE uses a unit scale declared in the asset header (often meters or inches). Check the scale in your target application, and use the Scale tool if the model looks too big or too small. 3MF is Z-up, matching the print bed and DAE is either Y-up or Z-up, as declared in the file. The converter writes a consistent orientation, but verify the up axis in your target software.
Will the DAE file be bigger or smaller than my 3MF file?
Expect the DAE file to be roughly 3.8x larger than the 3MF source, because DAE is large because of XML overhead.
What software can open the converted DAE file?
DAE files open in SketchUp, Blender, Google Earth, Gazebo or Rviz. If you need to go back, use the DAE to 3MF converter.
Is it safe to upload my 3MF 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.
