How do I convert a DAE file to STL?

Drop the .dae into the converter above - the geometry parses locally in your browser and downloads as binary .stl in seconds. No account or software needed.

What is a DAE file exactly?

COLLADA (.dae) is an XML-based 3D interchange format from 2004 - the standard export of SketchUp and many older tools and marketplaces. It has largely been replaced by glTF/GLB, which is why so much legacy content needs converting out of it.

Can I print a SketchUp model this way?

Yes - export your SketchUp model as COLLADA (.dae), convert it here, and slice the STL. One caution: SketchUp geometry is often not 'watertight' (single-face walls with zero thickness), which printers cannot print - run the STL through a mesh repair tool if the slicer complains.

My DAE references texture images - is that a problem?

Not for this conversion. STL cannot store textures anyway, so missing texture files are ignored and the geometry converts normally.

Is my file uploaded to a server?

No - the XML parsing and STL writing run entirely in your browser. Your file never leaves your device.

Will the size be right in my slicer?

Coordinates are copied 1:1. COLLADA files declare their own unit (SketchUp typically exports meters or inches), while slicers read STL as millimeters - so verify the imported size and scale in the slicer if needed.

DAE and STL, explained

.dae

What is DAE?

COLLADA (.dae) is an XML-based interchange format that predates glTF. It can carry full scenes with materials, rigs, and animations, and remains common in SketchUp exports, older asset marketplaces, and legacy game pipelines.

As an XML format, .dae files are verbose and slow to parse, and tool support has been fading in favor of glTF/GLB and FBX. It survives on two ecosystems: SketchUp imports COLLADA natively (most other mesh formats need Pro or plugins), and Second Life accepts mesh uploads only as .dae - so files move both ways, legacy assets out and fresh conversions in.

.stl

What is STL?

STL is the oldest and most universal 3D printing format. It describes a model as a plain list of triangles - nothing else. No colors, no materials, no units, no object names. That simplicity is exactly why every slicer, CAD tool, and print service on earth accepts it.

An STL file stores each triangle as three corner points plus a facet normal, either as compact binary (the common case) or human-readable ASCII. Because the format carries no unit information, almost every tool assumes millimeters. When a file needs to work absolutely anywhere, STL is still the safe answer.

Developed by: 3D Systems (1987)
Structure: Binary or ASCII list of raw triangles
Used by: Every slicer, CAD package, mesh-repair tool, and 3D-printing marketplace

What survives the dae to stl conversion

Format conversion is honest work: some data has nowhere to go in the target format. Here is exactly what carries over.

Mesh geometry

All meshes in the COLLADA scene are carried over exactly, with scene transforms applied.

Scene assembly

COLLADA node hierarchies are flattened with transforms baked in - the STL matches the assembled scene.

Units

COLLADA declares a unit (often meters); slicers read STL as millimeters. Coordinates copy 1:1 - check the size on import and scale if needed.

Materials & textures

STL is geometry-only. COLLADA materials and any external texture files are not carried (and are not needed for printing).

Rigs & animations

COLLADA can store skeletal animation; STL cannot. The mesh exports in rest pose.

When should you convert DAE to STL?

Convert to STL to print geometry trapped in legacy .dae files - SketchUp exports, old asset-store models, Second Life content. Slicers never learned COLLADA; STL works everywhere.

If the asset is staying digital, convert the .dae to GLB instead of STL - GLB keeps materials and animations and is what modern viewers and engines expect. STL only makes sense on the way to a printer.

Only have a picture, not a 3D file? The image to STL converter turns photos and logos into printable models.

And if what you actually need is a new model rather than a new file format: 3D AI Studio's main tool can generate 3D models from photos with AI - with exports to every format on this page.
