Informazioni sullo strumento
GLTF is the standard 3D format for the web, but 3D printing workflows require STL. This tool extracts all mesh geometry from GLTF scenes — including nodes and instanced meshes — and generates a unified STL file ready for slicing.

Domande frequenti
Does the converter handle GLTF files with external resources?
GLTF files reference external textures and binary buffers via URIs. For STL conversion only the geometry data is needed, so missing texture references will not prevent conversion. Ensure the .bin buffer file is available if your GLTF uses an external buffer.
Will animations in the GLTF be included in the STL?
No. STL is a static mesh format and does not support animations, skins, or morph targets. Only the default pose mesh geometry will be converted.
Do I need to upload external resource files with my GLTF?
For STL conversion, only geometry data is needed — texture files are not required. However, if your GLTF references an external .bin buffer for mesh data, make sure the buffer file is in the same directory as the GLTF file.
How are instanced meshes in GLTF handled?
GLTF supports mesh instancing via transform matrices. During conversion, each instance is expanded into independent geometry, and all instances are included in the output STL file.
Will multiple models in a GLTF scene be merged into one STL?
Yes, all visible mesh nodes in the scene graph are merged into a single STL file. If you need separate models, edit the GLTF to keep only the target meshes before converting.
How can I verify if the STL mesh is watertight?
Import the STL into your slicer — most slicers automatically detect non-manifold edges and open boundaries. You can also use online mesh validation tools to check printability before printing.
