Documentation / Node reference / geo nodes
Writes the input triangle meshes to a binary STL file, the format every slicer reads.
Files
STL is a bare triangle soup: no units, no colour, no object names, which is why a slicer has to guess whether the numbers are millimetres or inches. Use it for the widest compatibility, and geo/ThreeMFExporter when any of that matters. The file carries no transform, so every object's world placement is baked into the triangles written. Non-triangle geometries are skipped, and an empty input simply writes nothing.
| Name | Type | What it does |
|---|---|---|
| mergeInputObjects | Bool | Write every object on the input into the single triangle soup an STL holds. Off writes only the first one, which is faster but silently drops the rest. |
| fileNameMode | UInt8 NODE_NAME · NODE_PATH · CUSTOM_NAME | How the file is named: after this node, after the node's full path in the scene (still unique when exporters in different subnets share a name), or after the name param typed below. |
| name | String | File name to write, without the .stl extension. |
| download | Button | Cook the node and write the file. |
Scenes you can open in the editor that teach this node.
A two-part nameplate written to STL three ways: everything merged into the one mesh the format holds, only the first object, and the same model with no printer preparation so you can see what a slicer makes of a Y-up model with no units.
