Latest nightly version of Slicer has a dedicated file export feature. You have the option of saving as merged STL (all segments merged into a single mesh) or OBJ (single file, segments are different objects). See details here:

> We often received questions about how to export segmentation to STL file for 3D printing. We’ve added a simplified, dedicated tool to make this step easier. 1-minute demo video: [[Export Slicer image segmentation to STL or OBJ file] ](https://www.youtube.com/watch?v=WfuYPVYA5cA) Main features: Export STL file: each segment as a separate file or all segments merged into a single mesh Export OBJ file: all segments are saved in one file, segment colors and opacities are preserved Export all or visible segments only Coordinate sy…
