How to Convert 3D Models into STL Files Using Revit
Installing the STL Exporter Plugin
- Download the Plugin
- Visit the STL exporter project page on SourceForge.
- Click on the folder for the version of Revit you are using and download the plugin.
- Install the Plugin
- Follow the installation instructions provided on the download page to install the plugin.
- Restart Revit
- Restart Revit to complete the installation process. An Add-ins tab should now appear on the menu bar.
Exporting to STL
- Accessing the STL Exporter
- Click on the Add-ins tab in Revit.
- Click on External Tools. A pull-down menu should appear.
- Select STL Export.
- Saving the STL File
- In the STL Export dialog, save the file as binary. The Categories should all be grey and checked by default.
- Click Save.
Troubleshooting
- Handling Export Issues
- If the STL export does not work or creates strange surfaces, load your file into a new project.
- Repeat the above steps to export the model again.
Additional Tips and Considerations
- Scale and Units
- Ensure your model is correctly scaled before exporting. The units in Revit should match the units your 3D printer uses to avoid scaling issues.
- Wall Thickness
- Verify that your model has appropriate wall thickness. Thin walls may not print correctly or may be too fragile. Check your 3D printer’s specifications for minimum wall thickness requirements.
- Model Orientation
- Consider the orientation of your model in the 3D printer. Proper orientation can reduce the amount of support material needed and improve the surface finish.
- File Size and Complexity
- STL files can become very large with high resolution. Ensure your computer can handle the file size and that your 3D printer’s software can process it. Simplify the model where possible to reduce file size without compromising print quality.
- Manifold Geometry
- Ensure your model is manifold (watertight). Every edge should be connected to exactly two faces. Non-manifold geometry can cause errors during 3D printing.
- Software Updates
- Keep your Revit software and 3D printer’s firmware updated. Updates often include bug fixes and new features that can improve the export process and print quality.
- Test Prints
- Before committing to a full-scale print, consider doing a small test print. This can help identify any potential issues and save material and time.
By following these steps and tips, you can ensure a successful conversion of 3D models into STL files suitable for 3D printing, resulting in high-quality prints and efficient use of resources.
