------------------------------------------------------------3. Description------------------------------------------------------------This dataset accompanies the paper *Fabrication-aware structural form-finding for additive manufacturing: An equilibrium-based approach*and contains all relevant data for reproducing and understanding the workflow from computational form finding to physical fabrication.

Included files:1. Grasshopper Definition (.ghx) — The parametric model used for form finding.2. OBJ Files (.obj) — Generated and laser-scanned geometries for comparison.3. MP4 Files (.mp4) — Videos documenting the additive manufacturing / robotic printing process.

------------------------------------------------------------4. File Overview------------------------------------------------------------| File Type | Folder / File Name Example | Description ||------------|----------------------------|--------------|| .ghx | /scripts/form_finding_definition.ghx | Grasshopper file performing structural form finding. || .obj | /geometry/generated_form.obj /geometry/laser_scan.obj | Mesh geometries: computational vs. scanned. || .mp4 | /videos/printing_sequence_01.mp4 | Video documentation of the printing process. |

------------------------------------------------------------5. Software Requirements------------------------------------------------------------- Rhinoceros 7 or later- Grasshopper (pre-installed with Rhino)- Optional plug-ins: Karamba3D, Human- Any 3D viewer for .obj files (e.g., MeshLab, Rhino, Blender)- Standard media player for .mp4 files

------------------------------------------------------------6. Data Usage and Reproduction------------------------------------------------------------To reproduce the workflow:1. Open the .ghx file in Rhino + Grasshopper.2. Adjust parameters as needed (e.g., boundary conditions, loads, constraints).3. Export resulting geometries to .obj format.4. Compare exported .obj to the laser-scanned version using Rhino or CloudCompare.5. Review the .mp4 files for fabrication details and material behavior.
