.las and .laz (compressed LAS) files, the standard formats produced by LiDAR scanners, drones, and surveying equipment.
Uploading
LAS and LAZ files upload like any other model — drag them onto the upload area or browse for them. There’s no extra configuration step; the point cloud is loaded and processed directly.A point cloud has no surface of its own. Repairing a LiDAR scan reconstructs a solid, watertight surface that wraps the points, which is what makes it printable.
Repairing
Because the input is points rather than a mesh, repair focuses on building a clean surface from them:- The points are turned into a continuous, watertight surface.
- Floating stray points and noise are cleaned up in the process.
- Wall thickness and other advanced settings apply to the reconstructed surface, just like a regular model.
Scale matters
LiDAR scans often come in real-world units and can be very large (a building, a landscape). Set a target size with Scale settings so the result fits your printer’s build volume.Tips
- Denser scans reconstruct into more detailed surfaces; very sparse clouds may produce a coarse result.
- If the reconstruction looks noisy, a little smoothing cleans up scanning artifacts.
- Use Object Info to check the model’s real-world dimensions before scaling.
