A typical STL file repair workflow contains the following steps:
- Auto-repair. The STL repair software’s wizard will attempt to fix all major errors, including holes, separate shells, and intersections.
- Separating shells. A mesh consists of collections of connected triangles. It can contain multiple continuous surfaces that ideally are joined together while obsolete ones need removal.
- Closing holes, bridging gaps. Some comprehensive STL repair programs allow different ways of hole filling, such as planar, tangent, ruled, or freeform.
- Resolving overlaps and intersections. This typically requires recalculating entire portions of the mesh.
- Filtering out double faces, double vertices, inverted normals, and sharp, narrow triangles.
- Stitching open edges and remaining holes.
- Manual repair by deleting and creating triangles.
- Remeshing to optimize triangle count.
- Exporting to the chosen mesh format.

How Do I Fix an STL File That Needs Repair?
Now that we’ve seen some things that can go wrong with an STL file, it’s time for some good news. You can repair all these errors and print the STL file successfully.
What is STL repair?
Repairing STL files in 3D Printing is a valuable skill to learn when you come across files or designs that have errors. These are usually holes or gaps in the model itself, intersecting edges, or something called non-manifold edges.
What Are STL Errors in 3D Printing?
STL file errors in 3D Printing occur due to faults in the model or issues stemming from poor exportation of the CAD model.
How Do You Simplify & Reduce an STL File Size?
To simplify and reduce an STL file, all you need to do is to recalculate and optimize the mesh. For smaller file size, you’ll need a smaller number of triangles or polygons in the mesh.
What is STL file?
It’s the file format you convert your 3D objects into after modeling them in the CAD software. You can then send the STL file to a slicer to prepare it for Printing.
What is STL in 3D modeling?
STL, which stands for Standard Tessellation Language or Stereolithography, is a file format used in describing the surface geometry of a 3D object . It is important to note that it doesn’t contain any information about the model’s color, texture, or other attributes.

How to repair a hole in Netfabb?
When attempting to bridge gaps, Netfabb will rather fill the open holes which require further manual repairs. Tap the Select Surfaces icon on the main toolbar and select the entire hole, then hit Delete. Alternatively, use the Brush Selection tool and use Ctrl + Scrollwheel and the Plus/Minus buttons to alter brush size and selection. With the triangles selected, choose the Remove Selected Triangles icon and manually add missing triangles as well as a few bridging triangles with the Add Triangles button. The Repair → Close all Holes operation will complete the mesh repair task. Finally, we can opt to refine the mesh using the Mesh Edit → Remesh command which recomputes the model based on a Target Edge Length parameter. Check the Maintain Edge option to optimize model integrity around sharp edges.
How to delete triangles in Meshlab?
Hold the Alt key to leave backfaces out of the selection, use Shift + Ctrl + D to deselect. For selecting individual triangles, click the Z-Painting tool on the toolbar and select the red brush icon. Left click to select triangles, right click to erase the selection and hit delete to remove triangles. Because Mesh lab does not implement any triangle creation functions, we reside to the surface generation method under Filters → Remeshing, Simplification and Construction → Surface Reconstruction: VCG. With a low enough setting for Voxel Side and high enough value for Geodesic Weighting and Volume Laplacian Iterations, it will result in a smooth manifold mesh. This method is usually recommended over Filters → Remeshing, Simplification and Construction → Screened Poisson Surface Reconstruction. Another alternative method is to generate an Alpha Complex then generate an Alpha Shape which sometimes works with the right values. For remesh operations, Meshlab offers a voxeliser under Filters → Remeshing, Simplification and Construction → Uniform Mesh Resampling which results in a manifold mesh and offers an offset parameter useful for creating hollow parts.
How to fill a hole in Blender?
The simplest way to fill a hole in Blender is to first select the boundary loop with Select → Select Boundary Loop or select all non-manifold edges with Select → Select All by Trait → Non Manifold (Shift + Ctrl + Alt + M) and then hit Mesh → Faces → Make Edge/Face (F) or Mesh → Faces → Fill (Alt + F) for an improved fill. Individual triangles can be created by right-clicking an edge or vertex, Shift + right-clicking the second one and pressing F. It is helpful during editing to switch between Vertex Select, Face Select, or Edge Select modes that are indicated by three icons at the bottom toolbar. Selecting a particular area can be done with Select → Circle Select (C) which works similar to brush selection. Change the brush size with the mouse wheel or the numerical plus/minus buttons, deselect holding the Shift key. Mesh → Faces → Beautify Faces (Shift + Alt + F) sometimes works to improve mesh quality in the selected area. Individual boundary loops can be selected using Alt + Right click. With two open boundary loops selected, choose Mesh → Edges → Bridge Edge Loops and the two areas will be smoothly connected.
How to repair mesh in Meshlab?
For example, Filters → Cleaning and repairing → Select Self Intersecting Faces → Apply will select all intersecting triangles which can then be removed by pressing Delete. Filters → Cleaning and repairing → Remove Duplicated Faces and Remove Duplicated Vertex are always useful actions to perform. The next step is healing up holes using Filters → Remeshing, Simplification and Construction → Close Holes. The Compute Geometric Measures operation under Filters → Quality Measure and Computations will indicate when a mesh is not watertight. If not, detect the involved areas with Render → Show Non Manif Edges and Show Non Manif Vertices.
What to do if Boolean operation fails?
In that case, turn the Search Depth parameter up and lower the Target Edge Scale to increase the chance of success. Checking Use Intersection Curves also improves quality. If all else fails, moving one of the shells by a few hundredths of a millimeter in the Edit → Transform section will do the trick.
What is STL file?
STL file is the format that almost every slicer accepts. These files elaborate on the final product that one wants to realize. Hence, these must be prepared with the utmost care. For preparing these STL files, designers usually use surfacing methods for creating 3D models.
What is auto repair tool?

Can you use a manual interface to fix a hole?
It does try to fix some of the major challenges as well. However, you may have to use a manual interface for a few major issues. Some programs may have different methods for closing holes or bridging gaps. To eliminate the obsolete parts, one can even employ the separating shells feature.
How long does it take to fix a CAD file?
The repair service has a timeout of 4 minutes. That means if your file is not fixable in 4 minutes it cancels the operation to free up processing capacity for others. Analysis of our data has shown that almost all (serious) files are fixed within 4 minutes. In case of a timeout the most likely cause is that your model is far from a closed shell and the better approach would be to manually fix it in a CAD package.
