Visualizing and fixing

The STL format describes triangles in Euclidean space. The triangles should touch to form the surface of a 3D object. Some tools, especially Google Sketchup, generate STL files that have extra triangles inside or outside the object, which can lead to complaints by Slic3r and other tools that the object is not manifold.

netfabb Cloud is an online tool that can fix your STL files. You can upload your STL file and then download a fixed STL file, which you can then slice.

netfabb Cloud can be a bad choice if your STL file is particularly large, both because it has a hard time fixing large files and because it will take a long time to upload. Use the free desktop version, netfabb Studio Basic, instead. You must fix the object and then right-click the fixed version and export as STL.

netfabb Studio Basic will render your STL, but it is hard to navigate. MeshLab is a good tool for viewing and inspecting 3D models and making minor adjustments such as rotations.
