There are millions of 3D files, and not all of them have been 3D printed. There is a big chance that individual files were developed for screen viewing and could have printability issues. We developed a 3D viewer and analyzer to help you identify printability issues.
This will indicate whether the model has any issues or not.
the number of non-manifold edges in the model (highlighted in red inside the editor).
the number of boundary edges in the model (highlighted in magenta inside the editor).
the dimensions of the 3D model in centimeters as width, height and depth.
the number of triangles, number of vertices and the volume of the model.
Here’s a model that we can see has boundary edges. You will notice that it has 185 boundary edges. Zero non-manifolds and is yellowish which indicates that it is not printable.
