![]() Luckily, with any platform and for no money at all you can have access to the extremely powerful mesh-repair services at MakePrintable. For professionals in industry this is probably reasonable, but for smaller businesses and hobbyists it’s pretty steep. Netfabb is free for students, but for the rest of us it costs $30, per month. ![]() If you have a Windows machine, you can try using the professional software Netfabb to repair this model. Alas, although MeshLab can identify these problems, it’s not able to actually fix them usual MeshLab repair menu options such as “Remove Faces from Nonmanifold Edges” and “Remove T-Vertices by Edge Flip” are unsuccessful here. When we added those new triangles, we created some bad geometry where the pairs of coincident faces meet. The problem lies with where the new faces intersect. However, when we try to open our broken file in MeshLab we get this error:Īfter opening the file and looking through some of the Cleaning & Repairing filters, we see that there are some non-manifold faces: It’s more complicated than Meshmixer, but can often take care of bad geometry like reversed normals and non-manifold faces. Although Meshmixer knows something is wrong here, its Inspector cannot repair it:Īnother great mesh-manipulation tool is MeshLab for a primer on making simple mesh fixes with MeshLab, check out our previous article Tutorial Tuesday 5: Quick Fixes With MeshLab. But, in this case, when we open our broken file in Meshmixer to see what’s going wrong, the faces don’t load in. Meshmixer is a great first tool for modifying 3D meshes for an in-depth example see our previous article Tutorial Tuesday 50: Using Meshmixer to Make 3D Models Thick Enough to 3D Print. ![]() Nice! But when we try to upload to Shapeways, we get this error message: The screenshot below shows what it looked like when I did this in TopMod I added the closed triangle faces, and everything seems fine: We’re going to turn this into a tealight ring and add some solid faces to the wireframe to create a partially-enclosed look. So that we can follow exactly what’s going wrong, we’ll create a bad mesh by modifying an existing 3D model, my Deltoidal Hexecontahedron Catalan Bracelet:
