Likelihood to Recommend Autodesk MeshMixer is best for repairing STL files and basic modifications toward 3D printing. It is excellent for hollowing out models and adding escape holes for SLA printing or lost-wax casting. Its CSG (Boolean) functions to combine different meshes are good too and seldom cause the program to crash. There is even an integrated algorithm to optimize the layout of multiple files on a print bed in case of small-batch production. Autodesk MeshMixer's sculpting tools are there yet limited and there are a few better alternatives. Best of all, it is completely free.
Read full review Pros Auto-repair function works fast, and if it does not completely cover all problem areas, manual fixes will work 99.5% of the time. Remeshing algorithm is fairly slow but does a wonderful job in creating meshes with homogeneous or adaptive triangulation. It contains a comprehensive set of tools to optimize and prepare STL files for 3D printing, such as hollowing and support generation. Read full review Cons The remeshing tool needs to be faster, as in some cases it takes up to a day of waiting time. The sculpting tools need the addition of a proper brush for creating sharp creases and ridges. The standard shape library is rather limited. It would be nice to have this connected to online repositories such as Thingiverse, MyMiniFactory, or Cults3D. Read full review Alternatives Considered Using
Blender for STL file preparation is like swatting a mosquito with a wrecking ball, plus its boolean functionalities can be glitchy. ZBrushCoreMini proved too limiting as a sculpting tool, but so did Autodesk MeshMixer, so I am sticking to Sculptris. Materialise Magics and Netfabb are somewhat better at STL file repair and offer more advanced functionalities. But Magics does not remesh as well and Autodesk MeshMixer is far more compact and faster than Netfabb, so remains my weapon of choice.
