MeshMixer is a 3D design and modeling tool for 3D printing or scanning, supported by Autodesk (acquired 2011). While not discontinued, the product will not receive updates and Autodesk states they intend to include all functionality in updates of Fusion 360.

Autodesk offers Tinkercad, a 3D modeling and design tool available free for educational purposes. Shapes are the building blocks of Tinkercad. Users can add pre-existing shapes, or import them. To adjust objects, users can rotate the workplane to adjust shapes or change views and input exact dimensions with the ruler. Custom shapes can also be created by combining elements.
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.
Tinkercad is such a great program and I would recommend the program to anyone who wants an introduction to a simple CAD program. I have another colleague that is now using it in her classroom due to my recommendation. I have had students start with me in Tinkercad and eventually work their way up in skill and purchase other Autodesk products because of the enjoyment and opportunity that Tinkercad provided.
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.
The Tinkercad provided projects were upgraded in some aspects but the text for the projects has not and can cause confusion.
Tinkedcad works best in Google Chrome on a windows machine but most of my students have Macs and even when using Chrome they run into issues that Windows users don’t
Tinkedcad is browser-based but, to have a program that would be tablet compatible would be invaluable. So far it has only really worked on a Surface Pro 3.
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.
Autodesk Tinkercad is by far the most user-friendly 3D modeling program I have used, especially for basic 3D modeling tasks. MeshLab and MeshMixer have similar functions but are far more complicated to navigate and difficult to use. These programs also tend to crash frequently, which has never been a problem with Tinkercad. The fact that you can use Tinkercad without downloading any software also makes it far more accessible, as you can log into your account and edit your models from any computer. I use 3ds Max for more complex 3D modeling, but for small tasks I always choose Tinkercad.
