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.

It is great for any manual calculation. You can lay it out as you would on paper, but the math is calculated instantly, similar to how it is in excel. It is superior to either method for most engineering calculations. Being able to copy-and-paste is very helpful for considering multiple scenarios. In some situations where you need to do the same calculation on an array of numbers, Excel is still faster.

Pros

Autodesk

  • 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.

  • Conversion of measurement units (Imperial and Metric)
  • Easy to use for writing detailed engineering worksheets
  • Formulas can be written in the expanded form which facilitates verification
  • Spell Checker feature is life saver.

Cons

Autodesk

  • 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.

  • Some of the math and text formatting aspects are a little cumbersome.
  • Converting from older Matchcad versions to the newer Mathcad Prime platform could be made easier. It should be a direct import function.

    Higher-order math, despite symbolics, become tedious and variable nomenclature isn't as forgiving as other programs. Due to it's sheet-like nature, the greater the complexity the more bothersome the screen usage becomes. But it's a trade-off between a sketchpad-like interface or lines and lines of code. Pick your poison but MathCad was our choice.

    Alternatives Considered

    Autodesk

    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.

    MathCAD is easier to learn and faster to start with. It has more user-friendly interface and conventional style toolbox and GUI. It is really good for the beginners and those who are afraid of complex math.

    • Speeds up calculations (especially when corrections need to be made near the beginning).
    • Ability to re-use old calculations as a template can save significant time.
    • You can use consistent formatting for all calculations, allowing for more organized, clear calculations.
