MeshMixer 3.5

If you ever need to clean up a 3D scan, create a 3D model, or just do some 3D printing, there's a software program that will help you accomplish all these tasks.
The program is called MeshMixer, and it provides you with all the necessary tools for designing and printing 3D objects.

The installation process goes smoothly and can be done by even the most novice computer user. It has a decent-looking interface - not the most innovative one, but one that has big and visible action buttons, among some basic customization options. Still, the grey color theme gives the impression of an outdated interface.

MeshMixer offers its users a wide variety of tools and features. The most important ones are an option to realize 3D Sculpting and Surface Stamping, create branching structures for 3D printing or do 3D measurements.

Moreover, some advanced selection tools are available, such as surface-lasso and a brusher. Once selected, the mesh region can be replaced and the bulge levels can be refined, smoothened, and scaled.

Also, it supports Robust Convert-to-Solid and has an Automatic Print Bed Orientation Optimization, as well as an Automatic Alignment of Surfaces.

To conclude, MeshMixer is a good solution for realizing 3D projects, one that it's equipped with smart editing tools and, above all, it's free. Do keep in mind that you need to have a powerful high-end computer because it consumes a lot of system memory.
