MeshMixer is one of the free 3D software<\/a> programs provided by Autodesk, which offers several interesting features to help users in not just modeling but also in 3D printing processes. Available on Windows and Mac OS, version 3.5 of MeshMixer relies on surface modeling to design any type of part from another model, on a triangular mesh. You can thus combine several shapes together, modify them according to your needs, analyze them before printing and export them in the right format. This free software is relatively simple to use and is intended for individuals, students and professionals who are new to modeling.<\/p>\n

In the 3D printing market, modeling<\/a> is the first step towards the design of a part. In fact, it is a key step in reducing the possibility of part failure, allowing for optimization of the quantity of material used, orientation of the part, and much more. Today, various modeling and CAD software<\/a> packages are available for all levels, and MeshMixer stands out for its ability to model a part from an existing model. In this sense, the software is a little different from a more traditional solution where you can start from scratch. But how exactly does MeshMixer work, and what are its features?<\/p>\n

MeshMixer has multiple functions.<\/p><\/div>\n

The Features of the 3D Software<\/h3>\n

As already mentioned, this software allows you to edit 3D models. To do this, simply import the file into MeshMixer, which supports a wide range of formats: STL, OBJ, PLY and AMF. Once the model has been imported, MeshMixer lets you modify, resize, measure or repair it. To do this, MeshMixer uses triangular meshes composed of three elements: vertices, edges and faces (or triangles). Vertices correspond to points in 3D space; edges connect two vertices and faces correspond to the association of three vertices.<\/p>

The software takes its name from its first feature, MeshMix. This is one of MeshMixer’s key features: it allows you to add different types of mesh using a classic Drag&Drop tool. In concrete terms, you can superimpose an arm or a foot on a previously imported object. The second feature is the Sculpture tool, which allows users to modify and personalize their models using different brushes. For example, it is possible to move vertices to enlarge the part, deform it, etc. Two types of tools are available: volume tools (3D spheres) and surface tools (2D disks).<\/p>\n

MeshMixer and 3D printing<\/h3>\n

The reason we’re so interested in this free 3D software is that it offers some interesting features for 3D printing. It offers editing tools for repairing your model, for example: use it to patch holes in a mesh, hollow out your model to use as little material as possible, or make it solid to guarantee a good print. MeshMixer also offers analysis functions to identify possible printing problems. It can check part thickness, orientation, strength and so on. It is also capable of generating optimal print supports.<\/p>\n

Finally, the software makes the printing process as easy as possible by allowing the user to choose the 3D printer or compatible material. The model can be viewed directly on the printer plates, clearly showing how the part will be positioned and printed. Several export formats are available such as .stl or obj.<\/p>\n
