What began as a daring invention has gone on to become one of the greatest technological advancements of this century. Blender is also an excellent free program, but I find Wings to be much simpler to use.3D Printing has come a very long way from its early inception in the early 80s. Since both programs are free you can try them and uninstall them if they do not fill your needs. One of the features of Wings which has been quite valuable is the smoothing app which reduces the sharp division lines on some models.

Using these two programs I have been able to modify many meshes and arrive at a very printable object. If you decide to try Wings 3D you need to go through the tutorials, since there is a multitude of possibilities, including making your own meshes, beginning with several basic forms such as squares, cubes, cylinders and several other basic geometrical figures. stl format, but you may have to fine tune to get rid of holes blemishes and etc., and you can view your changes in several views such as Gaussian and other forms.

stl) and then use netfab (also has a free version with some limitations as compared to the paid version) to fine tune the mesh if it is not printable in its current format. When you have completed your modifications you can export them in one of several formats (I find it easier to just keep it in. Not only can you reform the mesh, but you also you have the ability to import and export many other meshes such as. It is very easy to use, and has many other useful functions built in. I have used Wings 3D ( ) for just that purpose. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. It is free software and available for Linux/UNIX, Windows and Mac OS X. OpenSCAD is a software for creating solid 3D CAD models.

It is hard to start with if you have never coded, but that's worth it : You can then interact with them by doing binary operations, adding parts, etc. You can also import existing STL and edit them like they were a primitive shape like a cube. On Thingiverse, a lot of things are made with this CAD software (the Customizer flagged ones) and you can just download their source code (. It's a script based powerful CAD open source software under GPL.
