Mash your meshes together with a free, fun tool.
Meshmixer, currently a hot topic on Thingiverse, is a versatile little program for mashing up and blending meshes with little to no hassle. It’s intuitive, versatile, and even has some tools for repairing finicky non-manifold meshes.
Check out their Youtube stream for tutorials, demos, and cool ideas. Ryan Schmidt, the programmer behind Meshmixer, is continuously developing new releases, so don’t be surprised if there’s new functionality in a few months.
I spoke with him recently about creating tools for repairing finicky and self-intersecting geometry to prep it for printing and it looks like we might be seeing a powerful addition to the 3d printing software library soon!
