The latest version of Meshmixer is now ready to download for free from the Autodesk 123D App site.
MeshMixer started as a super fun and intuitive way to mash-up multiple STL or OBJ files so you could make mutant models to 3D print. With time and investment by Autodesk, MeshMixer has evolved to become an incredibly powerful tool to create, modify, color and prepare a 3D model to 3D print, and, it is still free.
With MeshMixer, you import base geometry, whether it be a simple sphere or a more complex 3D mesh such as a 3D scan you can then choose from a series of tools to sculpt the form by pushing and pulling the geometry around like virtual clay, in an organic matter in a similar way to software such as Sculptris and ZBrush. Because of this organic, sculptural surface modeling process, Meshmixer is not really suitable for 3D modeling an engineered product such as an iPhone case, a camera mount or anything the connects to another thing from scratch. You can however import an STL file of an engineered product, and add some sculptural, organic components. Or mash it up with another 3D mesh. Like so.
Meshmixer is useful way beyond making odd cups with your face scan and a monkeys leg, the post processing tools to boolean, make solid, shell, scale, pattern and paint make it a really valuable tool in your 3D arsenal.
Meshmixer integrates with Shapeways 3D printing service so you can get an instant estimate on the cost of 3D printing your model within Meshmixer, you can then upload your 3D model from within Meshmixer to your Shapeways account or save the 3D file to your computer and upload it to Shapeways to 3D print.
Version 2.5 of MeshMixer is now available to download for both PC and OSX.
