Questions tagged [3d-printing]

3D printing is a process of making a three-dimensional solid object of virtually any shape from a digital model. Mathematica makes it possible to take complex algorithmically generated geometry and immediately output it for 3D printing--allowing the creation of physical 3D objects and models. Mathematica also provides broad support for importing arbitrary 3D scanning data for immediate analysis and visualization.
