MIT researchers are developing small magnetic cubes that can communicate with each other to auto-duplicate objects in a “sand box” using a subtractive production algorithm.
3D printing is the process of making three dimensional solid objects from a digital file. Typically, this printing is achieved using additive processes, where an object is created by laying down successive layers of material. It is considered distinct from traditional machining techniques which mostly relied on the removal of material by drilling and cutting. [Read more…]
