In theory, the 3D printer is not just a copy a work machine, it is a robot. For the production of three-dimensional physical machines, there are several different implementation technologies. Some 3D printers use tiny liquid particles, plastic and metal, slowly “print” three dimensional computer models. Some 3D printers use liquid plastics polymer curing. Some carved in the synthetic material.
Walt Disney invented a 3D printer, laser cut fabric into layers, and then glue each layer, made into a flexible fiber models–is dolls. The allure of this 3D printer is not fast, but you can control the model flexibility. By adding or removing the internal layer of the model, the bending direction of control model, not tilted to the other side. For example, producer-shaped doll, dolls are often bent forward, and not leaning. When making a costume or decorations, a joint of the body fabric folding, not ideal.
Because building a layer at a time, can be placed between layers of electronic components. Now, Disney has not released any results of practical application, only outlined the prospects. Sensors can react to touch between the layers. If the two layers together, you can make touch slider. In other words, Disney can be placed in a fabric print objects multi-touch trackpad.
