3D (three-dimensional) printing rapid forming device based on magnetorheological material

The utility model relates to a 3D printing rapid forming device based on a magnetorheological material. According to a magnetorheological effect principle, the magnetorheological material is taken as a 3D printing raw material; the magnetorheological material is injected into a working platform provided with a magnetic field, solidified and formed rapidly; then deposition is performed layer by layer, so that a 3D entity model is constructed; a computer is provided with three control circuits; one circuit controls the flow, namely the flow at a spray nozzle, of a driving pump; one circuit controls the spray nozzle to move three-dimensionally through a servo mechanism; and the other circuit controls the colored cartridge deployment; and the magnetorheological material are solidified and formed by magnetic field produced by a electromagnet. According to a magnetorheological effect of the magnetorheological material, the 3D printing rapid forming device replaces a temperature control module in a conventional fusion injection rapid forming 3D printing method with the magnetic field which is also different from a high voltage electric field in an electrorheological fluid effect. The device has the advantages as follows: the structure is simple, the energy consumption and the cost are low, microminiaturization can be realized, and the like. The device can be applied to fields such as process design, art entertainment, prosthesis models and the like.
