Latest Patents

Jun Duan holds a patent for a "Rapid prototyping and tooling system." This invention involves a solid freeform fabrication process and apparatus designed for making three-dimensional objects. The process includes operating a material deposition sub-system that dispenses droplets of solidifiable liquid compositions onto selected spots of an object work surface. A focused heat source maintains a heat-affected zone on the work surface, creating a weld pool of molten materials by injecting selected powder particles into this zone. The deposition sub-system and work surface move relative to each other in an X-Y plane and a Z direction, allowing for the formation of multiple layers to create a three-dimensional shape. The system is controlled by a computer, which also generates support structures for unsupported features of the object.
