Reducing material manufacture: The traditional machining method is "reducing material manufacture", in the process of its manufacturing materials gradually reduced, corresponding to the increase in material manufacturing, and other materials manufacturing, 3D printing brings a lot of equipment and product redesign, to get rid of the previous processing methods to the designer to bring the constraints, to create a very large space for innovative design. The car, which includes more than 20,000 parts, may also become dozens of pieces, greatly simplifying the production process, saving costs, and possibly increasing the speed of manufacturing. Jet engine Nozzle, GE has 20 parts set into a part manufacturing, fuel efficiency increased $number, 3D printing at the same time opened up a new production model and the demand for reducing materials manufacturing, the surface processing defects of the material is still very obvious, It is necessary to grind polishing equipment to the surface of the workpiece produced by adding materials, the trend of 3D printing is moving from specialization to socialization, from product development tools to mass production manufacturing means, it is possible to get breakthroughs in aerospace first. In addition, from the control of the manufacturing to control-form control, from 3D printing to 4D printing, smart materials, printing can also change the shape. 5D printing, change can also give it life, the human body's active organs can be 3D printing method of rapid customization. Reducing material manufacturing (fluid precision polishing industry) from the technical concept of three to the industrial benefit of the three points of the world.
