There is no need to use traditional molds, knives, fixtures and machine tools of resin, nylon, gypsum, plastic, steel slag, ceramics, sand and other materials. anyhow. Additive manufacturing (also known as 3D printing) technology, also known as rapid prototyping technology. With the development of the industry, support for titanium, stainless steel or aluminum, and iron metal materials has emerged. According to the three-dimensional model data of the part or object, it is input into the computer, and the physical model is established by the material stacking in the molding equipment. Pressing the print button, the laser can selectively sinter raw materials into various objects, including complex industrial parts, house structures, pots and pans in life.
3D printing technology is a major technological revolution in the manufacturing field. It changes the processing method of raw material cutting and assembly, and can be produced according to different needs anytime, anywhere. 3D printing is a major leap forward in the field of science and technology represented by digital manufacturing, new materials and new energy applications. It is a perfect combination of traditional manufacturing technology and new materials. It has been widely used in the military field, such as aerospace and the formation of large and complex components. Today, the world’s first 3D printed car was launched in Canada, with a top speed of 112 kilometers per hour. European scientists can “print” bicycles, even houses, human organs, etc.
As one of the most compelling technologies in Industry 4.0, 3D printing is developing rapidly around the world. In recent years, my country has paid more attention to the development and application of 3D printing technology. “Made in China 2025” lists 3D printing technology as a key development area. At present, metal 3D printing technology has been successfully applied in high-end manufacturing fields such as aerospace, military, medical, etc. It has unique advantages in quality, efficiency and cost. The main challenges facing metal 3D printing technology.
