A few years ago, 3D printing technology became popular, and the entire society was discussing it. Many universities took advantage of this opportunity to open related majors, and many local governments were involved in financial subsidies, land supply, loan interest discounts, and water and electricity prices. Very generous policies have been introduced in various aspects.
The extensive application in special fields is a distinctive feature of 3D printing technology. In the medical field, especially in bone reconstruction, 3D printing technology is widely used. For example, if a patient's pelvis has become necrotic, the Ninth People's Hospital of Shanghai Jiao Tong University 3D printed a pelvis using artificial bone materials and successfully transplanted it into the patient's body, and the patient eventually recovered successfully.
Of course, it is also widely used in the aerospace field. In April 2016, European aircraft manufacturer Airbus received the LEAP-1A engine for their next-generation Airbus A320neo passenger aircraft. This is the official time they will use 3D printed alloy fuel nozzles for the aircraft engine.
Personalization is its great advantage. Traditional industrial manufacturing is all about mass production, so that the cost of the product can be kept low enough; otherwise, the people will not be able to afford it, and the products will not be sold, and there will be no market. But the emergence of 3D printing technology makes personalized customization possible.
On the one hand, modeling and printing technology make it possible to have lower costs. On the other hand, the cost is directly proportional to the size and volume of the customized parts. This means that for things of the same size and material, the cost difference is not big. From the perspective of mass production, the cost of modeling is nothing more than the cost of modeling, which makes the cost of mass production and single-piece production irrelevant.
Among them, 3D printing is the top priority of the plan. It appears 6 times in the full text of the plan, throughout the background introduction, improvement of national manufacturing innovation capabilities, deep integration of informatization and industrialization, Important paragraphs such as breakthrough development in key areas, and integration into the main line of promoting intelligent manufacturing, reflect the importance my country attaches to 3D printing, and demonstrate my country's deep understanding of the situation and environment facing the development of the manufacturing industry at the strategic level. Although "3D printing" has unparalleled advantages over traditional manufacturing methods, some of its shortcomings have actually restricted its development.
The cost is higher. High-precision 3D printers are relatively large and expensive, and technology patents are basically in the hands of foreign companies. It costs a lot of money to purchase and obtain technology licenses. From the perspective of 3D printing application fields, it is mainly used in aerospace, human organ medical treatment, antique accessories and other industries, which are all high-end manufacturing industries.
