The wide application in special fields is a remarkable feature of 3D printing technology. In the medical field, especially in bone reconstruction, 3D printing technology is widely used. If the patient's pelvis has been necrotic, the Ninth People's Hospital affiliated to Shanghai Jiaotong University printed an artificial bone pelvis in 3D and successfully transplanted it into the patient's body, and finally the patient recovered successfully.
Of course, it is also widely used in the aerospace field. 20 16 In April, European aircraft manufacturer Airbus received the LEAP- 1A engine of its next generation Airbus A320neo, which means that they officially used the alloy fuel nozzle printed in 3D for aircraft engines.
Personalized customization is one of its great advantages. Traditional industrial manufacturing is mass production, which can ensure that the product cost is low enough; Otherwise, ordinary people can't afford it, products can't be sold, and there is no market. However, the emergence of 3D printing technology makes personalized customization possible.
On the one hand, modeling and printing technology make it possible to reduce the cost, on the other hand, the cost is directly proportional to the size and volume of customized parts. In other words, the cost of things with the same volume and the same material is not much different. From the perspective of mass production, the cost of modeling is shared equally, which makes the cost of mass production and single-piece production have little correlation.
Among them, 3D printing is the most important part of the plan. In the full text of the plan, * * * appears six times, which runs through important paragraphs such as background introduction, promotion of national manufacturing innovation capability, deep integration of informatization and industrialization, and breakthrough development of key areas. , and integrated into the main line of promoting intelligent manufacturing, which reflects China's emphasis on 3D printing and shows China's profound understanding of the situation and environment faced by manufacturing development at the strategic level. Although "3D printing" has incomparable advantages over traditional manufacturing methods, its development is actually restricted by some defects.
The cost is higher. High-precision 3D printers are relatively large and expensive, and the technical patents are basically in the hands of foreign companies, so it takes a lot of money to purchase and obtain technical licenses. From the perspective of 3D printing applications, it is mainly used in aerospace, human organ medicine, antique accessories and other industries, which are all high-end manufacturing industries.
