3 d printing is also called a "material" made Additve (Manufacturing) technology, based on the computer model based on 3 d design, through software hierarchical discrete and nc forming system, using a laser beam, hot nozzle way such as plastic, metal powder, ceramic powder, and other special materials accumulated the massive tissue bond, superposition forming, eventually create physical product Manufacturing method. 3D printing is a manufacturing process different from traditional processing methods, which can be roughly classified as follows:
Application of 3D printing under practical conditions division of 3D printing
First, we need to make it clear that 3D printing, as a "generic name" for additive manufacturing, usually refers to a class of manufacturing technologies, not just any one of them. Secondly, there is usually an international classification of 3D printing equipment, which usually sells for $5,000 or more and is called "industrial" 3D printing equipment, while those below $5,000 are "consumer" or "desktop" 3D printing equipment. At present, consumer-grade equipment is mainly concentrated in the fields of education, maker and simple model making, while industrial-grade equipment has a broader application field and prospect.
Main Application areas
As can be seen from the figure, industrial 3D printing is mainly used in transportation, aerospace, industrial equipment, consumer electronic products and medical treatment in the world. Due to the lack of specific information, the application of 3D printing in China, from the perspective of personal feelings, has accumulated a solid foundation and expanded its scale in the space field. In the medical field, 3D printing has been widely used in dentistry, and the manufacturing scale of metal implants is expanding. In the industrial field, 3D printing injection mold application is still relatively large scale. In other aspects, more use 3D printing in the development stage of the sample trial production, and some hand parts of the printing.
Major Industry Cases
The additive manufacturing characteristics of 3D printing have endowed it with application potential and prospect in various industries. However, due to the different concerns and demands of various industries, the requirements for 3D printing are also different. We can take a detailed look at the cases of 3D printing in various industries.
In this area, and more are some market-oriented enterprises, in addition to the advantage of 3 d printing manufacture technology interested in additional, at the same time also very concerned about cost, so in the field of transportation, using 3 d printing to explore and develop much more than the batch application, of course, there is 3 d printing their own cost and the influence of batch capacity constraints. For some plastic 3D printed parts, it is more used in the development and verification of some parts.
New energy battery cooling system
In the aerospace field, due to the requirements of weight reduction and strength, the proportion of complex structural parts or large heterogeneous parts in the aerospace equipment is increasing, which is the advantage of 3D printing. Meanwhile, in the aerospace field, it is highly sensitive to the performance requirements of parts and relatively insensitive to the price, which is also conducive to the adoption of 3D printing technology (mainly metal 3D printing).

(3) Industrial equipment
In the field of industrial equipment, there are more injection mold core printing, some non-standard equipment parts manufacturing, and the application of production line auxiliary tooling.
Formation-dependent waterways in molds (better cooling effects)
The shaft of the laser marking machine
(4) Consumer goods
In the field of consumer goods, the customization advantage of 3D printing is more used to endue products with more personalized features to attract different groups of people.
Custom shaver handle
Custom glasses frames
(5) Medical treatment
Medical devices, especially customized medical devices, are a field that perfectly matches the characteristics of 3D printing. At present, they have a good prospect in dentistry, orthopedic implants, rehabilitation orthotics and other aspects.
Dental mold, directly printed metal crown
Hearing aid housing (fitting the ear canal)
(6) Scientific research & Architecture
In addition to the above five main fields, other fields are no longer listed as examples. In simple terms, they are the frontier and expansion of 3D printing in the field of scientific research, including bio-printing and research on new materials, etc. They do not know much about architecture, and I personally think they are more similar to the idea of 3D printing.
Looking forward to
Each technology has its own advantages and limitations, and will adjust its development curve according to the market demand, as 3D printing does. Nowadays, with the promotion and use of 3D printing technology, it has been accepted and recognized by most countries, regions and industries. In addition to the subsequent change in design thinking, the enrichment of material types, the improvement of technology maturity and the reduction of costs, it will become a very important supplement to the traditional manufacturing industry and become an emerging production industry and new production technology, promoting the transformation and upgrading of the traditional manufacturing industry
