With the development of 3D printing technology, all kinds of new technologies emerge as the times require. There are more and more usable materials and wider application fields. Today, 3D printing technology is no longer so high, has gradually entered the public view, can benefit more people. So, what is the principle of 3D printing? What are the application fields? The following is a brief introduction.

Principle of 3D printing

3D printing is a cumulative manufacturing technology, and skill formation technology can also form digital models, using fusible materials such as wax, powdered metal or plastic to make layer by layer. At present, 3D printers are mostly used to make products, which are constructed by layer printing. The most direct principle is to put the data and raw materials into the 3D printer, and the machine prints the model layer by layer according to the program.

The biggest difference between 3D printers and ordinary printers is "ink". The "ink" of 3D printers is consumables, which can be used as raw materials for 3D printers, from plastics to metals, ceramics and rubber.

3D printer applications

1. Medical field

In recent years, 3D printing technology has been widely used in medical field. Based on medical image data, using 3D printing technology to make human organ model has great application value for surgery.

2. Mould manufacturing



The traditional mold production time is long and the cost is high. However, the combination of 3D printing technology and traditional mold manufacturing technology can greatly shorten the development cycle of mold manufacturing and improve productivity, which is also an effective way to solve the weak link of mold design and manufacturing.

3. Education industry

The application of 3D printing technology in domestic education should be the most popular. Many colleges and universities are exploring 3D printing technology and teaching, offering characteristic courses of 3D printing, and stimulating the application of 3D printing technology in education. With the development of 3D printing in the field of education, the social awareness of 3D printing is getting higher and higher. I believe that in the future, 3D printing technology will be widely used in the field of education.

4. Auto parts

3D printing technology can be used in automobiles to make conceptual models in hours or days. Complex structures can be formed at one time to meet the requirements of assembly and disassembly. In the traditional manufacturing process, complex structural parts have always been the bottleneck of production technology. However, if 3D printing technology is used, this is not a problem at all. As long as 3D printing with careful material selection can solve the problem perfectly.

5. Aerospace

Not long ago, the important parts of aerospace engine were successfully printed by using 3D printer. Compared with the traditional technology, the products printed by 3D printer must reduce the cost by 30% and shorten the cycle by 40%. This will be a new journey in the field of aerospace.

In fact, the application of 3D printing technology is far more than the above five fields. If you have other views and opinions, please contact us for discussion.
