3D printing starts from fine materials and uses digital control as a means to transform the traditional serial process of material selection, preparation and process processing into a parallel process of formation and forming.
3D printing, also known as additive manufacturing, is a manufacturing process in which materials are formed layer by layer under computer control. Although it has a development history of 30 years, it is still an emerging technology in the field of industrial manufacturing, and it is also regarded by the industry as an important technology for the next industrial revolution.

3D printing starts from fine materials and uses digital control as a means to transform the traditional serial process of material selection, preparation and process processing into a parallel process of formation and forming.

  3D printing + auto parts

Recently, the BMW Group announced good news that the IDAM (Industrialization and Digitization of Additive Manufacturing) project jointly launched with 12 partners has been successful, and two fully automatic 3D printed car production lines are about to be put into operation. One of them, at the BMW Group's Munich plant, uses laser powder bed fusion (LBPF) combined with artificial intelligence and robotics, enabling serial production of around 50,000 identical parts and more than 10,000 individual and spare parts per year.

This project was actually started three years ago, and it has been successful so far, which further indicates that 3D printing technology has been deeply applied to the field of automobile manufacturing.

According to the forecast of foreign SmarTech Analysis, from 2021 to 2030, the application of 3D printing in the automotive industry will grow at a rate of 19.1%, and the use of 3D printing in the automotive supply chain will further increase.

  3D printing + satellite antenna technology

Mitsubishi Electric Corporation has announced that it has developed an in-orbit additive manufacturing technology that uses photosensitive resin and solar ultraviolet light to 3D print satellite antennas in outer space.

The European Space Agency also announced last year that it will use metal from the moon to conduct 3D printing experiments in space. With more and more related space additive manufacturing technologies, there may be one more way to reduce the cost of satellite launch, and it will also provide components for future space missions. Bring other design and manufacturing methods.

  3D printing + buildings

On May 9, 2022, the International Invention Patent "Apparatus and Method for Preparing Building Structures Based on 3D Printing", which was applied for by the Cement New Materials Institute of China General Research Institute of Building Materials Co., Ltd. through the Patent Cooperation Treaty, was granted the patent right by the US Patent and Trademark Office. .

The international patent authorized this time is not only the first US patent in the field of cement concrete 3D printing by China National Building Materials Institute, but also the first in the world to propose a complete set of technologies including "U-shaped reinforcement" and "shooting nails". patent.

According to related reports, China is using artificial intelligence to essentially turn the Yangqu Dam project on the Qinghai-Tibet Plateau into the world's largest 3D-printed building.

The construction is very complex because of the process of steel, concrete and so on. Compared with traditional reinforced concrete, the advantage of the 3D printing slice construction method lies in the topologically optimized distribution of concrete materials, which more efficiently exerts the compressive properties of concrete materials.

In China, it is rare that the entire project adopts 3D printing technology. But I am convinced that with the widening and deepening of the application range, 3D printing will show great potential in the construction industry.

At present, China attaches great importance to the development of 3D printing technology. In 2021 alone, various ministries and local governments have issued 23 relevant policy documents. The future of 3D printing technology can be expected, and more companies are expected to enter!
