Dr. Zong Guisheng said that at present, the global manufacturing challenges are escalating and the manufacturing industry is changing faster than ever. In order to stay in the competition, we need to improve efficiency (especially energy and resource efficiency), shorten time-to-market (shorter development time, ability to manufacture complex products, ability to quickly access and analyze big data), and increase flexibility (large number of personalized products, rapidly changing markets, high productivity requirements), which drives the development of smart manufacturing.

　　The combination of ICT technology and manufacturing gives rise to smart manufacturing. Walking into a future smart manufacturing factory, you can see a variety of independent devices (e.g., 3D printing) that are connected, constantly open, intelligent, software- and data-controlled; machine-to-machine and machine-to-product communication is all about human interaction; the Internet of Things (IoT) triggers and provides information and data for decision-making; information is processed and transmitted in real time; and staff members can make decisions on their own or as a group (societal group decision-making), and the entire industrial ecosystem is going to The entire industrial ecosystem will change profoundly.

　　3D printing, one of the core technologies of smart manufacturing, has a huge potential to transform the entire production industry. It creates a whole new ability to produce items of various shapes and sizes, enabling engineers to design more complex products that could not be realized before.3D printing is widely used in rapid prototyping in aerospace, automotive manufacturing, foundry, medical, civil and other fields due to its advantages of manufacturing complex parts, product diversification without increasing costs, assembly-free, cloud manufacturing, zero-skill manufacturing, portable manufacturing, net molding, etc. , rapid manufacturing. Looking to the future, we apply 3D printing thinking to design and manufacture products, and embrace intelligent manufacturing.

　　The combination of 3D printing devices and the Internet has led to innovations in business models. For example, online platforms that provide 3D printing services and transactions - Shapeways, Ponoko, i.materialise, Everything Print (www.wanwudayin.com), etc. Through these sites, users can purchase design models, order 3D printed products, or open their own stores to sell 3D printed products, designs or materials. This new business model is called D2C - Designer to Customer, and it not only fulfills an individual's desire to create, but also translates into commercial profitability, which in turn will surely further drive the growth of personal 3D printing demand. What Chris Anderson calls "creativity" is the key to the success of 3D printing. Anderson said the "creators" era is step by step into reality.
