2. Application of 3D printing in architecture: With the help of 3D printing technology, architects can turn design ideas or sketches into tangible objects at their fingertips, which not only saves time for manufacturing scale models of buildings, but also helps to reduce costs, save manpower and material resources, and facilitate architects to further check the rationality of architectural design, thus ensuring the safety and availability of buildings to the greatest extent.

3. Application of 3D printing of cultural relics: The original scale 3D printing and copying project of the west back room of No.3 Cave in Yungang Grottoes in Datong was successfully unveiled in Qingdao Cultural Media Group Square, which is the first large-scale cultural relics copying project realized by using 3D printing technology in the world, creating a milestone in the digital protection and inheritance and utilization of China's heritage.

4. The application of 3D printing in automobiles is based on the characteristics of rapid prototyping, and 3D printing is applied to the whole life cycle of automobiles (including R&D, production and customization). Among them, SLA photocuring prototype manufacturing is widely used in research and development as a means of design verification and evaluation before new cars are put into production. Previously, many R&D departments of domestic car companies purchased Aurora SLA industrial 3D printers for making mold samples for modeling review, design verification and performance testing.

5. Medical 3D printing application: 3D printing personalized medical auxiliary equipment can be used in orthopedics, dentistry and plastic surgery. 3D printing operation planning model, used for operation rehearsal, to improve the ability to correctly handle various emergencies and improve the success rate of operation; Moreover, the preoperative simulation model can be directly transformed into a teaching tool after the operation is completed, which becomes a favorable tool for students and young doctors to analyze the lesions.
