Where is 3D printing technology mainly used?

The application fields of 3d printing mainly include: architectural design: In the construction industry, engineers and designers have accepted the architectural models printed by 3D printers, which are fast, low-cost, environmentally friendly and beautifully made. It completely meets the requirements of designers and can save a lot of materials at the same time. Manufacturing industry: The manufacturing industry also needs many 3D printing products, and 3D printing is much better than traditional manufacturing industry in terms of cost, speed and accuracy. 3D printing technology itself is very suitable for mass production, so the use of 3D technology in manufacturing industry can bring many benefits. Food industry: researchers have begun to try to print chocolate, which can be made into various shapes. Industry: Large industrial enterprises have begun to use 3D technology to print metal powder and laser forming. Jewelry industry: At present, 3D printing technology has been applied to the jewelry industry, which can manufacture various styles of jewelry. The course "3D Printing Technology and Application" is the first large-scale online open course and national excellent online open course offered by Northwestern Polytechnical University, a large-scale open online course branch of China University, on March 17, 2007. The teacher of this course is Wang Yanen. According to the introduction of official website 20021March, a large-scale open network course of China University, the course is taught in five chapters and seven times, including the historical evolution of 3D printing technology and its relationship with additive manufacturing, the manufacturing process principles of various 3D printing technologies, the pretreatment technology and principles of additive manufacturing of 3D printing technology, the post-processing technology of 3D printing technology and the application of 3D printing in various fields.
