The development of 3D printing technology has a profound impact on the production mode of manufacturing and the life way for people. The 3D printing strategy has been deployed by major developed countries one after another. The application effect of 3D printing has significantly increased and industry scale is growing because of the constant emergences of new 3D technology，new material and new products. In the future，3D printing manufacturing mode and the traditional manufacturing mode will coexist for a long time and go through a fusion development. The 3D printing equipment will be more universal and intelligent，the material types and performance will be more diversified，and the production mode tend will be distributed and agile. Compared with foreign countries，there are still large gaps in the 3D printing technology basic theory，technology，materials research and the core components. in our country，and the whole industrial scale is smaller. There is an urgent need to build and improve the 3D printing industry ecosystem，promote innovation upgrade with the Internet as an opportunity，actively promote the research and application of industrial 3D printing technology，support developing the product design software for 3D printing，encourage the development of personalized custom services，and promote the rapid development of industry.
