3D printing, also known as additive manufacturing, has been closely integrated with new types of networks, advanced materials, and digital manufacturing in recent years due to its unique advantages, gradually becoming a core key technology in the new industrial revolution. Our city's 3D printing related technologies started at the end of the last century. After years of development, we have established a certain foundation in 3D printing materials, equipment, and processes, with an annual service revenue exceeding 100 million yuan and serving over 200 domestic users. However, overall, our city's 3D printing industry is still in its infancy, occupying a relatively small share of the national market and lagging significantly behind advanced countries and regions.

To narrow this gap, the Municipal Commission of Industry and Information Technology has formulated and issued the "Tianjin 3D Printing Industry Development Three-Year Action Plan (2018-2020)", proposing to strengthen the collaborative innovation mechanism of industry, academia, research, and application, and to improve the technological level of 3D printing manufacturing processes with significant demand and broad application prospects. Focusing on the major needs of our city's aerospace, automotive, and medical industries, we will increase investment in material preparation, focusing on high-quality metal 3D printing dedicated material preparation technology, breaking through the technical bottleneck of material deep processing, adapting to the needs of future industrial development, and accelerating the independent research and development and innovation of high-temperature refractory materials, high-strength materials, and optoelectronic functional materials.
