Beijing 3D Printing Technology, Inc. is national high-tech and Beijing SRDI enterprise. We are 3D printing overall solution provider with technology of "SLS+SLM+3DP+BJ" process focusing on green and rapid manufacturing. The business covers finished parts manufacturing, 3D printing equipment and raw material R&D and production also the technical support services etc. It has established a complete 3D printing rapid manufacturing industry chain, which is widely used in aerospace, military industry, high-voltage electrical, engineering machinery, ship pumps and valves, automobiles, rail transit, 3C electronics, education and scientific research, sculpture culture and creativity, rehabilitation and medical industries. In 1994, It's subsidiary company Beijing Longyuan AFS successfully developed the first commercial industrial-grade 3D printer with independent intellectual property rights in China. On the basis of years of 1.0 equipment and applications, 3D printing Technology has independently mastered the 3DP and BJ line high-speed scanning 3D printing 2.0 equipment, materials and processes, which can meet the manufacturing needs of different sizes (from millimeters to meters). We independently developed SLS selective laser sintering , SLM selective laser melting, 3DP sand printing, BJ binder jetting metal/ ceramic printing etc. series of intelligent equipment . We deeply developed nearly 30 kinds of material process formulas suitable for aluminum, copper, iron, magnesium, steel casting and other casting fields and more than 20 binders in 5 series. Through more than 10 intelligent manufacturing centers across the country, as well as 3D printing rapid casting demonstration factories in Shaanxi, Shandong, Anhui, Hebei, Guangxi and other places, it has established full-size, multi-material, full-link rapid manufacturing service capabilities, which can provide users with rapid finished parts manufacturing, complex sand mold, sand core, wax mold printing, sand printing rapid casting, wax printing precision casting and other services.As a practitioner of new quality productivity, 3D Printing Technology actively promotes the large-scale application of 3D printing industrialization and empowers manufacturing with science and technology based on the independent technology of 3D printing equipment, materials as well as processes. Through the acquisition of foundries, the "3D printing + casting" process is opened as a demonstration model that can be replicated and promoted. By helping traditional foundries upgrade to green, intelligent and high-end casting, we applying 3D printing 2.0 technology to improve powder injection molding so as to realizing moldless rapid mass manufacturing. We drive the 100 billion-level rapid manufacturing market with improving quality and efficiency that promoting high-quality development, transformation and upgrading of traditional manufacturing. "Multi-process Combined Sand Mold Manufacturing of Key Components of Aero Engine" and "Batch Manufacturing of Binder Injection for Aluminum Alloy Piston Mold for Internal Combustion Engine" were selected as typical application scenarios of additive manufacturing by the Ministry of Industry and Information Technology in 2023.Relying on the "Trinity" collaborative innovation system of Guoqian Science and Technology Research Institute, postdoctoral workstation and enterprise R&D team, 3D Printing Technology and its subsidiaries have applied for nearly 300 patents and copyrights, and have successively passed ISO 9001 quality management system, ISO 13485 medical device quality management system, ISO45001 occupational health and safety management system, ISO14001 environmental management system, CE, EAC and other certifications, and obtained Class I and Class II medical device access qualifications. We have participated in the drafting of a number of national and industry standards, and has released 3 national standards.
