Nanjing Aerospace Opto-Electronics Hi-Tech Co., Ltd, belongs to Tianjin Jinhang Technical Physics Research Institute. It develops from the Nanjing R & D center of the institute. The center was established in July, 2014, and developed into the Nanjing company in December, 2015. It is located in the Innovation Science Park in Nanjing Economic & Technological Development Zone. The company mainly focuses on the R & D, production and sales of the 3D printers. By far, it has mastered the core technology of FDM 3D printing with high accuracy and speed. The hardware and software of the 3D printers are all developed by the company itself and it has applied successfully many technological patents and the software copyright. Its different types of 3D printers have come into the market, and could print the materials including PLA, ABS, PETG and PVA. These printers have passed the CE test, and are sold well not only at home but also abroad. Except the FDM 3D printers, the company still has the 3D printers for PCB board and for metal under experiment.

Tianjin Jinhang Technical Physics Research Institute, one of the earliest organizations researching optoelectronic technologies and applications in China, is the central institute on the infrared and laser technologies for aviation industry. It belongs to the China Aerospace Science & Industry Corporation. The institute has rich technological and talent resources in the areas of infrared imaging, laser, optical navigation, optical load, optical design and manufacture and special optical electronic devices. It also has much R & D experience on complicated optical electronic products.

The research and application of 3D printers will promote the development of manufacturing industry. Tianjin Jinhang Technical Physics Research Institute has cooperated with Nanjing University of Posts and Telecommunications, Tianjin Polytechnic University, CAS Institute of Chemical and Xi'an Institute of Optics on 3D printing. Nanjing Aerospace Opto-Electronics Hi-Tech Co., Ltd is thereafter established for the research and sales of 3D printers.
