　　The original report is as follows:

January 5, the first of the latest generation of open source electron beam metal 3D printer QbeamLab in Tsinghua University Tianjin High-end Equipment Research Institute officially released. Professor of Tsinghua University, director of the Institute of Additive Manufacturing Technology and Engineering of the High-end Institute (referred to as "Additive Manufacturing Institute"), Lin Feng, chief scientist of Zhibeam Technology, he Yongyong, executive vice president of Tianjin High-end equipment Research Institute of Tsinghua University, Yu Lili, deputy director of Huaming High-tech Zone Management Committee, and Zuo Shiquan, deputy secretary-general of the National additive Manufacturing Industry Alliance of the Ministry of Industry and Information Technology, attended the press conference.

Selective electron beam melting (EBSM) metal 3D printing uses electron beam as an energy source to manufacture solid parts by melting metal powder layer by layer in a high vacuum environment. Due to the high power of the electron beam and the high energy absorption rate of the material to the electron beam, EBSM technology has the characteristics of high density, low oxygen content, low thermal stress, not easy to deform and crack, low price of powder consumables, and high printing efficiency. It has unique advantages and application value in 3D printing of metal materials, especially refractory metal materials, and is widely used in orthopedic medicine, aerospace and other fields. For example, many medical device companies at home and abroad, including Aikang Medical, use EBSM to manufacture orthopedic implants such as hip joints and vertebral bodies, and have successfully obtained FDA and CFDA medical registration certificates. GE uses EBSM technology to manufacture titanium-aluminum alloy low-pressure turbine blades in batches. The manufacturing cost is close to that of precision casting, and the weight is reduced by 30%. It will eventually replace all cast blades and be installed in the latest aircraft engines.

The open source electron beam metal 3D printer QbeamLab was released by Tianjin Qingyan Zhibeam Technology Co., Ltd. (hereinafter referred to as "Zhibeam Technology"), an incubator of Tianjin High-end Equipment Research Institute of Tsinghua University. It has the characteristics of core software autonomy, key components autonomy, modularization and customization, open source of process parameters, self-diagnosis and self-recovery, and long-term stability and reliability.

We must know that for a long period of time, most of the research and application of EBSM technology are based on imported equipment and platforms, and domestic independent equipment is in a blank. In 2004, the technical team led by Professor Lin Feng of Tsinghua University began to aim at EBSM technology, successfully developed the first experimental system EBSM_150 in China, and obtained the national invention patent. In 2015, more than ten years of technological achievements were transformed, Zhibeam Technology was established and 10 million yuan of financing was completed. Now, after years of research and development, finally in the country to take the lead in the introduction of open source electron beam metal 3D printing QbeamLab.

The reporter learned that once the QbeamLab equipment was launched, it has received 4 orders in 2017, including well-known companies and vocational colleges such as China Shipbuilding Industry Corporation and Tianjin Vocational University. It is worth mentioning that in the first year of the product launch, it won an order from a well-known overseas enterprise, and successfully realized the export of domestic high-end metal 3D printers. At the press conference, some orders, such as Shaanxi Hengtong Intelligent Machine Co., Ltd. and Hunan Yishu Intelligent Manufacturing Co., Ltd., signed contracts.
