Electron beam 3D printing technology is a unique metal additive manufacturing technology, which has the characteristics of high energy density, fast production efficiency, low forming stress and no pollution in vacuum environment. However, there are still some bottlenecks in power, precision, cathode life and cathode cost. Recently, Xi'an Sailong, a representative enterprise of domestic electron beam 3D printing technology, has a new action.
On March 27,2023, Antarctic bear was informed, on the occasion of the 10th anniversary of the establishment of the company, Xi'an Sailong held a new product conference to launch T200 electron beam 3D printing system. A number of customers from the aerospace, nuclear industry, medical and other industries participated. Technical characteristics and advantages of T200 system were understood in detail. Relevant customers also signed cooperation agreement with Sailong.
General Manager Xiang Changshu delivered a speech to welcome all customers and express gratitude for the long-term attention, support and choice of Sailong. The company will continuously improve its technical strength, product quality and service level, and provide customers with better metal 3D printing solutions.
Manager Zhao Pei introduced T200 system in detail. As the world's first SEBM system equipped with an indirectly heated electron gun, it breaks through the contradiction between power, accuracy, cathode life and cost, and can meet needs of high-precision, low-cost and mass manufacturing of complex parts in aerospace, nuclear, medical and other industries.

Main parameters of T200:
•The build size of T200 is 200×200×450 mm that can fully exert the SEBM advantages of stacked printing. Taking φ44mm Titanium alloy acetabular cup as an example, 288 pieces can be produced in a single furnace and manufacturing time is less than 100 hours.
•The electron gun has a beam power of 6kW that can quickly preheat the powder bed of 200×200 mm2 up to 1300 ℃ above and significantly improve printing efficiency.
•The minimum beam diameter is less than 100μm that breaks the existing cognition of low build accuracy of SEBM equipment, meeting the printing need of high-precision parts.
•The filament lifespan is greater than 500 hours that can meet the continuous and long-term printing requirements for large-scale parts or mass production of parts.
•The electron gun cathode and auxiliary cathode are both made of tungsten material, which has good durability and is conducive to low-cost manufacturing of parts.
•Variable energy density preheating technology achieves uniform and consistent heating temperature of substrate and powder bed in the forming area.

According to different application scenarios, Sailong has also launched other SEBM systems that are equipped with indirectly heated electron guns, with different bulid sizes and powers, such as Y150 Plus (beam power 3kW, build size 170×170×180 mm), H400 (beam power 6kW, build size 400×400×400 mm). Related systems have been sold in aerospace and medical industry.

Since the launch of the first commercial SEBM system in China in 2015, Sailong has always been based on the frontier of SEBM system and technology. It is market-oriented and user-centered. Based on various application scenarios, it has launched multiple types of SEBM systems and formed batch sales, contributing to the rapid development of various industries. Sailong will take this new product launch conference as an opportunity to continue to refine its technology and help industrial manufacturing develop in a faster, more refined, more economical and more convenient direction.
