Taiwan Institute of Research and Development has developed a high-power laser metal 3D printer
3D printing technology has become a battleground for the global manufacturing industry. On October 6, 2015, Taiwan’s Zhongshan Institute of Science and Technology released a self-made metal 3D printer system with a 500-watt high-power fiber laser. According to Ren Guoguang, deputy director of the Institute of Missile Rocket Research, this Taiwan-developed metal additive manufacturing system (metal 3D printer) is comparable to the same level of global fiber laser manufacturing leader IPG. Between, initially meet the aerospace grade material use standards (AMS-6514); next year is expected to develop a 1K watt metal 3D printing system, the overall technology hopes to be able to keep pace with international manufacturers after one year.

Ren Guoguang pointed out that at present, the Chinese Academy of Sciences has already carried out 3D printing on the discontinued parts supplied by Hanxiang Company. In addition, this system can accelerate the lightweight and micro-chemical development of the self-developed missiles in the future, which will help Taiwan's defense industry to improve. And can create a new era of aerospace and additive manufacturing.
The 3D metal printing system planner Ren Guoguang said that after the 3D metal printer is self-produced, the next step is to develop metal powder technology. It is expected that Taiwan will develop its own powder within half a year, develop different powders according to different aerospace components, and apply it in aerospace. And the defense industry.
Ren Guoguang said that the additive manufacturing verification platform made by Taiwan Academy of Sciences can process dimensions of 250×250×300 mm and the forming precision is less than 50 μm. The metal parts produced by the anti-aging steel material (before thermal modification) have a tensile strength of 1,100 megapascals (MPa), a relief strength of 950 megapascals, and a hardness of more than 30 (HRC), which is initially compatible with aerospace grade materials. The standard (AMS-6514) can be used on the aircraft after passing the FAA certification in the future.
Ren Guoguang said that 3D metal printers can solve the problem of parts manufacturers often encounter in the service system of weapons systems. As long as the materials are analyzed first, the same metal powder is used, and then according to the design drawings and dimensions, you can try to print with 3D metal. It can be used after it has been tested and tested for hardness, strength and compressive strength. Therefore, in the future, the components of the sea dragon and sea tiger submarine that are used in the Taiwan Navy will not be excluded.
In addition, the various types of missiles of the Xiongfeng, Tiangong and Tianjian series developed by the Chinese Academy of Sciences in Taiwan can use 3D metal printers in the future to reduce the volume and weight of the missiles. , add other equipment, enhance its range and performance, and assist in the upgrade of missile technology.
