      Chinese scientists leverage metal 3D printing to upgrade traditional material manufacturing industry

      Researchers at a laboratory in Foshan City, south China's Guangdong Province, have deepened their research on metal 3D printing technology, also known as metal additive manufacturing, to upgrade the traditional materials manufacturing industry.

      Metal 3D printing is a laser-based technology that constructs objects layer by layer by fusing metal particles. It employs heat or light energy, such as a laser or electron beam, to melt or bond the metal powder, spreading it over previous layers.

      According to a researcher at the Institute of Advanced Additive Manufacturing of Ji Hua Laboratory, 3D printing has a great advantage in fabricating arbitrary shapes without any limitations and has great potential in preparing controllable porous structures.

      "In traditional methods of processing, we need to produce these channels first and then weld them at the corresponding points, which can result in tiny welding defect pores in the welding area. However, 3D printing completely avoids the possibility of welding defects because it is integrally formed. Our whole industry is gradually developing in the direction of larger sizes, more lasers, and higher efficiency," said Gao Chaofeng, doctoral student at the Institute of Advanced Additive Manufacturing of Ji Hua Laboratory.

      Another researcher at the lab pointed out that they aim to make more progress in new material and key components development in some key areas.

      "We aim to solve some of the main difficulties in the industry at present, such as improving the quality and performance of products and reducing costs. In the long run, we strive to develop new materials and future technologies in China, especially in equipment such as key components for engines and aerospace fields," said Bi Yunjie, deputy director of the Institute of Advanced Additive Manufacturing of Ji Hua Laboratory.

      Ji Hua Laboratory is one of the first four provincial-level laboratories initiated by the Guangdong Provincial Party Committee and the Provincial Government. Since its establishment more than six years ago, the laboratory has mainly focused on new display equipment, semiconductor equipment and key components, intelligent robots, high-end medical equipment, advanced remote sensing equipment, additive manufacturing equipment, and new materials and devices.

      China's domestic travel market sees strong growth in 2024

      China saw a significant surge in domestic travel in 2024, with a total of 5.615 billion trips recorded, representing a 14.8 percent increase from the previous year, as reported by the Ministry of Culture and Tourism on Wednesday.

      Domestic travelers in China spent a record-breaking 5.75 trillion yuan (about 790 billion U.S. dollars) during the year, up by 17.1 percent from 2023, the ministry said.

      According to the quarterly breakdown of domestic tourism data, the first quarter saw a remarkable 16.7 percent surge in travel, with 1.419 billion trips recorded. The second quarter followed with 1.306 billion trips, representing a year-on-year increase of 11.8 percent. The third quarter experienced another surge, with 1.512 billion trips, a growth of 17.2 percent compared to the same period last year. The fourth quarter concluded with 1.378 billion trips, a 13.2 percent increase from the previous year.

      Urban residents made up the majority of domestic trips, with 4.370 billion trips taken, reflecting a robust 16.3-percent growth compared to 2023. Rural residents recorded 1.245 billion trips, showing a more moderate but still positive growth of 9.9 percent.

      Accordingly on the expenditure front, urban residents were the primary drivers of domestic tourism, contributing 4.93 trillion yuan, an 18.0-percent increase year on year. Meanwhile, rural residents spent 830 billion yuan, reflecting a growth of 12.2 percent.
