ZRapid Metal 3D Printer: Innovative Technology Supporting the Low Altitude Economy Technological advancements have brought attention to the "low altitude economy." This term refers to economic activities conducted at altitudes below 1,000 meters, where drones are utilized across a wide range of fields, including agriculture, logistics, environmental monitoring, and urban management. Among these, the manufacturing of drone frames is a crucial factor directly linked to performance and cost, supported by ZRapid's metal 3D printers. Main Benefits of Metal 3D Printers Lightweight and Structural Optimization: Improved flight efficiency and stability, extending flight duration. Integrated Molding: Eliminates the need for molds, shortens processes, and reduces costs, supporting faster market entry. Design Flexibility: Accommodates complex designs and customizations, adapting flexibly to special needs. Material Efficiency: Minimizes waste and achieves efficient production. ZRapid's "iSLM600QN" enables rapid manufacturing and powder reuse, providing lightweight and high-quality drone frames, contributing to the development of the low altitude economy.

Hello! Thank you very much for visiting us among many other sites. Our company is a specialized trading firm that focuses on non-ferrous metals and was established in 1948. Originally, we only conducted domestic business in the materials sector, but we have actively established overseas bases (in China, South Korea, and the Philippines) and have created new business opportunities in the components sector, as well as entered the 3D printing field. With an eye on the future, we are expanding our business areas, and each of our businesses is reaching a growth stage. In this context, in order to pursue further added value as a trading company, we have established a supply scheme for brass bars in collaboration with DOHO, Sugino Metal Industry Co., Ltd., and JX Metals Co., Ltd., and we will start accepting orders from April 2022. **Features of the Scheme** In this supply and sales system, DOHO serves as a consolidated point of contact as the sales agent, Sugino Metal supplies the raw material bars, and we have commissioned JX Metals, which has one of the largest plating facilities in Japan, for tin plating processing, thereby realizing this supply system. The brass tin-plated bars we supply are characterized by our commitment to a "3-month delivery time," which meets our customers' planned procurement needs.
