ITRI Presents First Indigenous 3D Metal Printer with Eye-Catching Golden Ornaments "Printed"

ITRI's 3D Metal Printer

ITRI presents the first indigenous 3D metal printer and printing materials. Cooperating with Tainan City Jewelers' Association and integrating the talent of domestic designers, over 50 pieces of cultural creative gold crafts made by 3D printing technology have been introduced by ITRI. In comparison with its imported foreign counterpart, ITRI's 3D metal printer can significantly reduce cost by 50 percent, and will be provided to the domestic industry to develop and trial-produce a variety of gold ornaments and work pieces. Tongtai Machine & Tool Co., S-Tec Corp. and Chia Yi Steel Corp. are expected to work with ITRI to produce 3D metal printer and printing materials, prompting the development of 3D printing industry of Taiwan.

Jon S. Hsu, Executive Director of ITRI Southern Region Campus, indicates that nowadays the raw materials used in 3D printing have been expanded from plastic to metal, so that its industrial application is not restricted to the manufacturing of prototypes. It now has entered the realm of directly producing goods and components with complete functions. The 3D metal printing can be used in industry sectors as diverse as aerospace, automotive, medical, mold, jewelry and other consumer goods.

With the metal powder melted by laser and stacked into shape layer by layer, the 3D metal printer developed by ITRI can manufacture 10 cm3 and 25 cm3 work pieces, achieving precision of 50 µm (equal to the radius of a human hair), and a density of about 99%. Its products made of titanium alloy powder have a tensile strength of 950 Mpa and above, which has reached the level of medical instruments, making it qualified to produce complex-structured golden ornaments, metallic molds, medical instruments, and components.

In recent years, with the 3D metal printing technique, ITRI has assisted the domestic manufacturers in developing LED lighting fixtures, optical lenses, molds of automobile parts, surgical instruments, and surgical guides. ITRI has also collaborated with medical centers to work on bone nails with biomimetic structure, which are now in the stage of animal experiment.
