In 2018, Guangdong Yiner Technology Co., Ltd. made a major breakthrough in the powder making process, and the special powder making equipment for refractory metals developed was successfully put into use, realizing the industrialized production of micron and nano powders for high melting point metals, making up for the blank of supplying domestically-made spherical powders for high melting point metals, which attracted a great deal of attention in the market; on the basis of which Guangdong Yiner tested and validated the refractory metal 3D printing On this basis, GD Yiner has tested and verified the process of refractory metal 3D printing, and confirmed the printing process and technical parameters of spherical tungsten powder on a domestic metal printing equipment.

Tungsten (W) has a broad application prospect in the field of metal 3D printing. As a rare, high-melting-point metal with high corrosion resistance, it is an ideal material for the electronics, electric lighting, chemical processing, aerospace and weapons industries. Smit R?ntgen, a manufacturer of medical imaging components, has developed a process for processing pure tungsten through metal 3D printing for high-precision components used in X-ray fluoroscopy equipment such as CT/PET/SPECT, further increasing the industry's added value.

"GD Yinner's new powdering technology is able to break through the limitations of traditional powdering technology to efficiently prepare high melting point metal powders such as tungsten, molybdenum, and tantalum, and at the same time, ensure that the finished product has a very high degree of sphericity and low oxygen content, which is impossible to achieve with the general preparation methods. This spherical powder has excellent fluidity and filling properties, and can be adapted to the requirements of metal 3D printing." According to Yang Chihong, president of Yinnar, "In addition to the micron-sized powder used in 3D printing, Yinnar has introduced several particle size specifications such as nano and sub-micron to provide customized services for other high-end applications, Yinnar continues to accumulate application experience, focus on the high-end market, and help downstream customers to develop new cutting-edge products."
