The company adheres to technological innovation as the core driving force, the leading product binder jet (3DP/BJ) 3D printing equipment and services, based on the core technology of binder jet molding, the use of high-speed and high-precision jet control technology, high densities of powder bed spreading technology, combined with self-developed special high-performance binder, which can realize high-quality, high-efficiency, high-precision, automation, batch manufacturing, the technical level of international The technical level is up to the international first-tier level. The company has successively completed the development of binder jet (3DP/BJ) 3D printing equipment such as 3DPTEK-J160R/J400P/J800P, 3DPTEK-J1600Pro/J1600PLus/J1800/J2100/J4000. At the same time, the company has conducted in-depth research in the development of material system formulations, molding process optimization, product performance enhancement, etc., and has successfully researched and launched 5 series of water-based binder and organic solvent binder formulations for more than 20 types of base materials, including iron-based alloys, light metal alloys, ceramics, etc., as well as nearly 30 types of binder jet process formulations, and has the ability to independently design binder formulations, which is able to meet the user's needs. We have the ability to design binder formulations independently, which can satisfy the users' demand for customized binder development for new materials and new applications, and fill the gaps in the field of domestic binder.
