On the basis of years of 3D printing 1.0 equipment and applications, we have independently mastered 3DP and BJ line scanning high-speed 3D printing 2.0 equipment, materials and processes, which can meet the manufacturing needs of products of different sizes (from millimeter to meter), and independently researched and developed a series of intelligent equipment, such as SLS selective laser sintering, SLM selective laser melting, 3DP sand printing, BJ binder jet metal/ceramic printing and so on.
