Founded in 2008 and based in Shanghai’s Zhangjiang Hi-Tech Park, Shanghai Rongyue Electronics Technology (trading as Royal Electronics, royal3dp.com) built its expertise over 15 years in industrial inkjet digital printing control systems before applying that technology specifically to binder jetting 3D printing. The company supplies a complete 3D-BJ solution stack, print heads, printer control boards, slicing software, and auxiliary function modules, alongside its own 3D-BJ printers, covering sand mold 3D printing, metal 3D printing, ceramic 3D printing, wax model printing, and full-color resin printing. It positions itself around core inkjet printing technology development rather than a single finished-machine product line, supplying components and full systems to other manufacturers and end users across these binder jetting applications.
