Metal Binder Jetting technology goes back to a development at MIT which originally focused on sand casting forms. Since then, EXONE developed the first metal process based on binder jetting technology followed by DIGITAL METAL. DESKTOP METAL and HEWLETT PACKARD are among the latest suppliers that introduced Binder Jetting systems to the market. The technology principle is still based on the original MIT patents which refer to a powder bed of sand or metal powder on which a fluid binder is locally applied by a nozzle array similar to 2D inkjet printing technology. This fluid binder solidifies by applying heat. After printing, the powder cake is being removed from the system and placed in a curing furnace. Depending on the binder, the curing temperature is between 100-200°C and takes around 24 h.
