    Robotic Additive Manufacturing

    Technical Details

    Viridis3Dís Robotic Additive Manufacturing (RAM) system is novel in both its scalability and simplicity. By attaching a printhead to the end of an industrial robotic arm, Viridis is able to print large complex molds and volumes of cores.

    The system works by filling an open tray on the back side of the printhead assembly with sand (solid consumable) from the hopper sand delivery system. The robot positions the printhead over the build table, drops sand, spreads it and prints all in a single pass. When setting up for the next pass, the robot rises in height by the layer thickness to add vertical depth. The process continues until the mold is complete.

    CAD software directs the robot arm with prinhead to lay down thin layers of sand and binder jetting fluid. Curing is quick and backing delivers a strong final product that is ready for casting within hours.
