Comparison to 3D Printed Sand Molds Both methods use sand held together by a chemical binder. 3D Printing a sand mold is an additive manufacturing method, where the mold is made layer-by- layer. RoboMolding takes a solid block of sand (blank) and carves away at the sand, leaving the desired cavity. Both the Robot and 3D Printer are programmed to 3D Solid Model. Advantages of RoboMolding RoboMolding can be used with a variety of mold media, such as: Silica, Zircon, Chromite, Ceramic including thermally reclaimed sand with sand additives, such as iron oxide to improve finish. RoboMolds are capable of using a flask for handling, allowing shipment to other facilities in sizes up to 80x100” in a more time and cost efficient manner than printed molds and cores. DOUG IMRIE President, SOUTHERN CAST 16 PART BUYERS A U T H R I T Y ROBO-CASTING UNDERSTANDING ADDITIVE MANUFACTURING & APPLIED TECHNOLOGIES RoboCasting is an applied manufacturing process that creates sand molds for metal casting that eliminates the need for a pattern. A robot is programmed to mill the sand to create the mold, then the metal is poured in the sand Robomold.
