Sustainability metrics for rapid manufacturing of the sand casting moulds: A multi-criteria decision-making algorithm-based approach

Additive Manufacturing has significantly developed over the years and is widely used in most industrial applications. Rapid Tooling refers to manufacturing tools (moulds dies) using techniques. An essential application of 3D printing sand moulds for castings. Metal casting an energy-intensive process; a lot research gone into sustainability assessment traditional In this work, robust decision-making approach implemented mould manufacturing. Sustainability metrics production are formulated, conventional compared against printed moulds. A Multi-Criteria algorithm implemented, effect batch size also studied. The discussed can help decision-makers choose best technique intended number be manufactured.
