Abstract Scope |
Wire Arc Additive Manufacturing (WAAM) produces large, metallic, near-net-shape components depositing a wire using an electric arc. It has shown great potential in terms of cost savings, material wastage reduction, lead time compression, and supply chain simplification.
This work will compare the environmental impact of several competing manufacturing routes (subtractive, together with a few WAAM variants) for the production of components in aluminium, steel and titanium of interest to the aerospace and energy industries. The comparison is carried out in a product life cycle perspective estimating the embodied energy and carbon dioxide equivalent emissions from the primary production of raw materials until the shipment of the finished product to the customer (i.e. a “cradle-to-gate” approach). Repair cases will also be discussed.
In most cases WAAM is shown to substantially improve the environmental impact of like-for-like components. |
