Summary
Additive Manufacturing (AM) or 3D printing as recognised by the public, has grown substantially over the last 25 years into a predicted global business of over $50 billion US by 2026. This growth has focused mainly on small intricate and complex components typically up to 250 mm x 250 mm x 250 mm. Today AM is showing enormous potential to produce metal parts of over 1m in size. New machine designs and processes are being developed, which enable such large parts to be produced much more quickly and efficiently than using traditional forging or casting processes. This presentation will provide an overview of these new machines using powder bed processes, and outline the AM Wire-Arc Direct Energy Deposition process to produce large metallic components.
