IMProVing directed energy deposition: Industry collaboration overcomes distortion in new DED additive manufacturing processes with simulation

Directed energy deposition (DED) is a powerful additive manufacturing technique that combines a high degree of freedom in design with relatively high deposition rates that can increase throughput. DED structures are created by repeatedly depositing weld beads from powder or wire feedstock, which als...

Description
Summary:Directed energy deposition (DED) is a powerful additive manufacturing technique that combines a high degree of freedom in design with relatively high deposition rates that can increase throughput. DED structures are created by repeatedly depositing weld beads from powder or wire feedstock, which also makes it an attractive technique for hybrid manufacturing because features can be added to a base component. However, the numerous heating and cooling cycles involved in the deposition process result in a complex thermal history that can entail distort the entire component.
