ENSA Exclusive Webinar on Direct Energy Deposition

Webinars 07 September 2022

ENSA Exclusive Webinar: A vision of Direct Energy Deposition Arc Additive Manufacture as a Digital Manufacturing Technology of Tomorrow 

Time: 11am, Spain/10am, UK

Arc-based additive manufacturing (AM), also known as Directed Energy Deposition (DED) arc, is gaining significant interest in various industries, eg nuclear power, oil & gas, aerospace, construction and marine, as its high deposition rate renders it promising for large load-bearing structures. TWI's technical expertise includes many decades of theoretical and practical knowledge, experience and capability in the suite of AM processes and supporting technologies such as metallurgy, materials analysis and non-destructive evaluation. In addition, TWI is operating an integrated programme of internally funded research for AM which includes other aspects such as in-process monitoring, modelling and simulation, design for AM, product engineering and digital system integration.

This webinar will examine how some of the research into DED arc AM underway at TWI contributes towards the vision of a digital manufacturing process of tomorrow. This will include some of the complexities of feedstock, processing, monitoring and quality assurance, with examples of work at TWI for energy and other sectors involving similar applications.
