Metal additive manufacturing (AM) has rapidly become an important research topic, but also an underpinning technology for a range of emergent research fields. From humble beginnings driven by crude machine tools to sophisticated, robotised production systems; metal AM has moved away from a laboratory peculiarity towards an established production technique. So what next?
This talk will explore AM research activity from within my team relating to the key challenge areas in my view (materials, processes and design) which will drive this technology forwards over the next ten years. We will examine the shortfalls in our knowledge and the physical phenomena that must be mastered in order exploit the full potential of these technologies. Through new insight to the processes-material interaction coupled to design and more established technologies there is hidden capability awaiting our attention.
Discussion will conclude with a personal view of the materials and manufacturing challenges that face humanity as developed nations enact ‘net-zero’ manifestos. The role manufacturing technology will play in delivering net zero cannot be overstated as we approach a nexus of excess demand for materials and energy. It is apparent that we are yet to devise the building block technologies that will allow us to thrive under increasingly challenging conditions. We will dedicate some time to consider a vision for manufacturing in 2050 and the level of resilience that will be required to maintain and perhaps enhance our way of life.
