Additive manufacturing has changed the way products are designed, manufactured and distributed to the consumers. It has made possible to create products previously thought too complex. Aerospace, medical, automotive and energy sectors started using additive manufacturing as they realised its potential innovation, financial and efficiency benefits. Despite the progress, there are still challenges that must be addressed, including improving the throughput, Accuracy and repeatability, surface roughness, mechanical properties, establishing standards and protocols, modelling and simulation to reduce the residual stress, certification and reducing the raw material cost. This article gives insights into the present barriers hindering the widespread adoption and research opportunities in metal additive manufacturing.

Abstract


Additive manufacturing has changed the way products are designed, manufactured and distributed to the consumers. It has made possible to create products previously thought too complex. Aerospace, medical, automotive and energy sectors started using additive manufacturing as they realised its potential innovation, financial and efficiency benefits. Despite the progress, there are still challenges that must be addressed, including improving the throughput, Accuracy and repeatability, surface roughness, mechanical properties, establishing standards and protocols, modelling and simulation to reduce the residual stress, certification and reducing the raw material cost. This article gives insights into the present barriers hindering the widespread adoption and research opportunities in metal additive manufacturing.
