What is one of the main challenges associated with the use of metal additive manufacturing?

One of the main challenges associated with the use of metal additive manufacturing is high energy consumption during production. Metal additive manufacturing processes, such as selective laser melting (SLM) or electron beam melting (EBM), utilize high-powered lasers or electron beams to melt and fuse metal powders. This requires significant energy input to maintain the necessary temperatures and conditions for effective layering and bonding of the materials.

The equipment involved in these processes, as well as the requirement for a controlled atmosphere to prevent oxidation or contamination, adds to the overall energy demands. This challenge not only affects the operational costs but can also have implications for sustainability, making energy efficiency a crucial consideration in the ongoing development and adoption of metal additive manufacturing technologies.

While other factors such as limited material options, production speed, and precision are also important considerations in the field, they do not universally capture the significant challenge posed by energy consumption in the way that it influences both economic and environmental aspects of metal additive manufacturing processes.
