A Framework to Assess the Impact of Recycled or Reused Metal Powder on Circular Additive Manufacturing

Additive manufacturing (AM), with its design advantages and economic and environmental benefits, facilitates the metal manufacturing industry in overcoming the changing world dynamics Additionally, as access to raw materials has become more challenging in recent years, accompanied by an associated increase in raw material costs, researchers are investigating the effects of recycled or reused metal powder in AM on the particle properties of parts. However, the economic and environmental impacts of these effects on companies have not yet been thoroughly investigated. This study has developed a conceptual framework to delve into the impact of using recycled or reused metal powder on the printing quality and production performance of AM parts from a life cycle perspective.
