Circular Economy Concept In Additive Manufacturing
Abstract
Recently, there has been increasing concern about thesustainability of the manufacturing industry, one of themajor consumers of energy and raw materials, andtherefore, a major producer of greenhouse gas emissionsand waste. Additive manufacturing (AM) inherentlygenerates less waste than the conventional manufacturing.In this study, the goal was to apply the concept ofcircular economy into AM, by recovering processsidestreams back to the feedstock material for SelectiveLaser Melting. The objective was to prepare powder from100 % scrap feedstock following two routes: 1) mechanicalmilling of agglomerated residue powder, and 2) gasatomization of solid scrap without extra alloying tocompensate possible alloy losses. The powder propertieswere analysed and test specimens for the determination ofmechanical properties were made from the prepared powdersand commercial reference powder. Conducted test seriesshow that with recycled powders properties fullycomparable to reference can be achieved.
