Increasing effort and resources are being put into metal recycling to preserve resources, reduce ecological damage and save energy. This necessitates looking into the possibility of reusing machining waste (chips/swarf) in place of newly refined metal. This paper illustrates the viability of using laser metal deposition as a method for locally recycling machining. A lot of research work on laser metal deposition using different metal powders of up to 150 microns is available, but in this paper carbon steel machining swarf with non-standard particle size and shape is deposited. The feasibility of using this kind of build material is established following analysis of the different outcome parameters including clad geometry, microstructure and physical properties.
