The Energy Density as a Reliable Parameter for Characterization of Selective Laser Melting of Various Alloys

Abstract:

Various "energy density" parameters are used very often for comparison of fabrication modes for Selective Laser Melting (SLM) technology. Each SLM mode is determined by a number of process parameters. In this paper the energy density was considered critically as a reliable parameter for characterization of Selective Laser Melting of four various alloys on one SLM machine, on the example of fabrication of cubic specimen. The results obtained show that the energy density can be used for approximate comparison of SLM modes.
