  abstract =     "The significant amount of research has been done in
                 improving the mechanical properties (compressive
                 strength), dimensional accuracy (length, height and
                 width), and build time of the components manufactured
                 from the additive manufacturing process. In contrast to
                 this, the research in the optimization of environmental
                 characteristic i.e. energy consumption for the additive
                 manufacturing processes such as selective laser
                 sintering (SLS), and selective laser melting (SLM)
                 needs significant attention. These processes intakes
                 the significant portion of input laser energy for
                 driving the laser system, heating system and other
                 machine components. With world moving towards
                 globalization of additive manufacturing processes, the
                 optimization of laser energy consumption thus become a
                 necessity from productivity and as well as an
                 environmental perspective. Therefore, the present work
                 performs the empirical investigation by proposing the
                 optimization framework in modelling of laser energy
                 consumption of the SLS process. The experimental
                 procedure involves the computation of energy
                 consumption by measuring the total area of sintering.
                 The optimization framework when applied on the
                 experimental data generates the functional expression
                 for laser energy consumption which suggests that the
                 slice thickness is a vital parameter in optimizing it.
                 The implications arising from the study is discussed.",
