This paper looks into several ways to increase the energy efficiency of additive manufacturing (AM), with a particular emphasis on metal-based processes like selective laser melting and direct metal laser sintering (DMLS) (SLM). These AM techniques use a lot of energy even when they reduce material waste. The review assesses the efficacy of initiatives in three domains: process optimization, adoption of energy-efficient technologies, and integration of renewable energy. To minimize energy consumption without sacrificing production quality, the study emphasizes the significance of optimizing factors like layer thickness and construction orientation, making use of cutting-edge laser systems, and integrating intelligent monitoring technologies. To lessen the overall energy footprint of AM facilities, the study also examines renewable energy sources including solar and wind power. The study provides a thorough assessment of current strategies and their scalability through a systematic review of the literature from 2013 to 2023. It suggests that a multifaceted approach combining these methods could significantly reduce energy usage in AM while maintaining competitiveness and aligning with global sustainability goals.
