摘要： Additive manufacturing (AM) is one of the emerging manufacturing techniques of immense engineering and scientific importance and is regarded as the technique of the future. AM can fabricate any kind of material, including metals, polymers, ceramics, composites, etc. Selective laser melting (SLM), also known as the laser-based powder bed fusion process (LPBF), is the most widely used AM techniques that can fabricate a wide variety of materials, including Al-based, Fe-based, Ti-based, Co-based, Cu-based and Ni-based alloys, etc. Similar to any AM processes, the SLM/LPBF process also offers several advantages, like added functionality, near-net-shape fabrication with minimal or no post-processing, shorter lead-time, offer intricacy for free, etc. The SLM process has its applications in the aerospace, automobile, oil refinery, marine, construction, food and jewelry industries, etc. However, there exist some shortcomings in the SLM field, which are (a) SLM-based alloy development, (b) the premature failure of materials, even though improved properties are observed, (c) process innovation and development, (d) structure-property correlation and (e) numerical simulations, etc.
