Challenges and issues in manufacturing of components using polymer-based selective laser sintering (SLS): a review

Selective Laser Sintering (SLS) is a highly promising method that plays a crucial role in advancing the development of high-performance and intricate structural materials. Polymer powders are widely recognized for their exceptional strength and versatility as a lightweight structural material. Significant improvements in processing parameters have also expanded the use of SLS polymer parts for structural applications. This research paper thoroughly analyzes the challenges and issues related to SLS from various perspectives. I have a deep understanding of SLS parameters, metallurgical processes, microstructure evolution, metallurgical defects, mechanical properties, and surface roughness. The goal is to create a foundation of knowledge for future research efforts focused on improving productivity in SLS. In addition, the conclusion emphasizes the challenges encountered in research and the possible avenues for future advancements in SLS polymer parts.
