Development of lattice structure with selective laser melting process: A state of the art on properties, future trends and challenges

Lattice structures are vital for biological applications because of its numerous benefits (for example, faster and stronger binding to bone tissue). Consequently, processing of lattice structure is a particularly popular area of study currently. In this study, additive manufacturing technologies utilized in several engineering disciplines were collated and their merits and shortcomings were examined. Numerous sectors and disciplines view lattice structured additive manufacturing as a prototyping technique. In recent years, additive manufacturing technology has also progressed toward the fabrication of useable final goods. The objective of this review is to classify the produced systems under the headings of aviation, automotive, and military technologies within the context of engineering and to compare them by examining the research and technology firms in this sector. In this categorization, lattice-structured additive manufacturing techniques are categorized as an engineering production technology, and examples of this field are investigated. Technologies, which are examples of diverse engineering applications, are categorized under four primary headings: additive manufacturing knowledge, selective laser melting (SLM), lattice structure, and changeable porosity cellular structures.
