#### 3.1.4 Most Frequently Cited Documents  
The list of the top 10 articles, ordered according to the number of citations they have received, can be found in Table 9. The number of citations ranged from 332, which corresponded to the least cited article in the ranking, to 1181, which marks the most cited article that ranked first. While a more detailed examination of emerging research areasidentified through frequently selected author keywords will be presented in the subsequent section, an analysis of highly cited publications can provide preliminary insights into the most relevant aspects that have captured the attention of researchers engaged in additive manufacturing research. \begin{table}
