In recent years, metal additive manufacturing (MAM) has emerged as a promising technique for faster and easier manufacturing of complex parts. One method developed in MAM is additive friction stir deposition (AFSD), which is based on the friction stir welding (FSW) principle. The friction stir principle offers a different manufacturing process compared to fusion-based methods. In AFSD manufacturing, parts are deposited completely according to the solid state principle, without any melting. For this reason, defects such as hot cracking, residual stresses and porosity encountered in other MAM are much less in AFSD. The fact that the feed material used in the AFSD method can be in powder or rod form provides an advantage compared to other manufacturing processes. AFSD has become a promising manufacturing process in sectors such as automotive, maritime and aviation due to its superior features. In this study, the basics of the AFSD method, the studies and results of this manufacturing method for different materials are discussed. The aim of this study is to summarize the developments in the application of the AFSD method to different materials in recent years. It is anticipated that AFSD additive manufacturing will make its name known more in the near future and this review article will lead to subsequent studies.
