Recent trends and research opportunities in hybrid additive manufacturing

Over the past few decades, manufacturing and production have undergone rapid development, particularly through the combination of additive manufacturing (AM) and other digitally driven manufacturing machines, creating hybrid additive manufacturing (hybrid-AM). However, despite significant growth, hybrid-AM has not yet gained acceptance at an industrial level due to certain limitations. This article aims to provide the latest information and discuss recent research trends, opportunities, challenges, and indicators in the field of hybrid-AM. Specifically, it will review and analyze literature related to the development of hybrid additives and subtractive processes known as HASPs, and identify future research avenues. Additionally, the article will identify key traits and research work in HASP systems, as well as present the future of HASPs and other types of hybrid machine tools based on recent trends.
