Performance-control-orientated hybrid metal additive manufacturing technologies: state of the art, challenges, and future trends

Abstract

Highlights Performance-control-oriented hybrid additive manufacturing was defined as the review scope. Multifarious technologies were classified, summarized and synthesized based on applied objects. Microstructural evolution, mechanical property, and defect elimination were depicted and compared. The synergetic enhancement of strength and ductility was statistically measured and analyzed. Future development trends were predicted on account of the historical outline and research status.
