    Abstract: Laser wire filling additive manufacturing technology is gradually being widely used in industrial production due to its ability to produce structural components with complex structures, high dimensional accuracy, and good comprehensive performance. However, traditional processing and manufacturing techniques for titanium alloys suffer from high costs, low material utilization, and low efficiency. Therefore, exploration of performance and window of laser wire filling additive manufacturing process for titanium alloy materials has great research significance. In recent years, domestic and foreign researchers have conducted in-depth exploration in this area and made significant progress. This article focuses on basic principles and classification of laser wire filling deposition technology for titanium alloy, and summarizes factors affecting forming and changes in microstructure and properties of titanium alloy in laser wire filling additive manufacturing process with a large number of references. It also analyzes future development trends and main research directions of this technology.
