This study presents a transfer learning-based physics-informed neural network (PINN) model for accurately predicting the 3D temperature field in laser-based directed energy deposition of aluminum-magnesium alloy. The model integrates a lightweight architecture and incorporates physical laws to enhance prediction accuracy, achieving an average temperature prediction error of less than 1.3%. The proposed framework demonstrates significant improvements in computational efficiency and can be adapted for other m
