Laser direct metal deposition (LDMD) is a rapidly emerging additive manufacturing technique offering attractive characteristics like high deposition rates, component repair, and deposition of functionally graded materials. Experimental investigations have been carried out to deposit SS 316L structures at higher deposition rates using LDMD. A continuous fiber laser operating at a wavelength of 1070 nm is used to deposit the structures under different processing parameters like power, scanning speed, and powder feed rate. A power range of 600 W to 1200 W is found to be optimal with speed varying in the range between 10 mm/sec and 25 mm/sec. At low power with higher velocities, a low layer thickness is obtained and vice-versa. With an increase in the power and the decrease in the speed, deposition rates are increased. The findings will help to develop pre-processing, online-processing, and post-processing strategies for LDMD.

Abstract


Laser direct metal deposition (LDMD) is a rapidly emerging additive manufacturing technique offering attractive characteristics like high deposition rates, component repair, and deposition of functionally graded materials. Experimental investigations have been carried out to deposit SS 316L structures at higher deposition rates using LDMD. A continuous fiber laser operating at a wavelength of 1070 nm is used to deposit the structures under different processing parameters like power, scanning speed, and powder feed rate. A power range of 600 W to 1200 W is found to be optimal with speed varying in the range between 10 mm/sec and 25 mm/sec. At low power with higher velocities, a low layer thickness is obtained and vice-versa. With an increase in the power and the decrease in the speed, deposition rates are increased. The findings will help to develop pre-processing, online-processing, and post-processing strategies for LDMD.
