Abstract
Laser additive manufacturing (LAM) is layer by layer built up a 3-D part using either a bed or stream of powdered material. In this paper, the heat transfer and melt solidification of iron powder in the direct metal laser sintering (DMLS) process with low laser powers have been experimental investigated. The experimental results of various properties of each layer and properties among the multiple layers due to the laser power, the scanner rate, of the frequency of the laser pulse, have been shown and discussed. The process will be improved by numerical modeling in the future.
