 note = {The consolidation characteristics of ferrous based powder for Selective Laser Sintering (SLS) and Selective Laser Melting (SLM) are described. Yb : fiber laser beam is applied to obtained the high quality layered structure. In order to investigate the influence of laser conditions on consolidation quality of the layered structure, the maximum temperature at irradiation area of a laser beam is measured with a two-color pyrometer. In addition, the cross section of layered structure and the specific cutting force with dynamometer is evaluated for the optimization of the quality of consolidated structure. The result shows that the consolidated structure was changed with the energy density and the time interval of the laser beam scan. The maximum temperature during laser irradiation was not influenced by the previous laser beam scan when the time interval between the laser beam scan is over 50ms. The pore on the consolidated structure decreased with the increase of energy density, however superfluous supply of energy density caused the precipitation of carbon from the ferrous powder. The specific cutting force of the consolidated structure was greatly related to the ratio of consolidation.},
