Abstract:Sintering mechanism of the single-component/multi-component metal powders and the pre-alloyed powders during Direct Metal Laser Sintering (DMLS) process were analyzed. The material properties such as surface tension, viscosity, particle size and its distribution, and absorbance/ reflectivity together with the processing variables such as laser parameters, layering thickness of powders, atmospheric control, bed pre-heating temperature, and sintering assisted material, which affect sintering and densification of DMLS-processed parts, were discussed. The further directions of the research method in DMLS were addressed.
