Popis:	Manufacturing industry is moving toward a process model involving rapid and frequent product deliveries to increase their consumer base. Employing laser sintering methods in product fabrication provides a superior quality, low cost and high-fidelity solution to support this. Effective monitoring and diagnostics of laser sintering process become a critical task in this regard. This paper focuses on analyzing spatters and plume generated during continuous laser sintering for fabrication of circular rings. Analysis using high-speed photography and subsequent image processing was undertaken. By varying laser parameters, the generated spatter and plume was tracked and features such as spatter count, spatter size, and plume area were examined. Results show that spatter count and plume size are related to the variations in laser power intensity. Optimal power settings are shown to produce best quality product. The proposed analysis method could be used to monitor the stability of laser sintering process.
