Title:
Influence of spatter generation in SLM processing on the properties of powder material
Abstract:
A major drawback of additive manufacturing is the deposition of spatter into the surrounding powder or the solidified layer during fabrication which diminishes the microstructural and mechanical properties of AM parts. Until now, the phase change, impurity content, and powder size distribution changes resulting from the ejection of spatter powders are not well understood. There is an obvious need to characterize the spatter particles and systematically analyze the location of these fallen spatters. This study focuses on the identification of critical zones that are vulnerable to spatter deposition, which in turn enable the prediction of mechanical properties of the neighboring parts located on the build plate. The characterized powder spatter behaviors, together with the obtained information on the location of these fallen spatter particles, will then be used to aid production planning and optimization towards better print quality and enhanced sustainability performance in AM.
