Abstract Scope |
Many studies have been conducted to better understand the relationship between additive manufacturing process parameters and the resulting structure and properties of manufactured parts.
In this study, Single-track experiments and modeling are conducted, with the aim to investigate the influence of process parameters such as laser dwell time in mitigating pore formation during selective laser melting of SS316L-WC composites.
Results show that the filling of the pores between ceramic particles by the molten SS316L is dependent on the laser dwell time, which in turn, depends on the volume fraction of ceramic reinforcement and initial pore sizes between inclusions. Our experiments, in agreement with our model analysis, with special consideration of inertia effects, show that with the information of the materials property of the matrix phase in a composite system, the printing parameters can be chosen to yield the appropriate dwell time for pore free composites. |
