Abstract Scope |
This research aims to investigate the effect of power, inclination angle and the number of laser passes upon dimensional deviation, distortion and porosity of Thin Wall Structures (TWS) made by LB-PBF. Investigating the mentioned parameters is useful to determine the capability of LB-PBF to produce Al-Si-10Mg TWS as well as the manufacturability of these structures. To identify the effect of inclination angle, number of laser passes and laser power on dimensional deviation, distortion and porosity a full factorial Design of Experiments (DOE) has been selected. To discuss the results statistical analyses and simulation of LB-PBF are implemented. Simulations have been carried out using computational fluid dynamic software (Flow-3D V12) and the depth and width of the meltpool are predicted. The obtained dimensions of the melt-track are then generalised based on the thickness of the TWS to confirm the accuracy of the simulation. |
