Implication

Experimental study demonstrates over 90% surface roughness reduction in 3D-printed AlSi10Mg components, indicating the efficacy of abrasive flow finishing.

Key Points

To investigate the efficacy of abrasive flow machining (AFM) in reducing surface roughness and eliminating defects in AlSi10Mg alloy parts produced via direct metal laser sintering (DMLS).
Conducted a full factorial experimental design altering abrasive grain size (240 and 400 mesh), abrasive concentration (40% and 60%), and cycle numbers.
Assessed surface performance via surface roughness measurements, material removal rate (MRR), macroscale morphology, and scanning electron microscopy (SEM), alongside numerical optimization.
AFM improved surface quality across all testing conditions, achieving surface roughness reductions exceeding 90% under optimal settings.
Cycle number acted as the dominant parameter influencing roughness evolution and material removal rate, with SEM confirming the progressive removal of melt pool asperities and adhered particles.
The optimal experimental configuration was identified at 400 mesh abrasive size, 60% abrasive concentration, and approximately 20 cycles.
