Method & Evidence

AimTo investigate the effectiveness of neosanding post-processing in reducing surface roughness of extrusion-based 3D printed PLA parts and to identify the key process factors influencing this improvement.
MethodExperimental comparative analysis
ProcedureThe study involved applying neosanding post-processing to PLA parts fabricated using fused filament fabrication (FFF). Key neosanding parameters (spacing, speed, and flow rate) were varied at four levels each. Surface roughness was measured using both a stylus profilometer and confocal profilometry, quantifying the reduction in the average roughness (Ra) parameter.
