Method & Evidence

AimTo determine the impact of various post-processing methods on the dimensional accuracy of small plastic parts produced via Selective Laser Sintering (SLS) and Fused Deposition Modelling (FDM).
MethodExperimental comparison
ProcedureTest pieces were manufactured using SLS (Nylon, Alumide®) and FDM (ABS). These parts then underwent various post-processing treatments including tumbling, shot peening, hand finishing, spray painting, CNC machining, and chemical treatment (acetone vapor smoothing for ABS). Dimensional deviations were measured using touch probe scanning and statistically analyzed.
