Abstract


In Fused Filament Fabrication (FFF), the perimeter toolpath strategy strongly influences dimensional accuracy of the resulting components. The Arachne algorithm varies extrusion width along each perimeter through a medial-axis beading strategy, adapting to local wall geometry, whereas the Classic algorithm holds the contour width fixed. We compared the two algorithms experimentally on a purpose-designed L-benchmark with wall thicknesses varying from 1 to 5 mm, printed at three nozzle diameters (0.4, 0.6, and 0.8 mm) on a Bambu Lab A1 in PolyTerra PLA. Across 270 micrometer measurements, Arachne reduced mean absolute error by 2.3 to 7.0 times and maintained 100% of features within ±0.1 mm of nominal across all nozzle sizes, while Classic achieved only 78% (0.6 mm) and 89% (0.8 mm). Print-time and material-consumption differences stayed below 1.2% and 1.8%, respectively, confirming negligible production cost.
