Abstract

The selective laser sintering process utilises a galvanometer scanning system to execute vector scanning. By employing a polygon scanning system, it is possible to potentially reduce both
scanning time and cost. This paper details research undertaken to mathematically characterise the time taken to execute vectors of the same length by both raster and vector scanning at a range of
lengths. This is then used to calculate a fill factor to assess what percentage area in-fill is required for raster scanning to be more time efficient. Real data is subsequently used to calculate the fill
factor for increasing values of power at different vector lengths. The inference of this paper is that raster scanning can be more efficient at a fill factor of 80.4% in an average case.
