6 CONCLUSIONS
Two basic methods to reduce repositioning distances
in the path planning have been presented. The methods
proposed include not only contours in the analysis but
also continuous raster segments (CRS).
The results showed that the gain is considerable
when using optimization in the AM path planning.
According to the geometry, different methods give the
best results. In general it is possible to say that for sim-
ple geometries, few contours and few CRSs, method 1
gives a better result. As the number of contours and the
CRSs increase, method
