We had developed an adaptive slicing method using the finest layer stacking.
The STL model was sliced with the minimum slice thickness 0.0005in using
ModelWork. Then, a program was developed to analyze the profile variation
from the BIN file. If the profile variation of the adjacent layers is within
the acceptable tolerance, these two adjacent layers are stacked as a single
layer. This examination procedure continues until the profile variation is
out of the acceptable tolerance. Of course, there may are two, three, or
four, or even ten layers are stacked as a single layer. If ten layers are
stacked together, the processing parameters of this 10 stacked layer is the
same as the single layer at 0.005in. The HPGL printing paths of the other 9
layers are removed from the original Bin file. Hence, the determination of
the adaptive slicing layer thickness can be automated and optimized.
However, the processing parameters is still manually determined by the
operator in the variable layer thickness configuration because of interface
problem.
