Generate an adaptive de-cubing automatic processing for laminated object manufacturing (LOM)

A de-cubing process are important in the Laminated Object Manufacturing (LOM) technique, creates a physical model directly from 3D CAD model without mold and dies by using laminated material. The de-cubing process is to assign shape of waste material into generally small square shape that can be easily remove in order to reduce time and avoid prototype damages. The adaptive de-cubing process applies proportion of number of black pixels on considering area per number of total pixels on considering area. If the proportion is more than a threshold, then the considering axis is divided. On the other hade, if the proportion is less than the threshold, then the considering axis is skipped. The adaptive process algorithm has been developed base on MATLAB platform. The result shown that the bigest threshold exploded the rough de-cubing and stair layer contour, while the smaller threshold produced the fine de-cubing and smooth layer contour.
