SFF also referred to layered manufacturing (LM) which builds up 3Dobjects by successive 2D layer deposition after exporting it as an STL file format fromits CAD environment.This paper aims at overcoming the approximation problem of 2D layer contour fromsliced STL model. The author used a Lagrange interpolation method to increase thepoint’s coordinates of the sliced layer contour in order to reconstruct an accurate andnear net contour of the original sliced CAD model. This method reduced the errorbetween the original sliced CAD model and the actual reconstructed layer contours to0.006%.
