“…Jackson et al proposed a local composition control (LCC) approach to represent heterogeneous object in which a mesh model is divided into tetrahedrons and different material compositions are evaluated on the nodes of the tetrahedrons by using Bernstein polynomials [3,4]. Chiu [5] developed material tree structure to store different compositions of an object. The material tree was then added to a data file to construct a modified format being suitable for RP manufacturing.…”

Slicing contour generation for geometric model is a vital process in rapid prototyping manufacturing. When slicing a heterogeneous object (HO), we take into account not only the geometric slicing but also the gradient material information. In this paper, we develop a new method to slice a heterogeneous object where the geometric contours are taken as constraints to resample the heterogeneous information through pixel overlap interpolation and tri-linear interpolation, which can maintain the original heterogeneous material information as much as possible and the slicing boundary as accurate as possible. The novelty of our method is that the gradient material resampling with geometry constraint can guarantee the crisp boundary of the HO slices when the gradient information is converted for geometric space to image space. Experimental results validate that our method can create heterogeneous object slices with more accurate boundary than simple interpolation scheme.
