Slicing and Contours Generation for Fabricating Heterogeneous Objects

  title={Slicing and Contours Generation for Fabricating Heterogeneous Objects},
  author={Y. K. Siu and S. T. Tan},
A contour sub-division algorithm on each layer arising from slicing a heterogeneous object is proposed. Within each slice, the material grading is decomposed into subcontours according to the different grading variation. A parameter called “grading step-width” is defined to control the number of sub-contours and resolution of the grading. With such discretization, it is, therefore, possible to build a heterogeneous object on layered manufacturing machines of different fabricating precision… CONTINUE READING
