Abstract This paper describes a simple variable thickness ruled edged slicing algorithm that produces slices with zero integrated error. In its present state, the algorithm requires pre- sampled data to be taken from the STL file. Data points are extracted in a cylindrical coordinate system giving values of radius at regular intervals delta theta and delta z. Using this data, the algorithm creates slices based on averaging of the data points and the slope of line segments connecting them. Error based constraints are used to determine slice thickness. A three-dimensional visualization technique using color contour plots (representing error) on the surface of the prototyped model provides a means of evaluating the accuracy of the prototyped part.
