Abstract:
A method for stereolithographic manufacturing of a unitary article comprising a plurality of components, at least two of the components having different densities, said method comprising at least the steps of:producing design data for said article; separating the design data for the article into regions of different densities, these regions forming said at least two components; loading the design data for said at least two components into a software package adapted to slice the design data into thin cross-sectional layers; positioning said at least two components using said software package to overlap and form a substantially complete and accurate representation of said article, slicing said design data for said at least two components into thin cross-sectional layers; and controlling a stereolithographic apparatus in accordance with the design data for each of said cross-sectional layers to produce said unitary article from said plurality of components.
