Description-Optimization of model volume can go a long way in enhancing the quantitative effectiveness of any layered manufacturing (LM) process. This work exhaustively evaluates the effect of contour width, raster width, raster angle, slice height, orientation and air gap on the model volume requirements for basic constructive solid geometry (CSG) primitives. Models have been derived and evaluated analytically and graphically using response surface methodology (RSM) technique to deduce the effect of aforementioned parameters on the model volume estimation for a Fortus 250mc modeler. This work establishes basic design principles for model volume estimation in a given build volume as well as evaluation of different spatial requirements for model volume optimization for Fortus 250 mc modeler in particular and FDM process in general.
