Abstract A software tool is described that will aid the user in choosing the optimum build orientation to obtain the best composite set of surface finishes on a part built on a Fused Deposition Modeling (FDM) rapid prototyping machine. Experiments were conducted to obtain statistical surface roughness values as a function of orientation and layer thickness. Three types of surfaces (features) have been considered: planar (both upward facing and downward facing (overhang surfaces), quadric and freeform surfaces. Data analysis of surface roughness of planar surfaces at various orientations and their mapping to quadric and freeform surfaces are presented. The decision support software tool allows dynamic color-coded visualization of the surface quality simultaneous with build parameters including orientation and layer thickness.
