Abstract In any rapid prototyping process, layer by layer building process introduces an error in the amount of material used compared to the volume specified by the computer-aided design model. This affects the dimensional accuracy as well as the surface finish for different part build orientations. This paper describes a methodology for computing the volumetric error for any orientation of the parts built by the fused deposition modelling rapid prototyping system. The technique can be applied to determine the best orientation of the part, based on the minimum volumetric error. The technique is verified by comparing the results with the experimental measurements of the volumetric errors of the parts built at different orientations. (Auth abstract) [References: 10] XX
