document: Analysis of the surface roughness and dimensional accuracy capability of fused deposition modelling processes Building up materials in layers poses significant challenges from the viewpoint of material science , heat transfer and applied mechanics . However , numerous aspects of the use of these technologies have yet to be studied . One of these aspects is the characterization of the surface roughness and dimensional precision obtainable in layered manufacturing processes . In this paper , a study of roughness parameters obtained through the use of these manufacturing processes was made . Prototype parts were manufactured using FDM techniques and an experimental analysis of the resulting roughness average -LRB- R/sub a / -RRB- and rms roughness -LRB- R/sub q / -RRB- obtained through the use of these manufacturing processes was carried out . Dimensional parameters were also studied in order to determine the capability of the Fused Deposition Modelling process for manufacturing parts
