Universidad de Cádiz 10, E-11519, Puerto Real, Cádiz, SPAIN Abstract Fused Deposition Model is one of the main Additive Manufacturing processes. Nevertheless it has some limiting features. One of them is the surface quality of the product. For this technique, a specimen has been proposed through the modification of two important manufacturing parameters: the feed rate and the extrusion temperature. This allows analyzing the impact of such parameters, both individually and jointly, in the quality of the generated surface. The material selected for this specimen has been Polylactic Acid (PLA). The theoretical surface roughness has been determined as a function of the two studied process parameters. The deduced equations can be used to calculate the quality of the manufactured parts.
