Assessing the influence of significative parameters used in 3D Fused Filament Deposition

The present article presents an analysis of the several parameters used at Fused Filament Deposition-FFD 3D printing process. To evaluate these parameters, a laptop / tablet support has been chosen as a subject that presents different characteristics both from the point of view of mechanical demands, to which it is subject, as well as geometry. The reason for choosing such an object to be produced by additive technology is the fact that in its geometry are encountered most of the spatial surfaces that present difficulties to be obtained by this method. In this context, the article highlights the steps that are necessary to get 3D printed objects to meet the initial design requirements. For the assessment of the degree of influence, parameters were identified and then they were evaluated to find an optimal solution. In the conclusions are presented some useful values for practical applications of this type and some considerations about two types of 3D slicers. (paper)
