It is well known that the mechanical performance and dimensional accuracy of parts produced by fused filament fabrication are directly related to the printing conditions and to the rheological phenomena inherent to the process, specifically the bonding between adjacent extruded paths/raster. The printing parameters have an important role on the parts performance since they affect the viscosity of the printed material and the temperature at which the consecutively deposited raster are bonded. In this study, the influence of some of the dominant printing parameters, namely the envelope temperature, the extrusion temperature, the use of forced cooling and the extrusion rate, on the parts mechanical performance and dimensional accuracy, is carried out with an ABS filament. Parts performance is evaluated by printing a set of test specimens that are morphologically characterized and mechanically tested. At the morphological level, the external dimensions and the voids content of the printed specimens are evaluated. The bonding quality between adjacent extruded paths is assessed through the mechanical performance of the specimens subjected to tensile loads. In this case, the specimens were all printed with a raster oriented at 90º relative to the tensile axis, in order to highlight the effect of the different printing conditions used. The best performance, resulting from a compromise between surface quality, dimensional accuracy and mechanical performance, was achieved with a heated printing environment and with no use of forced cooling. In addition, for all the conditions tested, the highest dimensional accuracy was achieved in dimensions defined in the printing plane. This work provides a relevant result as the majority of the current printers comes without enclosure or misses the heating and temperature control systems of the envelope, which proved to be one of the most influential process parameter.
