Abstract
In the present work, the influence of different printing parameters (number of perimeters, flow, extrusion temperature, layer height and printing speed) on the watertightness of 3D printed parts has been studied. The vessels have been printed on polyethylene terephthalate glycol (PETG) by fused filament deposition modeling (FDM). A total of 27 prismatic vessels have been manufactured, following a fractioned experimental design. By means of a simple test, the quantity of water that has leaked from each vessel after seven hours has been measured. After analyzing the results obtained, using Taguchi method and analysis of variance (ANOVA), it can be stated that the number of perimeters and the flow are the most influential parameters in the watertightness of the vessels. One of the vessels tested had zero leakage. With the printing parameters of this vessel, an housing has been printed for an ARDUINO board. The watertightness of the housing has been tested by immersion at a depth of 1 m for 30 min, according to the UNE-EN 60529:2018 standard. Although it did not pass the test, the quantity of water that entered the casing was less than 0.5 g.
