Résumé
Fused deposition modeling is an additive manufacturing process of building up a part layer by layer, with the strength of that part reliant on the bond strength between the fused layers. It is important to select printing parameters that result in a high inter-layer bond to maximize the overall structural integrity of the part. This research aims to explore the variation in the strength in addition to the mean strength in between the layers, which is critical to ensuring a more structurally sound part and should be kept in mind while choosing the printing parameters. This challenges the notion that the printing parameter that would yield the most structurally sound part would be the part with the highest mean bond strength. This research used special test samples to isolate the interlayer bonds for tensile strength testing. The tests were performed on samples with three interlayer bonds and the data was analyzed using Weibull statistics to determine the predicted tensile strength for up to 500 active layers. The tested parameter was nozzle extrusion temperature with a range of +/- 10 oC from the manufacturer’s recommended temperature. The printed polylactic acid (PLA) material had a higher average tensile strength at 205 oC than at 215 oC. However, the samples printed at 215 oC had less variation in bond strength (lower Weibull modulus) and once the number of interlayer bonds in the parts surpassed 106 layers, the samples can be expected to have higher overall tensile strength.
