The influence of printing parameters, including layer thickness, infill density, printing speed, and nozzle temperature on the mechanical properties, is studied, and the design of the experiment (DOE) is made through Taguchi L 9 orthogonal array. The specimens for the tensile test are fabricated by the material extrusion (MEX) 3D printer, which is also known as fused deposition modeling (FDM) or fused filament fabrication (FFF). After conducting the tensile test, this research considers four significant outcomes: tensile strength, maximum load, elastic modulus, and elongation at break. Further analysis of the obtained results from mechanical testing is performed through analysis of variance (ANOVA) to determine the significance of each parameter on the mechanical properties. Moreover, prediction and optimization are conducted to verify the obtained results from the DOE. Furthermore, scanning electronic microscopy (SEM) is used to analyze the fracture zones, cracks, voids, and fiber/matrix adhesion of the FDM fabricated parts which demonstrates that the lower layer thickness provides better adhesion and fewer voids between successive layers and thus exhibits better mechanical performance.

However, parts produced by material extrusion have relatively poor mechanical performance, dimensional accuracy and thermal performance as compared to parts produced by subtractive manufacturing due to high void content. Previous studies have suggested print path deviation as the cause of these voids, but no attempt has yet been made to characterise these deviations. In this study, we propose a method to assess print path deviation for material extrusion that may reduce the formation of voids in printed parts. Geometric features including straight paths, various angled corners and curves of varying radii are printed at different print speeds using an open-source printer and then imaged under a microscopic. The deviation in print path centroid and width is classified as being a combination of systematic and stochastic deviations. Systematic deviation is determined by the difference between the mean of the actual print path and the ideal print path sent to the printer by the user. Stochastic deviation represents the randomness across print samples and is given by the root mean square deviation. The relationship between stochastic deviation between any two points along the print path is determined by a correlation coefficient. The results show that both print speed and different geometric print features affect the amount of deviation in the print path. In the case of correlation of the stochastic deviation along print paths, geometric features are found to have a much greater effect than print speed. The proposed method provides a low cost and highly transferrable technique to characterise the print path deviation within material extrusion parts with respect to varying printing parameters. An accurate understanding of local print deviations within a part plays a major role in the analysis and topology optimisation of 3D printed parts and gives the ability to assess the print quality and identify the root cause of print deviations, thus reducing voids and improving mechanical performance, dimensional accuracy and thermal properties of the printed part.","PeriodicalId":36643,"journal":{"name":"Progress in Additive Manufacturing","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136192240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
