| Summary, etc. | During 3D printing part, many process parameters of the printer are required to be<br/>considered that affect the mechanical properties such as part strength. This research investigates<br/>the influence of layer height and print speed variations on the strength and quality of Fused<br/>Deposition Modelling (FDM) parts. The article shows the realized results of experiments and<br/>measurements of mechanical strengths, artifact dimensional accuracy, surface roughness and hatch<br/>distances. Proper selection of printing parameters is essential for achieving desired mechanical<br/>properties in 3D printed parts. The study employs Design of Experiments (DOEs) on different<br/>shaped geometries by using full factorial methodology to select the significant parameters for<br/>further research. A comprehensive test artifact is used to assess printer performance and<br/>dimensional limits. The test artifact, designed with various combinations of print speed and layer<br/>height, is subjected to 3D scanning to create 3D deviation maps, perform 3D comparisons, and<br/>calculate percentage error. Tensile tests and 3-point bend tests were conducted on test specimens,<br/>employing combinations of three distinct layer heights and print speeds. These tests were carried<br/>out following ASTM standards D 638 and D 790 to evaluate the tensile and flexure strengths,<br/>respectively. The outcomes indicate that extra fine layer heights and the lower print speeds yield<br/>higher strength and dimensional accuracy. Surface roughness and hatch distance analyses exhibit<br/>consistent patterns across both the tensile and 3-point bend tests. The results contribute to the<br/>exploration of FDM parameters for specific applications and the progress of additive<br/>manufacturing methodologies.<br/> |
