There are several 3D printing technologies; however, the extrusion-based technology such as fused deposition modeling (FDM) is the widely used one owing to its low cost. The FDM method can be used to fabricate parts with different fill densities, fill patterns, and process parameters such as extruder temperature and print speed. In this research, influence of process parameters such as extruder temperature and speed on the physical characteristics such as the shape and the size of printed fibers in each layer, the fiber distance, and the fiber-to-fiber interface are investigated. In addition, their effects on mechanical characteristics of the printed samples are examined and interpreted with respect to the layer physical characteristics. To accomplish this, phononic metastructure specimens are fabricated using acrylonitrile butadiene styrene (ABS) polymer on a Maker Bot 2X Replicator 3D printer. Three different extrusion temperatures (210o, 230o, and 250o C) and print speeds (100 mm/s, 125 mm/s, 150 mm/s) are considered with an infill density of 50%. Optical microscopy is performed for layer physical characterization while the compression and hardness tests are done to evaluate the mechanical properties such as the hardness, failure strength, yield strength and compressive modulus. It is observed that the print head speed has minimal effect on mechanical properties; however, an improvement in mechanical properties are observed at higher temperature. Also, the lower temperature results in more uniform features within the layers as compared to those printed at higher extruder temperature. 2018 English text Wright State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=wright1547231646016662 http://rave.ohiolink.edu/etdc/view?acc_num=wright1547231646016662 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
