Abstract Details

2020, Doctor of Philosophy, University of Akron, Polymer Engineering.
In relation to traditional polymer processing techniques, 3D printing is still being established as a highly useful processing method. As the literature on 3D printing rapidly grows, public users, private companies and researchers alike are constantly learning how to improve on 3D printing methods, procedures and materials. Currently, two of the main deficiencies, which if improved, would greatly benefit fused deposition modeling (FDM) 3D printing are the print quality and mechanical properties of the objects printed. While optimization of printing parameters can facilitate some improvement of these deficiencies, objects printed via FDM printing lack the level of quality and the mechanical strength found in objects made through traditional and well - established processing methods, such as injection molding. In this work, two methods are employed to improve on part quality and mechanical properties. The first method is the use of a novel filament system which aids in filling random air gaps within objects that are FDM printed. This leads to an overall improvement of part quality as porosity decreases while the properties of the objects printed using this filament system are shown to be consistent across multiple printing conditions. The second method is the use of a structure within the FDM printed objects in order to improve impact resistance. Cellular solid structures within literature are shown to be lightweight yet mechanically strong, and therefore quite useful in a variety of applications. Printing of cellular solid structures into 3D objects greatly expands the ever - growing applications of FDM printing. Furthermore, this strategy is promising for 3D printing specifically, due to the ability to easily customize object design with rapidity. Lastly, the catalogue of materials printable via 3D printing is also consistently expanding. While network forming polymers that can be water swollen, hydrogels, have been printed in their hydrated state through inkjet printing, as of yet such materials have not been printed in their dry state. Further materials such as interpolymer complexes have not been studied for processing capabilities using 3D printing. Both of these types of materials are studied in this work for their printability through various 3D printing methods.
