| Abstract Scope |
Additive manufacturing (AM) layering methodologies allow full freedom to create any desired novel and complex structure. However, AM, particularly FDM parts, lack the consistency and strength needed for functionality due to poor fusion between interfacial layers. This research explores those connecting layers and how thermoplastic interlaminate strength can be maximized through atmospheric plasma exposure. These plasma treatments are capable of efficiently removing the filament’s surface of volatile organic materials and prepping the material for better adhesion to increase the energy and wettability of the surface layer. For analysis, acrylonitrile butadiene styrene filament was treated and then manufactured to create impact testing specimen to observe the absorbed impact energy of the interlaminate layer. Preliminary tests using derived plasma methodologies have shown promising results with an improvement of interfacial bonding. Thus, multiple materials can be treated to minimize delamination with hybrid AM and allow functionality during high impact operations. |
