The Effect of Atmospheric Pressure Plasma on Inter-Laminar Adhesion Strength of FDM Parts Manufactured with Different Functional Polymers

Abstract

Atmospheric Pressure Plasma (APP) is widely used as a surface treatment method and is capable of increasing the Surface Free Energy of a range of polymers. In this research, the effect of APP treatment on the resulting tensile strength (TS) of functional FDM polymers was analyzed. Multi-material samples of functional polymers were manufactured using mainly polyamide and conductive PLA as objects of study. The interface between those materials were treated with APP in different conditions and the TS data compared.
