This dissertation focuses on understanding how the interfacial segregation of low molecular weight polymeric species in a polymer blend impacts the interlayer adhesion and mechanical isotropy of objects prepared by fused deposition modeling (FDM), a widely used additive manufacturing technique. The molecular weight, architecture, and chemical identity of the low molecular weight polymer in the blend dramatically impacts the formation of a robust interlayer interface. Additional modification of the low molecular weight component presents opportunities for reactive processing. The impact of covalent bonds between interfacial layers on the interlayer adhesion and overall isotropy of an FDM printed object is examined.
