Interfacial bond formation of thermoplastic polymers with deformation histories in additive manufacturing KU Leuven
Polymer-polymer interface is everywhere in 3D printed parts due to the additive manner of manufacturing. Weak interfacial performance often limits functional applications of fused filament fabrication (FFF) printed parts. Although physical processes in FFF are well-known, it has never been noticed that the polymer strands can often be greatly stretched during the deposition to lay down the material. The elongational strain of the stretch can ...
