Effect of processing conditions on the bonding quality of FDM polymer filaments
TL;DR: In this article, the authors investigated the mechanisms controlling the bond formation among extruded polymer filaments in the fused deposition modeling (FDM) process and showed that the bonding phenomenon is thermally driven and ultimately determines the integrity and mechanical properties of the resultant prototypes.
