Identification and Mapping of Manufacturability Constraints for Extrusion-Based Additive Manufacturing
TL;DR: A set of design-focused manufacturability constraints for the fused deposition modeling/fused filament fabrication (FDM/FFF) process are developed and demonstrated, which will better inform designers considering using FDM/ FFF as a manufacturing process, and help guide design decisions.

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.
