Process control testing for fused filament fabrication [PDF]
Rapid Prototyping Journal, 2017 Purpose The purpose of this research is to determine what tests can be most useful in quality assurance and control when using fused filament fabrication (FFF) 3D printing machines. The quality of the bond between layers is critical for the structural integrity of the fused filament fabricated parts.
