Fracture mechanical characterization and lifetime estimation of near-homogeneous components produced by fused filament fabrication
TL;DR: In this paper, the authors investigated different fracture mechanical properties on specimens produced by fused filament fabrication (FFF) under optimized conditions dependent on the strand orientation and found that the 90° orientation outperformed the 0° orientation in certain cases.

Anisotropic material properties of fused deposition modeling ABS
TL;DR: In this article, the properties of FDM parts fabricated by the FDM 1650 were analyzed using a Design of Experiment (DOE) approach, such as raster orientation, air gap, bead width, color and model temperature.
Journal ArticleDOI
Parametric appraisal of mechanical property of fused deposition modelling processed parts
TL;DR: In this paper, five important process parameters such as layer thickness, orientation, raster angle, Raster width and air gap are considered and their influence on three responses such as tensile, flexural and impact strength of test specimen is studied.
Journal ArticleDOI
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.
