Key Findings

  • 01The 'On-Edge' building orientation exhibited the longest vibrational duration before fracturing across all printing angles.
  • 02An 'On-Edge' orientation with a 15°-75° build angle resulted in the highest fatigue life, averaging 1592 loading cycles.
  • 03In contrast, 'Flat' and 'Upright' orientations with the same 15°-75° build angle had significantly lower fatigue lives (290 and 39 cycles, respectively).

Method & Evidence

AimTo investigate the influence of part-build directions and build orientation angles on the fatigue behavior of ABS components produced via Fused Filament Fabrication (FFF).
MethodEmpirical investigation
ProcedureABS test samples were printed using FFF with a 50% infill density. Samples were oriented in three distinct directions (Upright, On Edge, Flat) and at various build angles ([0°, 90°], [15°, 75°], [30°, 60°], [45°]). The fatigue life (number of loading cycles before fracture) of these samples was then measured under tension-tension cyclic loading.
ContextAdditive Manufacturing (Fused Filament Fabrication) of polymeric materials.

Strengths & Limitations

Strengths

  • +Directly addresses a gap in knowledge regarding FFF-ABS fatigue behavior.
  • +Provides quantitative data on the impact of specific build orientations and angles.

Limitations

The study was conducted in a controlled lab environment and may not fully represent real-world usage conditions. The specific type of ABS and FFF printer used could influence the results.

Reliability & validity

The study's validity is supported by empirical testing of multiple orientations. Reliability could be enhanced by increasing sample sizes for each condition and performing statistical analysis to confirm significance.

Think critically

How might the internal structure (e.g., infill pattern and density) interact with build orientation to further influence fatigue behavior?

Paragraph starter

The fatigue performance of FFF-printed ABS components is significantly influenced by build orientation. Research indicates that an 'On-Edge' orientation, particularly with build angles between 15° and 75°, can yield a fatigue life exceeding 1500 cycles, a substantial improvement over 'Flat' or 'Upright' orientations which fracture much sooner. This highlights the critical need to consider manufacturing orientation during the design phase to ensure component durability in applications involving cyclic stress.
