## 5 Conclusions  
This study is the first to examine the effect of deposition pass overlap width on AFSD builds made from a high strength aluminum alloy. This work further assesses the viability of AFSD for a wide range of applications, proving that it can maintain as-deposited material properties over larger builds compared to single-track depositions. The following can be concluded:  
1. AFSD builds with sufficient overlapping deposition paths will produce components with material properties that are comparable to single-row AFSD deposits of high-strength AA7075 in the as-deposited condition.
2. Less than 25% of the deposition width of the overlap may not be sufficient to achieve proper metallurgical bonding and material mixing between separate passes, and thus risks the formation of voids and cracks within the interface boundary.
3. Increasing the amount of overlapping material enhances ductility within the material. A small amount of overlap, or even a gap, will create inconsistent material properties due to non-uniform bonding.  
For future work, supplemental experiments could be performed to evaluate the effect of overlapping deposition passes by focusing on knowledge gaps that were not addressed in this study. One point of interest would be quantifying the tensile behavior for specimens made with an overlap width larger than 38% of the deposition width, which is equal to 9.5 mm in this experiment. These specimens would have to be taken from a wider build made with multiple overlapping regions in order to accommodate the specimen size, while ensuring that the gage section of the tensile specimen is still composed of overlappingmaterial. An additional study could examine the vertical build direction properties of material within the overlap region by producing taller builds composed of several more layers of deposited material.
