N2 - The current study investigates the influence of layer-by-layer shot peening (SP) on the low velocity impact properties of P430 acrylonitrile butadiene styrene (ABS) parts processed by fused filament fabrication (FFF). The experiment examines the relationships between layer peening frequency and build orientation with the impact performance. Preferential layers were shot peened to form cumulative mechanical properties that influenced low strain rate impact behavior. Samples peened every three, four, and five layers were compared to surface-only peened and non-peened samples. Two different printing orientations were examined. Low strain rate impact behavior after hybrid additive manufacturing was assessed by drop tower impact and Charpy impact. Results revealed that layer peening frequency and printing orientation influence ABS' ability to absorb energy and resist fracture. SP between printed layers enhanced the impact strength of ABS. Less frequent peening and side aligned printed parts resulted in a higher toughness, impact strength, and breakage resistance.
