Abstract Scope |
Hybrid additive manufacturing brought new opportunities to improve the mechanical properties of materials by secondary processing of individual layers during printing. Previous work demonstrated interlayer shot peening during printing by fused filament fabrication (FFF) affected mechanical behavior while inadvertently imparting debris contamination from pulverized beads. The encouraging results motivated a study on the use of contamination free ultrasonic peening (UP) as an alternative interlayer surface treatment. Ultrasonic peening of FFF printed acrylonitrile Butadiene Styrene (ABS) was studied in order to compare the effects on mechanical properties between ultrasonic peening and previously studied shot peening, different print orientations, and different interlayer peening frequencies. Two different layer peening frequencies (L4 and L8) were compared to an as-printed control (L0). Two orientations for each layer peening frequency were chosen for comparison. Tensile tests were conducted in order to observe the influence of interlayer UP on tensile strength of ABS parts. |
