Embodiments of an additively fabricated turbine blade having an integral tuned mass absorber are disclosed herein. The tuned mass absorber has an elliptical cross-section that results in the suppression of blade vibrations in at least two orthogonal modes of vibration. The tuned mass absorber is formed simultaneously during the additive fabrication of the blade. In an embodiment, the tuned mass absorber extends spanwise. In another embodiment, the tuned mass absorber extends chordwise. The dynamic responses of these spanwise and chordwise tuned mass absorbers are analytically predictable such that the dynamic responses may be incorporated into the design process of the turbine blade.
