One-piece, integrated vehicle fascia and energy absorbers and methods of forming the same are disclosed. The one-piece vehicle fascia may include a fascia body and an energy absorber integrally formed with the fascia body. The energy absorber may include an open lattice portion including at least one lattice wall extending rearward from a front portion of the fascia body and adjoining at least two open cells. The lattice wall thickness may be smaller at a front portion of the energy absorber than at a rear portion. The open lattice portion may be formed as a honeycomb structure. The one-piece, integrated vehicle fascia and energy absorber may be formed by an additive manufacturing process (e.g., 3D printing). The process may include building the one-piece vehicle fascia in a plurality of successive layers each having a uniform thickness.
