The paper introduces an innovative aerospace component production approach employing
Wire Arc Additive Manufacturing (WAAM) technology to fabricate near-finished preforms from
Ti6Al4V titanium. Tensile tests on WAAM Ti6Al4V workpieces demonstrated reliable mechanical
properties, albeit with identified anisotropic behavior in horizontal samples, underscoring the need
for optimization. This alternative manufacturing strategy addresses the challenges associated with
machining forged preforms, marked by a high Buy To Fly (BTF) ratio (>10), leading to material
wastage, prolonged machining durations, elevated tool expenses, and heightened waste and energy
consumption. Additionally, logistical and storage costs are increased due to extended delivery
timelines, exacerbated by supply issues related to the current unstable situation. The utilization of
WAAM significantly mitigates initial BTF, preform costs, waste production, machining durations, and
associated expenditures, while notably reducing lead times from months to mere hours. The novelty
in this study lies in the application of Wire Arc Additive Manufacturing (WAAM) technology for the
fabrication of titanium aircraft components. This approach includes a unique height compensation
strategy and the implementation of various deposition strategies, such as single-seam, overlapping,
and oscillating. [--]
