JOME Engineering used wire arc additive manufacturing (WAAM) in Dubai to rebuild a 26 kg stainless steel marine propeller directly from 3D scan data of the original part, then reinstalled it on the vessel. The propeller was printed on the Vipra AM system from Italian large-format additive manufacturing company Caracol, which says it is the first 3D-printed marine propeller in the UAE. According to Caracol, printing the propeller cut lead time by about 60% and cost by about 40% compared with casting. The customer had no drawings; the blade curvature, pitch, and blade-to-hub transition details existed only in the physical part. JOME first 3D-scanned the original propeller to create a digital master, then printed it in SS316L stainless steel on the Vipra AM. Manufacturing was staged: the central hub was machined first, penetrant testing confirmed no cracks or porosity, and three blades were then deposited on it. Machining took about 100 hours, the most demanding step; because the blades are twisted freeform surfaces with very few usable datums, the team rescanned after each stage and compared results with the digital master to confirm allowance and keep a full record. Deposition accounted for only 20 of the project's roughly 120 hours, with the rest going to machining and post-processing—a ratio Caracol says is representative for precision metal parts. The lead-time and cost reductions come from skipping mold making and foundry scheduling queues, getting the vessel back into service sooner; the scanning and comparison workflow also leaves a reusable digital file that offers a manufacturing path for similar spare parts without relying on original drawings. For the metal additive manufacturing supply chain, this means replacement demand for large stainless steel marine parts can bypass traditional casting tooling and rely instead on a short scan–deposit–machine workflow. Value for powder buyers: (1) Marine propeller replacements like this create steady demand for SS316L stainless steel powder, so suppliers should watch their ability to supply coarse particle size grades for WAAM; (2) a 60% cut in lead time means powder suppliers need stocking and delivery rhythms that support fast small-batch response; (3) scan-based reconstruction replacing drawings will bring more spare-parts orders without CAD files, so powder suppliers should partner with additive service providers to capture this fragmented but time-critical purchasing.
