标题: UAE Delivers Its First 3D-Printed Marine Propeller; WAAM Cuts Lead Time by 60% [打印本页] 作者: admin 时间: 2026-10-20 20:06 标题: UAE Delivers Its First 3D-Printed Marine Propeller; WAAM Cuts Lead Time by 60% Nanjixiong learned that Dubai engineering company JOME Engineering has successfully 3D printed a 26 kg stainless-steel marine propeller using wire arc additive manufacturing (WAAM). The part was reconstructed from a 3D scan of the original because the original equipment had no remaining CAD drawings or tooling.

The project was completed at JOME's Dubai factory using the Vipra AM robotic WAAM platform from Italian large-format additive manufacturing company Caracol. The material was SS316L stainless steel. Caracol calls it the UAE's first 3D-printed marine propeller. Compared with conventional casting, lead time was reduced by about 60% and cost by about 40%.
Manufacturing was carried out in stages: the central hub was first machined and confirmed free of cracks and porosity by penetrant testing; three blades were then deposited onto it. The project took about 120 hours in total, of which deposition accounted for only 20 hours, while machining and post-processing took about 100 hours. After each stage, the team rescanned the part and compared it with the digital model to control alignment error.
Nanjixiong's observations
Marine spare parts often face the challenges of “no drawings, low volumes, and urgent delivery.” WAAM combined with scanning and reverse engineering offers a practical route. However, machining still accounts for most of the lead time, and the post-processing bottleneck for precision freeform metal AM parts remains unresolved.
