Shining 3D's FreeScan Trak quantifies hull geometry for aluminum electric catamaran

Shining 3D's FreeScan Trak wireless large-area tracking scanner was used by Chinese engineer and sailor Hu Wei to capture full hull geometry of the HighWei 66, an aluminum-alloy electric catamaran designed for long-range ocean travel. The vessel, which carries no diesel engine and no traditional rudder, relies on variable-pitch electric propulsion and control algorithms. The FreeScan Trak system measured critical waterline cross-section dimensions without physical markers, generating color deviation maps that compared the as-built hull against the original CAD model. Engineers used the scan data to refine structural designs and run CFD simulations to assess how welding-induced thermal deformation affected hydrodynamic resistance, significantly shortening the development cycle from prototype to production-ready vessel.

This application sits at the intersection of two underappreciated AM value-chain realities: the critical role of metrology in production workflows, and the growing use of AM-adjacent digital tools in marine and energy verticals. While the HighWei 66 is not an additively manufactured vessel, the case demonstrates how 3D scanning-a technology that shares metrology infrastructure with AM-enables the kind of dimensional governance that makes AM adoption viable in adjacent fabrication processes. The marine segment remains fragmented and early for AM, but the use of large-area tracking scanners to validate aluminum hull geometry points to a broader pattern: as production scales in metal-intensive verticals, the inspection and feedback loop becomes as important as the printing itself. Shining 3D, headquartered in Hangzhou, is leveraging its domestic industrial base to serve a niche that combines shipbuilding, electric propulsion, and digital workflow integration.

For Shining 3D, the practical takeaway is that its FreeScan Trak series has found a credible reference in a demanding structural application-aluminum welding at marine scale-where conventional tape measures and calipers fail. The company's next step is to convert this single-vessel success into repeatable workflow references for other shipbuilders or metal fabricators. For buyers evaluating large-area metrology, the key question is whether the system's markerless tracking and deviation-mapping software can integrate with existing CAD and CFD pipelines without custom engineering. This is a solid case study, not a market-moving event, but it reinforces that metrology is becoming a necessary complement to production-scale metal AM and advanced fabrication.
