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.
