Hexagon Unveils Rapid Reverse-Engineering System for Aircraft Cabin Maintenance

Hexagon Unveils Rapid Reverse-Engineering System for Aircraft Cabin Maintenance
Hexagon, a prominent provider of measurement technologies, has launched an innovative rapid reverse-engineering workflow designed to enhance aircraft cabin maintenance, repair, and overhaul (MRO) operations. This new system addresses a persistent challenge in refurbishing aging aircraft interiors: the replacement of parts that lack existing CAD data. Components such as seat shrouds, armrests, tray tables, and galley hardware often suffer from cracking, delamination, or obsolescence, complicating their reproduction and replacement.
Advancing On-Demand Manufacturing for Aircraft Interiors
On-demand manufacturing has become increasingly popular for reproducing hard-to-source aircraft parts. However, the absence of accurate CAD data has traditionally impeded this process, as reliance on manual measurements or outdated drawings frequently results in errors and costly rework. While scan-based reverse engineering offers a potential solution, it typically demands specialist expertise and involves time-consuming manual redrawing of 3D models from incomplete scan data. The use of non-specialist CAD software can further exacerbate delays.
Hexagon’s new system, developed by its Portable Metrology Division, centers on the Geomagic Design X software platform. This solution integrates direct control of handheld 3D scanners with automated features such as Region Segmentation, Modelling Wizards, Auto Sketch, and NURBS surfacing. According to Hexagon, the system can transform even complex, freeform shapes into fully editable, parametric CAD models with complete design history, achieving reconstruction speeds three to eight times faster than traditional scan-based methods.
Aziz Tahiri, Hexagon’s global director for aerospace and defense, highlighted the growing importance of reverse engineering in interior refurbishment. He noted increasing interest from defense customers in mobile units that combine scanning arms, reverse engineering software, and 3D printers within a single container, enabling damaged parts to be scanned, rebuilt, and repaired on site. Tahiri emphasized that with Geomagic Design X and accessible handheld 3D scanning equipment, reverse engineering directly into CAD can be accomplished within hours, offering a highly productive workflow readily adoptable by engineers and manufacturing teams.
User-Friendly Technology Designed for Field Conditions
Hexagon stresses that the system requires no specialist training for MRO technicians or manufacturing engineers. The rugged and portable Atlascan Pro scanner allows users to capture small parts from any angle, even under unstable hangar or field conditions. The software’s integrated Accuracy Analyzer continuously verifies constructed surfaces against scan data throughout the process, minimizing the risk of rework and fit issues. Completed models can be seamlessly exported to major CAD platforms such as Solidworks, Siemens NX, Autodesk Inventor, or PTC Creo, facilitating the production of replacement parts through machining or 3D printing with minimal trial and error.
Despite its potential, Hexagon’s rapid reverse-engineering system faces several challenges. Integrating the new workflow into established aircraft maintenance procedures may require operational adjustments, and maintaining consistent accuracy and reliability will be essential for broad industry adoption. Some traditional maintenance providers may exhibit reluctance toward adopting new technologies, and market responses could include skepticism regarding the system’s effectiveness and cost-efficiency. Furthermore, competitors are expected to respond by developing or enhancing their own reverse-engineering solutions to preserve market share.
As the aviation sector continues to pursue faster and more reliable maintenance methodologies, Hexagon’s system represents a notable advancement. Its ultimate impact will depend on how successfully it navigates integration challenges, ensures dependable performance, and gains acceptance within the industry.
