Abstract
Reverse Engineering (RE) and Material Extrusion (MEX) based Additive Manufacturing (AM) present a precise and repeatable approach for polymer restoration through repair. A hemispherical additively fabricated dome shaped geometry was damaged via computer numerical control machining and digitized using 3D scanning. A reverse engineered repair patch was modeled based on scanned data and fabricated using MEX process. The patch was adhesively bonded to the parent structure. Metrological deviation analysis confirmed sub - micrometer reconstruction accuracy, with over 94% of the scanned data within ±1?. The adhesively bonded patch showed excellent surface conformance. The findings demonstrate the feasibility of RE based additive repair as an alternative to full part replacement, and contributing to circular economy practices.
