| Abstract Scope |
We report on the development of a new polymer-metal composite structure that combines additive manufacturing and electroplating. The process starts with Digital Light Synthesis, a rapid vat photopolymerization process, that provided rigid polyurethane honeycomb structures. The honeycomb parts had a 9 × 8 cell arrangement with overall dimensions of 48.5 mm × 48 mm × 30 mm. 100 µm-thick NiCo electroplating on these structures provided a 6-fold improvement in elastic modulus and a 3-fold rise in strength, compared to the uncoated parts. The developed polymer-metal honeycomb composite architecture provides a new approach to the design and implementation of lightweight structural materials and impact-absorbing parts. The highly scalable polymer AM and well-established electroplating techniques offer a fast and cost-effective alternative to the direct metal printing of cellular structures and lattice parts. |
