Abstract Scope |
The assembly of additively manufactured parts, including both monolithic parts and lattices, has largely been restricted to traditional joining technologies (e.g., welds, adhesives, bolts). In this talk, we present a novel AM-enabled joining technology: interlocking metasurfaces (ILM). ILMs are architected arrays of mating features that create non-permanent joints for additively manufactured parts. We define a design framework and demonstrate how AM enables rapid exploration of the ILM design space. Various designs are fabricated in a broad range of materials from polymers to metals and the performance of selected designs is experimentally evaluated. The selected designs create mechanically robust integral attachment solutions for complex structures such as lattices and vessels.
