Although essential, cultivating a deep understanding of the fundamental theory and design principles is insufficient alone, in the practical advancement of AMMs and PCs. Equally important is the physical realization of these artificial structures for tangible prototyping and experimental investigation; however, such aspects are seldom discussed in literature. Herein, the fabrication and assembly approaches for AMMs and PCs are critically examined, with a tight coupling of theoretical and experimental considerations. Crucial parameters like operating frequency, materials, and geometry for efficient structural implementation are addressed. Herein, fabrication methods for specific structure types are categorized under “single-step fabrication” including printing and machining and “multi-step fabrication” like microfabrication and molding. Various “assembly” techniques are proposed, such as for ordering colloidal assemblies or fastening components without adhesives. This framework uncovers innovative designs, e.g., origami-based structures with conductive coating, only accessible if fabrication and assembly aspects form an integral part of the initial design phase. By establishing a greater understanding and awareness of these methods, a host of undiscovered pathways, opportunities, and research gaps is revealed, supporting a fresh paradigm for innovation. date: 2021-02 publisher: Wiley official_url: https://doi.org/10.1002/adem.202000988 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1823977 doi: 10.1002/adem.202000988 lyricists_name: Bansal, Shubhi lyricists_name: Choi, Christabel lyricists_name: Subramanian, Sriram lyricists_id: SBANS80 lyricists_id: CMKCH13 lyricists_id: SSUBR74 actors_name: Choi, Christabel actors_id: CMKCH13 actors_role: owner full_text_status: public publication: Advanced Engineering Materials volume: 23 number: 2 article_number: 2000988 citation: Choi, C; Bansal, S; Münzenrieder, N; Subramanian, S; (2021) Fabricating and Assembling Acoustic Metamaterials and Phononic Crystals.
