A review published in Virtual and Physical Prototyping explores the growing field of additively manufactured acoustic metamaterials (ACA-Meta), highlighting how 3D printing technologies enable novel designs for effective sound absorption across diverse applications. Authored by researchers from Khalifa University and Dassault Aviation, the paper classifies acoustic metamaterials into perforated, slotted, cellular, and hybrid types and investigates how additive manufacturing enhances their performance.
Expanding acoustic control with 3D printing
Additive manufacturing offers unique benefits for acoustic metamaterials, enabling precise control over geometry, material distribution, and internal architecture. This level of control allows researchers and engineers to tailor acoustic behavior at specific frequency ranges, while simultaneously optimizing for weight, mechanical strength, and structural complexity.
