Sound‐Insulation Performance of Polylactic Acid Parts 3D Printed by Fused Filament Fabrication with Functionally Graded Porous Structure for Effective Noise Reduction

Sound‐Insulation Performance of Polylactic Acid Parts 3D Printed by Fused Filament Fabrication with Functionally Graded Porous Structure for Effective Noise Reduction

Abstract The emergence of 3D printing technology has enabled the fabrication of absorbers with functionally graded (FG) porous structure and controlled porosity that can absorb sound waves across a broader frequency range. In this study, sound absorption properties of fused filament fabrication (FFF...
