Acoustic characterization of additive manufactured layered porous materials
Acoustic characterization of additive manufactured layered porous materials
In the present study, acoustic properties of layered porous materials produced by Fused Filament Fabrication (FFF) technique of Additive Manufacturing (AM) have been investigated. The porous materials are fabricated by using different infill percentage of materials in the direction of fabrication, which leads to layered porous material of various pore sizes along the direction of fabrication. Samples with different combinations of infill percentages are fabricated, and their sound absorption coefficient is measured by using two microphone impedance tube technique. Measured results indicate that the sound absorption coefficient of additive manufactured porous materials can be tuned to the required frequency range by changing the combination of infill percentages. The results and fabrication technique presented here gives an alternative method to fabricate layered porous materials.

Abstract
In the present study, acoustic properties of layered porous materials produced by Fused Filament Fabrication (FFF) technique of Additive Manufacturing (AM) have been investigated. The porous materials are fabricated by using different infill percentage of materials in the direction of fabrication, which leads to layered porous material of various pore sizes along the direction of fabrication. Samples with different combinations of infill percentages are fabricated, and their sound absorption coefficient is measured by using two microphone impedance tube technique. Measured results indicate that the sound absorption coefficient of additive manufactured porous materials can be tuned to the required frequency range by changing the combination of infill percentages. The results and fabrication technique presented here gives an alternative method to fabricate layered porous materials.
