“…On the other hand, when analysed in terms of internal configurations, it can be deduced that the triangular configuration type shows the highest values of absorption coefficient and sound transmission loss in two of the three configurations. The triangular configuration shows higher absorption due to the cell walls interacting with the ultrasonic wave along the in-plane direction [ 57 ].…”

The 3D printing process allows complex structures to be obtained with low environmental impact using biodegradable materials. This work aims to develop and acoustically characterize 3D-printed panels using three types of materials, each manufactured at five infill densities (20%, 40%, 60%, 80% and 100%) with three internal configurations based on circular, triangular, and corrugated profiles. The highest absorption coefficient values (α = 0.93) were obtained from the acoustic tests for the polylactic acid material with ground birch wood particles in the triangular configuration with an infill density of 40%. The triangular profile showed the best acoustic performance for the three types of materials analysed and, from the point of view of the mechanical tests, it was highlighted that the same triangular configuration presented the highest resistance both to compression (40 MPa) and to three-point bending (50 MPa). The 40% and 60% infill density gave the highest absorption coefficient values regardless of the material analyzed. The mechanical tests for compression and three-point bending showed higher strength values for samples manufactured from simple polylactic acid filament compared to samples manufactured from ground wood particles. The standard defects of 3D printing and the failure modes of the interior configurations of the 3D-printed samples could be observed from the microscopic analysis of the panels. Based on the acoustic results and the determined mechanical properties, one application area for these types of 3D-printed panels could be the automotive and aerospace industries.

This study investigates the effect of printing parameters on the acoustic performance of specimens produced using 3D printing technology. The specimens were fabricated with square and hexagonal cell shapes with 10, 20, 30, and 50 % infill ratios from acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) materials. The sound absorption coefficient and sound transmission loss results of the samples were measured with an impedance tube at 1/3 octave band values in the range of 500–6400 Hz. The highest sound absorption coefficient results were determined for cylindrical samples with a square internal structure made of ABS material with a 50 % infill ratio in the frequency range of 2500–3500 Hz. The sound transmission loss values of the samples vary between approximately 13 and 58 dB at 1/3 octave band values in the range of 500 and 6300 Hz. The highest sound transmission loss values were determined in the sample produced of PLA with a square cell shape at a 30 % infill ratio. It was concluded that different geometric shapes, materials, and infill ratios affect the acoustic performance of parts produced by 3D printing technology.
