Abstract

In this research we developed the methods and technologies for manufacturing sound-Absorbing structures (SAS) samples using Dimension SST 1200 and Envisiontec Perfactory XEDE units. While testing the technique, the shortcomings of both units were identified. To eliminate the identified shortcomings, we formulated some recommendations and adjusted the main stages of manufacturing SAS with the application of these methods. Experimental acoustic studies of the produced reference samples of the SAS on an interferometer with normal incidence of waves were carried out. Acoustic tests of samples of SAS manufactured with consideration of the developed technological solutions showed good sustainability of the obtained results, we revealed strong correlation with the samples from polymer composite materials manufactured using standard plant technologies.
