Abstract
This paper describes the development of the additive PolyJet technology aimed at designing and fabricating the samples of acoustic metamaterials with high sound absorption. The samples in the form of cellular thin-walled periodic structures with links between the cells are synthesized by photopolymer material using the additive technology. The peculiarities of the synthesized process are studied and optimal parameters are found to provide the required shape of the samples. The results of experimental study of sound absorption efficiency of the synthesized samples are also presented that demonstrate rather high sound absorption efficiency.
