Noise and lighting are significant factors that have an impact on our health, environment, production quality, etc. The purpose of this paper is to investigate sound and light absorption properties of 3D-printed polyethylene terephthalate glycol (PETG) material specimens that were manufactured with two types of holes, namely with circular and square-shaped holes. In addition, the holes were printed with different dimensions, depths, shapes, and surface spacings. Different factors influencing the material´s ability to absorb sound and light were evaluated in this paper. It was found in this study that the type of holes, their spacing and depth have a big influence on sound and light absorption properties of the investigated samples compared to the smooth PETG material.
