Ultrasonic imaging is used effectively in medicine, biomedical and industrial fields. Since they can mimic the soft tissues of living things, phantoms are frequently utilized in ultrasonography research in biomedicine. Ultrasonic imaging phantom is used as a tissue-like material to better understand the light propagation in tissue in studies that are difficult to do on human tissue ethically in the development of new technologies.  There are many phantom studies in the literature that mimic human tissue. In these studies, liquid phantoms, which are easy to construct and characterize, have been preferred. Although they are easy to prepare and procure, the most significant disadvantages of liquid phantoms are that they have a short shelf life, deteriorate quickly, and they cannot be designed as layered phantoms with different optical properties. The use of solid phantoms, which are more durable, and long-lasting, optical properties do not change over time, have different optical properties and shapes, and can be designed with multiple layers, becomes more effective and efficient. This study, it is aimed to design, manufacture and validate a long-lasting solid phantom that is durable and optically stable. Ultrasonic imaging phantom was obtained after the prepared solution was poured and frozen on the molds, which were printed using a three-dimensional (3D) printer.  After the design, the optical properties of the solid phantom have been determined. The fabricated tissue-like targeted phantoms were visualized on the ultrasonography device and their optical and acoustic parameters were calculated. As a result of both the images and the data received, it has been revealed that the phantom is successful and problem-free.
