The use of the additive manufacturing method in the casting industry is increasing day by day. The production of reverse angled and complex shaped casting parts, which cannot be produced with the classical modeling technique, can also be produced very easily with this method. On the other hand, it is very fast, especially in terms of rapid production of prototype castings, which can be directly molded without the need for model production. In this study, a 3D Printer with binder jet was designed and produced firstly. 3D Printer; It consists of 3 parts, the main chassis, the sand spreader and the spraying part. In this printer, which was produced afterwards, sand molds were produced with different nozzle advance speeds, different catalyst ratios and sand grain sizes. The consumables used in the production of sand molds are silica sand, furan resin and catalyst. The mechanical properties of the produced samples were determined by performing compression and gas permeability tests. Afterwards, it was determined which of the produced samples were more suitable for a sand casting mold by comparing the results obtained from similar studies in the literature. In this study, a new printer was designed with direct spray technique without using cartridges and preliminary studies were carried out successfully.
