In this article, details for the increasing properties with the help of 3D printer assisted technique of a material produced by classical sand mould casting method through a technological transformation were presented. At the same time, digital transformation studies were included with the development of online data monitoring systems in mass production. After the design studies were carried out with Solidworks, design verification research with computational fluid dynamics (CFD) and finite element analysis (FEA) have been realized. Solidification, filling-time-temperature analyses, and casting simulation studies of micro and macro shrinkage were carried out using the Anycasting simulation program. Then the intensive use of simulation techniques, the activities that would increase the quality of the product with 3D printers were detailed. The microstructure investigation, chemical analyses, and mechanical tests were performed to prove the positive effect of the 3D printing system. Surface morphology determination results showed that the better outcomes have been obtained from the 3D printing reinforced system. Finally, a unique data monitoring system that could communicate with production equipment for the first time in our country without the need for any external software and license, within the scope of digital industrialization system were explained. With the commissioning of the 3D system, 44.2% increase in efficiency and 33% improvement in quality rates were achieved. The biggest advantage of this system is that the total amount of energy consumed was reduced from 197 mJ to 81 mJ.
