This study was conducted to contribute to the vitalization of the food industry through future food tech analysis of 3D printing technology. Interest in the future food industry of sustainability is increasing in the 4th industrial revolution, and the global food market trend is developing food tech that combines innovative technologies. Research to converge with the 3D printing field and converge to various food tech fields is in progress, and it is intended to be used as a growth engine to seek the development of the food industry. Materials applicable to 3D printing were investigated. Among them, 3D printing technology applicable to grains, proteins and starches, dairy products and sugar materials was investigated. 3D printing technology that can be applied to food can be classified into fused deposition modeling (FDM), color jet printing (CJP), selective laser sintering (SLS) & hot air sintering, and binder jetting. Also, the type of food material and nozzle used is different depending on the 3D printing technology. The results of this study provided information on the development of 3D printing technology and materials, and research trends are examined from the food tech perspective for the application of 3D printing technology as a future food industry. Thus, innovative development for the sustainable future food industry will proceed with food tech fused with 3D printing technology in the era of the 4th industrial revolution.
