The rolling process is one of the common and widely used methods in manufacturing and forming various parts. The rolling process has a significant effect on the mechanical properties and microstructure of materials, which making it important in the manufacturing of products. 3D printing or additive manufacturing is a of the new method in producing parts that allows for the direct creation of parts from digital models. This process is based on creation parts layer by layer and can produce various parts quickly and with high precision. The unique features of additive manufacturing, such as design freedom, no need to dies and auxiliary equipment, and the ability to produce complex and integrated parts, have caught the attention of many industries such as aerospace, oil and gas, marine and automotive industries to use this method. In the other hand, problems such as microstructure defects, distortion, residual stress and anisotropy of mechanical properties are among the challenges in additive manufactured or 3D printed parts. Using the rolling process to modify 3D printed parts is one way to improve the microstructure and mechanical properties of materials. By combining the rolling process with additive manufacturing, hardness, strength, and elongation can be increased by homogenizing and refining grains of the structure. Also, this process can reduce distortion and residual stress in the additive manufactured parts.
