Investment Casting process is the promising method for manufacturing of complex component with better surface finish and dimensional accuracy. Development of 3D printing or rapid prototyping has given opportunities for the mass customization and production of complex designs having CAD model. In past few years, rapid prototyping has been integrated to enhance efficacy of investment casting process called as rapid investment casting process or hybrid investment casting process. This present paper is focused on review of effect of fused deposition modeling (FDM) printing parameters on quality of printed pattern and use of 3D printable materials in different steps of investment casting process with their benefits and limitations to improve productivity, accuracy, mechanical properties, and surface finish of the final component. Applications and benefits of hybrid investment casting process to manufacture different industrial product are also considered. There are certain challenges in implementation of this process such as ceramic shell cracking, pattern burning temperature, and pattern quality. These are also discussed in detail. These challenges will become separate topic of research for further advancement in hybrid investment casting process.
