There is a discussion of the relevant 3D printing processes and their applications. 3D printing technology is transforming the practice of medicine and making work easier for architects. The aerospace industry employs them because of the possibility of manufacturing lighter structures to reduce weight. 3D printing technology is transforming the practice of medicine and making work easier for architects. Studies are reviewed which were about the products made in additive manufacturing processes. However, there is still a lot of work and research to be accomplished before 3D printing technologies become standard in the manufacturing industry because not every commonly used manufacturing material can be handled. The accuracy needs improvement to eliminate the necessity of a finishing process. The continuous and increasing growth experienced since the early days and the successful results up to the present time allow for optimism that additive manufacturing has a significant place in the future of manufacturing.
