Recent Developments in 3D Printing Technologies: Review

3D Printing is a technology which is based on additive manufacturing. This technology has a potential to change the manufacturing industry by manufacturing product in the shortest time period where at first the same product required days, months or years. The study on these printers and their software is to reduce the cost of printers as compared to one already present in the market. This paper is based on the types of 3D printing methods used from the early 1980s till today and their hardware and software used.
