Abstract
Additive Manufacturing (AM) also known as 3D printing, fabricates an object by addition of material layer by layer and well known for its ability to manufacture the complex objects and reduce material wastage, unlike the conventional manufacturing process. AM comprises a number of technologies, one of them is Digital Light Processing (DLP) which uses liquid photopolymer resin, cured with the help of ultra-violet (UV) light. There are two approaches, top-down and bottom-up. In the latter, the cured layer must stick to the build platform or previously cured layer. Instead, it sticks to the vat bottom, referred as vat sticking and it prevents the further printing process. In this paper, the reasons behind this issue and methods to overcome are reviewed. Anti-stick films have been used as a low-cost optimal solution and number of experiments were conducted.
