Digital light processing (DLP) 3D printing is an additive manufacturing (AM) process that is utilized to produce parts by means of the photopolymerization process in which resin is cured by UV light. Vat photo-polymerization is a type of AM. it's a liquid bath of a polymeric resin which is cured layer by layer through precise control with the assistance of stepper motor UV light. Printing time, layer thickness, and lumens of the light play a crucial role within the printing. A series of specimens was designed, printed, and tested. Total printing time, layer thickness, and layer exposure time were examined. We utilized a 365 nm frequency of photopolymer vat. This paper studied printing parameters like surface roughness, printing speed and role of layer size, etc. It has found that if the printing speed 250 mm/min then the surface quality will be better otherwise surface roughness will increase if it will be greater than 250 mm/min.
