Direct Light Processing (DLP) is a 3D printer that uses resin in the product manufacturing process. The resin is formed through a curing process using UV light. The cast pattern is a replica of the object that will be made in the metal casting process. Cast patterns are usually made using wood or resin. In this paper, discussed the optimization of DLP 3D printing parameters for the cast pattern manufacturing process. The parameters discussed are thickness and exposure time. The data analyzed is the time of production and the accuracy of the dimensions of the resulting product. This method can be used to determine the optimum parameters that can be used to produce products with accurate dimensions and short production times. The results obtained are the thickness and exposure time parameters affect the production time significantly. Meanwhile, the accuracy of product dimensions does not have a significant effect. © 2023 Author(s).
