In recent years, Additive Manufacturing has been used in many industrial and domestic application. In this paper, the authors investigate the effects of process parameters on the properties of 3D printing parts using photopolymer material. A DLP 3D printing machine was constructed for experimental research and two control parameters are exposure time T(s) and layer thickness L(mm). The printed specimen will be tested for tensile strength, bending strength and Shore A hardness and will also be measured to investigate the dimension errors. The result can be used to assist machine operators to choose suitable process parameters when printing 3D DLP.
