Optimization, Characterization, and Mechanical Properties of Printed Eco UV Resin Using ۳D Printer on Moving Ultraviolet Light Curing

Presently, Three-dimensional printer technology, an exceptionally light curing-based process, has developed intensively. Depending on the light source, many commercial three-dimensional printers are available at low to high prices. Blue light, ultraviolet, and laser are the most common light sources suitable for light projection-based technology. However, improving the interaction between the light source and the material processed is still challenging. The study aimed to find the optimum parameters of distance the moving ultraviolet light to the material and print speed based on curing depth. In this study, a commercial ultraviolet light source was carried out using Cure Beam Ultraviolet Light with a wavelength of ۴۰۵ nm, which was exposed in a dark environment and at room temperature. The material was Eco UV Resin Anycubic, one of the photoliquid types. MiView camera was used to obtain the depth of the curing during the light exposure using a commercial three-dimensional printer. The response surface method optimized the printing parameter with ۱۳ sets of specimens. The specimens were printed in the form of a line shape. Characterization and mechanical properties were investigated using a scanning electron microscope and Shore D Durometer. The results show that the optimum setup printing parameters were ۱۰ mm and ۱ mm/s for distance and print speed, respectively. Furthermore, the optimum parameter setting of curing depth was ۸.۰۲۹ mm. The surface shows the smooth (curing area) and wavy area. The hardness numbers of the optimum parameter were ۶۱.۳ HD  (top) and ۵۸.۵ HD (bottom).
