Abstract

Faizal Fahmi, 2023 "ANALYSIS OF THE STRUCTURE OF 3D PRINTING RESULTS WITH LCD RESIN TYPES ON MECHANICAL PROPERTIES" Thesis Report of Mechanical Engineering, Faculty of Engineering and Computer Science, Pancasakti University, Tegal. 3D printing is the process of creating three-dimensional objects from a CAD (computer-aided design) model. Usually by adding layer by layer printing material. In this study, a quantitative method was used with a 3D printer to print 3D printer results made from resin type LCD on mechanical properties. After conducting the research, it was found that the specimens in the horizontal print position were able to accept the greatest load in the second test, namely in the tensile test of 4.19KN while in the bending test it was 3.75KN. The maximum tensile stress received by the horizontal print position specimen is 39.89MPa compared to the vertical print position test specimen, which is 31.38MPa. The maximum bending stress received by the specimen in the horizontal print position is greater, namely 127.30MPa and for the specimen in the vertical print position, it is 118.60MPa. From the test results it can be concluded that specimens in a horizontal printing position with a fast printing time compared to specimens in a vertical printing position will have an additional effect of strength and more comfort on the specimen.
