Abstract

Mechanical properties for material are important in order to produce high quality product. Rapid proto typing is one of the fields that produce product or prototype by using many types of materials. This research was done focusing on studying about the mechanical properties of parts produced using three dimensional printing which is one of the methods of rapid prototyping. The material for this research is zp 130 powder which was machined using ZPrinter 310 Plus. In order to determine the mechanical properties, the study about the theory had been done by reading the journals. Then, the next step was defined the type of material used to produce parts using three dimensional printing. A study about the three dimensional printing and rapid prototyping also had been done in order to enhance knowledge and skills in term of producing parts or prototype. After that, research about the specimen design and standard dimension for testing specimens was done to manage the designing process by using SolidWork software. There were twenty specimens had been machined using ZPrinter 310 plus. Each type of testing needs five specimens which one specimen took five minutes of machining. The final method in order to complete this project was to test the specimens by using four types of testing which were flexural test, charpy impact test, tensile test and compression test. The testing was obtained to get the data of mechanical properties. After completing the test, all data were analyzed in order to get the actual data for mechanical properties which using specific equation for each data. As the final result, the flexural strength for zp 130 powder was 11.9 MPa, impact strength was 40.682 J/m2 , the tensile strength was 2.041 MPa, modulus of elasticity was 8.33 GPa and the compressive strength was 4.28 MPa.
