Abstract

3D Print Process is a printing process that is included in additive manufacturing, a 3D object creation process by adding material that is heated gradually to form the desired object. The purpose of this study is to determine the mechanical characteristics of the 3D process using PLA material to the tensile and bending strength of the 3D Print process with a variation of the nozzle angle 0o, 30o, 45o, 60o, and 90o. The type of 3D Print used the Hypercube 3D Print machine. The results of the tensile test at each angle have different tensile strengths, the maximum tensile strength that occurs at an angle of 0o with a tensile strength value of 923.33389 N and the minimum tensile strength value occurs at an angle of 90o with a tensile strength value of 393,746 N. On the test results bending based on the variation of the nozzle angle 0o, 30o, 45o, 60o, 90o, the bending test results at each angle have different bending strengths, the maximum bending strength results occur at an angle of 30o with a value of 3409,1153 N and the value of the minimum bending strength occurs at angle of 45o with a value of 137.03456 N.
