Effects of Printing Angle on Mechanical Characteristics of Resin Castable Wax V1

Abstract

Material additive or 3D printing technology has been recognized as a future manufacturing technique. The mechanical properties of products manufactured using 3D printing technology depend on many factors, especially the printing angle. Resin Castable Wax can be used as a matrix or scaffold for sensor devices in 3D printing. In this study, we explore the effects of printing angle on the mechanical properties of Resin Castable Wax V1 using the 3D stereolithography printing method. The samples are printed at three different printing angles of 0, 45, and 90°. Increasing the printing angle from 0 to 90° improves the tensile and compressive strengths. The sample printed at the angle of 90° shows the highest ultimate tensile and compressive strengths of 23.13 and 124.97 MPa, respectively, and vice versa for the sample printed at 0º. Because of the gradual inclination of the material toward the direction of load force and the larger printing boundary at a higher printing angle, the mechanical properties are improved when the printing angle is increased. These findings can be used to choose an appropriate printing angle for Resin Castable Wax V1.
