Experimental Determination of the Mechanical Properties of Onyx Material

Abstract

Abstract. The main objective of the study is to determine the mechanical properties of the composite material produced by 3D printing. Experimental verification of the influence of the orientation and thickness of the layers was carried out. The test specimens for the experiment are fabricated by 3D printing from Onyx material using the Fused filament fabrication (FFF) method. The investigation of the mechanical properties is carried out using static tensile testing on the Inova FU-O-160-1260-V1 machine. The shape and dimensions of the test specimens are defined by the ASTM D638-14 standard. The study aims to determine the mechanical properties of Onyx material and specify the influence of the orientation of the layers and the thickness of the specimens on these mechanical properties.
