Abstrakt: A novel design for a specimen and a grip for tensile testing of 3D printed materials is proposed and investigated in the paper. The specimen design is based on ISO 527-2 standard and it is intended for the upright 3D printing and investigation of influence of the 3D printing orientation on the mechanical properties of the 3D printed material. Two specimens were 3D printed from PLA material and successfully tested in a tensile testing machine. Grips, made from 3D printed composite materials (onyx reinforced with graphite fibers), were designed and used for fixation of the specimen in the machine jaws. Obtained results for ultimate tensile strength were in the expected range for PLA material. [ABSTRACT FROM AUTHOR]
