Influence of Printing Orientation on the Elastic Modulus of PA12 Specimens Obtained by SLS Technology

This paper describes a study that examined the effect of printing orientation on the mechanical characteristics, especially the modulus elasticity, of additive manufacturing (AM)—grade polyamide material. Selective laser sintering (SLS) technology was used to create tensile specimens composed of polyamide 12 (PA12). A specific type of specimen according to the ISO 527-2 standard for tensile specimens was studied to examine mechanical properties. The study looks at two batches of specimens exposed to tensile stress in various orientations inside the powder bed. Mechanical property evaluation utilizes a universal testing equipment, the Simadzu AGS-X. The comparison of horizontally and vertically printed samples attempts to determine if print orientation has a substantial impact on the mechanical qualities of the components.
