Influence of Structure on Mechanical Properties of 3D Printed Objects

Additive Manufacturing (AM), the relatively young manufacturing technology of layer-based automated fabrication process for making three-dimensional physical objects directly from 3D CAD data set was originally called Rapid Prototyping (RP) when the first commercial process – Stereolitography was entered the market in 1987. This technology is still frequently called Rapid Prototyping. The main objective of research was to determine the impact of sample's structure on the tensile strength of 3D printed samples. Test samples were prepared on a Z Corporation's 3D printer model Z310, with variations of internal geometrical structure. Results of tensile test revealed that the honeycomb structured samples exhibit the highest strength.
