Abstract

Tensile testing is one of the most common mechanical tests performed to understand the properties of materials. Tensile testing is performed to determine elastic and plastic material properties under static load. This method provides helpful information for designers and manufacturers to develop new materials. In tensile tests used for various conditions, there are tensile test specimens of different sizes and shapes. However, in recent years, there has been an increased interest in miniaturized tensile specimens and micro-tensile testing applications instead of standard tensile testing and standard tensile specimens used to determine the mechanical properties of materials. Due to the reduction of test specimen sizes, it is possible to reduce the amount of material and the time taken for specimen preparation. In this study, miniature and standard tensile test specimens were produced using additive manufacturing methods (Fused Deposition Modeling and Stereolithography). A mini tensile mold was designed and fabricated for mini tensile tests. The results showed that mini tensile test specimens can be used instead of standard tensile test specimens.

Keywords
